We're dividing 842721 by 75 
We want to divide 842721 by 75.

Advancing to step 1:
8 divided by 75 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 75

Advancing to step 2:
The number 75 fits into 84 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 75 from 84 to get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 75

Step 3:
92 divided by 75 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 75 from 92 leaves us with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 75

Moving on to step 4:
75 can be fit into 177 2 times, resulting in a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
The remainder is 27 after subtracting 150 from 177.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 75

Advancing to step 5:
When dividing 272 by 75, we get 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 1123.0
Deduct 225 from 272 and we're left with 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 75

Step 6:
471 divided by 75 is 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 11236.0
Subtract 450 from 471 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
When dividing 210 by 75, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 11236.2
If we take 150 away from 210, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
75 can be fit into 600 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 11236.28
If we take 600 away from 600, 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 9:
0 divided by 75 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11236.28
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 10:
75 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11236.28
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.

The quotient of the division is 11236.28, and the remainder is 0.0.
