We're dividing 811204 by 15 
We want to divide 811204 by 15.

Moving on to step 1:
8 divided by 15 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 15

Advancing to step 2:
15 goes into 81 5 times with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 75 from 81 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 15

Moving on to step 3:
When dividing 61 by 15, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 60 from 61, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 15

Step 4:
15 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 540.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 15

On to step 5:
If we divide 120 by 15, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 5408.0
Deduct 120 from 120 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 15

Step 6:
When dividing 4 by 15, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 54080.0
Deduct 0 from 4 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 15 fits into 40 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 54080.2
Subtract 30 from 40 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 54080.26
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 54080.266
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 54080.266, and the remainder is 0.001.
