### 2.6.10 The integer Euclidean quotient : `iquo intDiv`

`iquo` (or `intDiv`) returns the integer quotient q of the Euclidean division of two integers a and b given as arguments. (a=b*q+r with 0≤ r< b).
For Gaussian integers, we choose q so that b*q is as near by a as possible and it can be proved that r may be choosen so that |r|2 ≤ |b|2/2.
Input :

`iquo(148,5)`

Output :

`29`

`iquo` works with integers or with Gaussian integers.
Input :

`iquo(factorial(148),factorial(145)+2 )`

Output :

`3176375`

Input :

`iquo(25+12*i,5+7*i)`

Output :

`3-2*i`

Here a−b*q=−4+i and |−4+i|2=17<|5+7*i|2/2=74/2=37
