Let's divide 87131965 by 963
Our goal is to divide 87131965 by 963.

Moving on to step 1:
If we divide 8 by 963, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 963

Step 2:
87 divided by 963 is 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Fetch the next digit (1) from the dividend, attach it to 87 and continue: 871 / 963

Step 3:
If we divide 871 by 963, we get 0 and a remainder of 871.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 871, we end up with 871.
Bring next digit (3) of the dividend behind the 871 and repeat the process: 8713 / 963

Let's proceed to step 4:
8713 divided by 963 is 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 8667 from 8713 leaves us with 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 963

On to step 5:
963 goes into 461 0 times with a remainder of 461.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we subtract 0 from 461, we get 461.
Include the next digit (9) from the dividend after 461, then repeat: 4619 / 963

Step 6:
963 can be fit into 4619 4 times, resulting in a remainder of 767.
The next digit of our result is 4. 
Result so far: 904.0
Subtract 3852 from 4619 to get 767.
Fetch the next digit (6) from the dividend, attach it to 767 and continue: 7676 / 963

Going ahead to step 7:
963 can be fit into 7676 7 times, resulting in a remainder of 935.
Write down 7 as next digit of the result. 
Result so far: 9047.0
Deduct 6741 from 7676 and we're left with 935.
Include the next digit (5) from the dividend after 935, then repeat: 9355 / 963

Advancing to step 8:
9355 divided by 963 is 9 with a remainder of 688.
Put 9 as the next digit of the answer. 
Result so far: 90479.0
If we take 8667 away from 9355, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Moving on to step 9:
963 goes into 6880 7 times with a remainder of 139.
Record the quotient 7 as the next digit in the result. 
Result so far: 90479.7
Subtract 6741 from 6880 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 10:
963 can be fit into 1390 1 times, resulting in a remainder of 427.
Use 1 as the next digit of our solution. 
Result so far: 90479.71
Subtract 963 from 1390 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Advancing to step 11:
4270 divided by 963 is 4 with a remainder of 418.
Record the quotient 4 as the next digit in the result. 
Result so far: 90479.714
Subtracting 3852 from 4270 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 12:
If we divide 4180 by 963, we get 4 and a remainder of 328.
Record the quotient 4 as the next digit in the result. 
Result so far: 90479.7144
If we take 3852 away from 4180, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final outcome is 90479.7144, with a leftover of 0.00328.
