872921 divided by 75 
Let's see how many times 75 fits into 872921.

Going ahead to step 1:
8 divided by 75 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 75

Step 2:
If we divide 87 by 75, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 75 from 87, we get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 75

Let's proceed to step 3:
When dividing 122 by 75, we get 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 75 from 122, we get 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 75

Let's proceed to step 4:
479 divided by 75 is 6 with a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we subtract 450 from 479, we get 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 75

Going ahead to step 5:
75 goes into 292 3 times with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 1163.0
If we subtract 225 from 292, we get 67.
Take the next digit (1) from the dividend and append it to 67, then repeat: 671 / 75

On to step 6:
75 goes into 671 8 times with a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 11638.0
The remainder is 71 after subtracting 600 from 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 7:
710 divided by 75 is 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 11638.9
If we subtract 675 from 710, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
If we divide 350 by 75, we get 4 and a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 11638.94
If we subtract 300 from 350, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 11638.946
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
500 divided by 75 is 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 11638.9466
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 11638.9466, and the remainder is 0.0005.
