Let's divide 87786144 by 91
We want to divide 87786144 by 91.

Moving on to step 1:
If we divide 8 by 91, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 91

Step 2:
When dividing 87 by 91, we get 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 91

Step 3:
91 goes into 877 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 819 from 877 and we're left with 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 91

Going ahead to step 4:
The number 91 fits into 588 6 times, leaving a remainder of 42.
The next digit of our result is 6. 
Result so far: 96.0
If we take 546 away from 588, we end up with 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 91

Moving on to step 5:
When dividing 426 by 91, we get 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 964.0
Deduct 364 from 426 and we're left with 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 91

Let's proceed to step 6:
The number 91 fits into 621 6 times, leaving a remainder of 75.
Use 6 as the next digit of our solution. 
Result so far: 9646.0
The remainder is 75 after subtracting 546 from 621.
Grab the next digit (4) from the dividend, add it to 75, then carry on: 754 / 91

On to step 7:
754 divided by 91 is 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 96468.0
If we take 728 away from 754, we end up with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 91

On to step 8:
91 can be fit into 264 2 times, resulting in a remainder of 82.
The next digit of our result is 2. 
Result so far: 964682.0
Subtracting 182 from 264 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
820 divided by 91 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 964682.9
Deduct 819 from 820 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
91 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 964682.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
If we divide 100 by 91, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 964682.901
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
The number 91 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 964682.901
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
91 goes into 900 9 times with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 964682.90109
The remainder is 81 after subtracting 819 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 14:
The number 91 fits into 810 8 times, leaving a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 964682.901098
The remainder is 82 after subtracting 728 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 15:
The number 91 fits into 820 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 964682.9010989
If we subtract 819 from 820, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 16:
91 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 964682.9010989
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 964682.9010989 with a remainder of 1e-08.
