21488709 divided by 872 
We want to figure out the number of times 21488709 can be divided by 872.

Going ahead to step 1:
If we divide 2 by 872, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 872

On to step 2:
If we divide 21 by 872, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 872

Going ahead to step 3:
872 goes into 214 0 times with a remainder of 214.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 214 to get 214.
Bring next digit (8) of the dividend behind the 214 and repeat the process: 2148 / 872

Let's proceed to step 4:
872 goes into 2148 2 times with a remainder of 404.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1744 from 2148, we get 404.
Bring next digit (8) of the dividend behind the 404 and repeat the process: 4048 / 872

Advancing to step 5:
When dividing 4048 by 872, we get 4 with a remainder of 560.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 3488 from 4048, we get 560.
Grab the next digit (7) from the dividend, add it to 560, then carry on: 5607 / 872

Let's proceed to step 6:
When dividing 5607 by 872, we get 6 with a remainder of 375.
Write down 6 as next digit of the result. 
Result so far: 246.0
Subtracting 5232 from 5607 leaves us with 375.
Include the next digit (0) from the dividend after 375, then repeat: 3750 / 872

Let's proceed to step 7:
If we divide 3750 by 872, we get 4 and a remainder of 262.
Put 4 as the next digit of the answer. 
Result so far: 2464.0
Subtracting 3488 from 3750 leaves us with 262.
Append the next digit (9) from the dividend to 262 and continue with: 2629 / 872

Step 8:
The number 872 fits into 2629 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 24643.0
If we subtract 2616 from 2629, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
130 divided by 872 is 0 with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 24643.0
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
872 can be fit into 1300 1 times, resulting in a remainder of 428.
Record the quotient 1 as the next digit in the result. 
Result so far: 24643.01
If we subtract 872 from 1300, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 11:
If we divide 4280 by 872, we get 4 and a remainder of 792.
Record the quotient 4 as the next digit in the result. 
Result so far: 24643.014
Subtracting 3488 from 4280 leaves us with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Let's proceed to step 12:
The number 872 fits into 7920 9 times, leaving a remainder of 72.
Write down 9 as next digit of the result. 
Result so far: 24643.0149
If we take 7848 away from 7920, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
The number 872 fits into 720 0 times, leaving a remainder of 720.
Record the quotient 0 as the next digit in the result. 
Result so far: 24643.0149
If we subtract 0 from 720, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 14:
872 goes into 7200 8 times with a remainder of 224.
Use 8 as the next digit of our solution. 
Result so far: 24643.014908
Subtract 6976 from 7200 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 15:
2240 divided by 872 is 2 with a remainder of 496.
The number 2 becomes the next digit in our result. 
Result so far: 24643.0149082
If we subtract 1744 from 2240, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 16:
4960 divided by 872 is 5 with a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 24643.01490825
Subtract 4360 from 4960 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 24643.01490825 with a remaining 6e-07.
