We're dividing 821161 by 1 
We want to figure out the number of times 821161 can be divided by 1.

On to step 1:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 8 from 8 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Step 2:
When dividing 2 by 1, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtract 2 from 2 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Moving on to step 3:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 821.0
Deduct 1 from 1 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Advancing to step 4:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 8211.0
The remainder is 0 after subtracting 1 from 1.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Going ahead to step 5:
If we divide 6 by 1, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 82116.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

On to step 6:
1 divided by 1 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 821161.0
Subtracting 1 from 1 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.

On to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 821161.0
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.

Moving on to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 821161.0
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.

After the division, we end up with 821161.0 and a remainder of 0.0.
