Let's divide 91690265 by 87
Our goal is to divide 91690265 by 87.

Going ahead to step 1:
When dividing 9 by 87, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 87

Going ahead to step 2:
87 can be fit into 91 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 87 from 91 leaves us with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 87

Going ahead to step 3:
87 goes into 46 0 times with a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 46 to get 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 87

Moving on to step 4:
The number 87 fits into 469 5 times, leaving a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 105.0
Subtracting 435 from 469 leaves us with 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 87

Going ahead to step 5:
340 divided by 87 is 3 with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 1053.0
If we subtract 261 from 340, we get 79.
Append the next digit (2) from the dividend to 79 and continue with: 792 / 87

On to step 6:
87 goes into 792 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 10539.0
If we subtract 783 from 792, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 87

Step 7:
87 can be fit into 96 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 105391.0
The remainder is 9 after subtracting 87 from 96.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 87

Going ahead to step 8:
95 divided by 87 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1053911.0
Deduct 87 from 95 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
The number 87 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 1053911.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
When dividing 800 by 87, we get 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 1053911.09
The remainder is 17 after subtracting 783 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 11:
If we divide 170 by 87, we get 1 and a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 1053911.091
Subtracting 87 from 170 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 12:
The number 87 fits into 830 9 times, leaving a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 1053911.0919
Subtract 783 from 830 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
87 can be fit into 470 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1053911.09195
Subtract 435 from 470 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
If we divide 350 by 87, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1053911.091954
If we subtract 348 from 350, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 15:
87 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 1053911.091954
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 16:
87 goes into 200 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 1053911.09195402
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 1053911.09195402 with a remainder of 2.6e-08.
