86857090 divided by 963 
We're looking to find how many times 963 goes into 86857090.

Going ahead to step 1:
When dividing 8 by 963, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 963

Going ahead to step 2:
963 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (8) from the dividend and append it to 86, then repeat: 868 / 963

Let's proceed to step 3:
If we divide 868 by 963, we get 0 and a remainder of 868.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 868, we get 868.
Take the next digit (5) from the dividend and append it to 868, then repeat: 8685 / 963

On to step 4:
The number 963 fits into 8685 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 8667 from 8685 to get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 963

Step 5:
963 goes into 187 0 times with a remainder of 187.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we subtract 0 from 187, we get 187.
Append the next digit (0) from the dividend to 187 and continue with: 1870 / 963

Going ahead to step 6:
The number 963 fits into 1870 1 times, leaving a remainder of 907.
Write down 1 as next digit of the result. 
Result so far: 901.0
If we subtract 963 from 1870, we get 907.
Grab the next digit (9) from the dividend, add it to 907, then carry on: 9079 / 963

Step 7:
963 can be fit into 9079 9 times, resulting in a remainder of 412.
Use 9 as the next digit of our solution. 
Result so far: 9019.0
Subtract 8667 from 9079 to get 412.
Append the next digit (0) from the dividend to 412 and continue with: 4120 / 963

Step 8:
If we divide 4120 by 963, we get 4 and a remainder of 268.
Use 4 as the next digit of our solution. 
Result so far: 90194.0
Deduct 3852 from 4120 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 9:
The number 963 fits into 2680 2 times, leaving a remainder of 754.
Use 2 as the next digit of our solution. 
Result so far: 90194.2
If we take 1926 away from 2680, we end up with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Moving on to step 10:
963 can be fit into 7540 7 times, resulting in a remainder of 799.
Put 7 as the next digit of the answer. 
Result so far: 90194.27
The remainder is 799 after subtracting 6741 from 7540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

Advancing to step 11:
When dividing 7990 by 963, we get 8 with a remainder of 286.
The next digit of our result is 8. 
Result so far: 90194.278
If we subtract 7704 from 7990, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 12:
963 goes into 2860 2 times with a remainder of 934.
The number 2 becomes the next digit in our result. 
Result so far: 90194.2782
The remainder is 934 after subtracting 1926 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

Step 13:
963 goes into 9340 9 times with a remainder of 673.
Use 9 as the next digit of our solution. 
Result so far: 90194.27829
Subtract 8667 from 9340 to get 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Advancing to step 14:
6730 divided by 963 is 6 with a remainder of 952.
The number 6 becomes the next digit in our result. 
Result so far: 90194.278296
Subtract 5778 from 6730 to get 952.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9520, and continue the process.

Step 15:
9520 divided by 963 is 9 with a remainder of 853.
The next digit of our result is 9. 
Result so far: 90194.2782969
Subtract 8667 from 9520 to get 853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8530, and continue the process.

Advancing to step 16:
963 goes into 8530 8 times with a remainder of 826.
Use 8 as the next digit of our solution. 
Result so far: 90194.27829698
If we take 7704 away from 8530, we end up with 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

The final outcome is 90194.27829698, with a leftover of 8.26e-07.
