Let's divide 21035273 by 875
We want to figure out the number of times 21035273 can be divided by 875.

Advancing to step 1:
875 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 875

Step 2:
When dividing 21 by 875, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 875

Moving on to step 3:
210 divided by 875 is 0 with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Grab the next digit (3) from the dividend, add it to 210, then carry on: 2103 / 875

Going ahead to step 4:
When dividing 2103 by 875, we get 2 with a remainder of 353.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1750 from 2103, we get 353.
Bring next digit (5) of the dividend behind the 353 and repeat the process: 3535 / 875

Advancing to step 5:
875 goes into 3535 4 times with a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtracting 3500 from 3535 leaves us with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 875

Moving on to step 6:
If we divide 352 by 875, we get 0 and a remainder of 352.
Put 0 as the next digit of the answer. 
Result so far: 240.0
Subtracting 0 from 352 leaves us with 352.
Grab the next digit (7) from the dividend, add it to 352, then carry on: 3527 / 875

Advancing to step 7:
875 can be fit into 3527 4 times, resulting in a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 2404.0
If we take 3500 away from 3527, we end up with 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 875

On to step 8:
When dividing 273 by 875, we get 0 with a remainder of 273.
Record the quotient 0 as the next digit in the result. 
Result so far: 24040.0
Subtract 0 from 273 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Advancing to step 9:
The number 875 fits into 2730 3 times, leaving a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 24040.3
Subtract 2625 from 2730 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 10:
1050 divided by 875 is 1 with a remainder of 175.
The next digit of our result is 1. 
Result so far: 24040.31
Subtracting 875 from 1050 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 11:
If we divide 1750 by 875, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 24040.312
Deduct 1750 from 1750 and we're left 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.

Moving on to step 12:
The number 875 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 24040.312
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.

On to step 13:
875 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 24040.312
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 outcome is 24040.312, with a leftover of 0.0.
