Let's divide 91660 by 4
We want to divide 91660 by 4.

Step 1:
If we divide 9 by 4, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 8 away from 9, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

Going ahead to step 2:
When dividing 11 by 4, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 8 from 11, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 4

Going ahead to step 3:
If we divide 36 by 4, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
The remainder is 0 after subtracting 36 from 36.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 4

Moving on to step 4:
6 divided by 4 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 2291.0
If we subtract 4 from 6, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 4

Step 5:
20 divided by 4 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 22915.0
Deduct 20 from 20 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 6:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22915.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22915.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 22915.0, with a leftover of 0.0.
