We look at the division of 821120 by 8 
Let's see how many times 8 fits into 821120.

Going ahead to step 1:
The number 8 fits into 8 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 8 from 8 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 8

On to step 2:
When dividing 2 by 8, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 8

On to step 3:
8 can be fit into 21 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we take 16 away from 21, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 8

Moving on to step 4:
When dividing 51 by 8, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 1026.0
If we take 48 away from 51, we end up with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 8

Going ahead to step 5:
8 can be fit into 32 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 10264.0
Deduct 32 from 32 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 8

Let's proceed to step 6:
If we divide 0 by 8, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 102640.0
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.

Advancing to step 7:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 102640.0
If we subtract 0 from 0, we 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 8:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 102640.0
Subtracting 0 from 0 leaves us 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.

The final result is 102640.0 with a remainder of 0.0.
