Let's divide 12091 by 88
Let's see how many times 88 fits into 12091.

Let's proceed to step 1:
If we divide 1 by 88, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 88

Moving on to step 2:
88 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 88

Moving on to step 3:
The number 88 fits into 120 1 times, leaving a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 88 from 120 and we're left with 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 88

Moving on to step 4:
When dividing 329 by 88, we get 3 with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 264 from 329, we get 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 88

Let's proceed to step 5:
88 goes into 651 7 times with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtracting 616 from 651 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 6:
350 divided by 88 is 3 with a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 137.3
Subtracting 264 from 350 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 7:
88 goes into 860 9 times with a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 137.39
If we take 792 away from 860, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
When dividing 680 by 88, we get 7 with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 137.397
Deduct 616 from 680 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
If we divide 640 by 88, we get 7 and a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 137.3977
Subtract 616 from 640 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 137.3977, and the remainder is 0.00024.
