81569021 ÷ 963 
Our goal is to divide 81569021 by 963.

Advancing to step 1:
963 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 963

Let's proceed to step 2:
81 divided by 963 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 963

Step 3:
963 goes into 815 0 times with a remainder of 815.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 815 to get 815.
Append the next digit (6) from the dividend to 815 and continue with: 8156 / 963

Moving on to step 4:
963 goes into 8156 8 times with a remainder of 452.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 7704 from 8156, we get 452.
Append the next digit (9) from the dividend to 452 and continue with: 4529 / 963

Step 5:
963 can be fit into 4529 4 times, resulting in a remainder of 677.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Deduct 3852 from 4529 and we're left with 677.
Bring next digit (0) of the dividend behind the 677 and repeat the process: 6770 / 963

Advancing to step 6:
When dividing 6770 by 963, we get 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 847.0
If we take 6741 away from 6770, we end up with 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 963

Advancing to step 7:
963 goes into 292 0 times with a remainder of 292.
Put 0 as the next digit of the answer. 
Result so far: 8470.0
Deduct 0 from 292 and we're left with 292.
Append the next digit (1) from the dividend to 292 and continue with: 2921 / 963

Going ahead to step 8:
When dividing 2921 by 963, we get 3 with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 84703.0
Deduct 2889 from 2921 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
320 divided by 963 is 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 84703.0
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
963 goes into 3200 3 times with a remainder of 311.
Record the quotient 3 as the next digit in the result. 
Result so far: 84703.03
If we take 2889 away from 3200, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 11:
If we divide 3110 by 963, we get 3 and a remainder of 221.
The number 3 becomes the next digit in our result. 
Result so far: 84703.033
Subtracting 2889 from 3110 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

The quotient of the division is 84703.033, and the remainder is 0.0221.
