We look at the division of 881021 by 80 
We want to figure out the number of times 881021 can be divided by 80.

Moving on to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 80

Advancing to step 2:
When dividing 88 by 80, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 80 from 88 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 80

Step 3:
When dividing 81 by 80, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 1 after subtracting 80 from 81.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 80

Step 4:
80 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: 110.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 80

Advancing to step 5:
80 goes into 102 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1101.0
Deduct 80 from 102 and we're left with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 80

Advancing to step 6:
When dividing 221 by 80, we get 2 with a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 11012.0
Subtract 160 from 221 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
610 divided by 80 is 7 with a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 11012.7
The remainder is 50 after subtracting 560 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 11012.76
Subtract 480 from 500 to 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.

Step 9:
80 goes into 200 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 11012.762
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 11012.7625
Subtract 400 from 400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11012.7625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 11012.7625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 11012.7625 with a remainder of 0.0.
