We look at the division of 21568639 by 469 
We want to figure out the number of times 21568639 can be divided by 469.

Going ahead to step 1:
When dividing 2 by 469, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 469

Going ahead to step 2:
The number 469 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 469

Going ahead to step 3:
469 can be fit into 215 0 times, resulting in a remainder of 215.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 215 and we're left with 215.
Bring next digit (6) of the dividend behind the 215 and repeat the process: 2156 / 469

Going ahead to step 4:
2156 divided by 469 is 4 with a remainder of 280.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1876 away from 2156, we end up with 280.
Take the next digit (8) from the dividend and append it to 280, then repeat: 2808 / 469

Advancing to step 5:
The number 469 fits into 2808 5 times, leaving a remainder of 463.
Write down 5 as next digit of the result. 
Result so far: 45.0
Deduct 2345 from 2808 and we're left with 463.
Append the next digit (6) from the dividend to 463 and continue with: 4636 / 469

Step 6:
If we divide 4636 by 469, we get 9 and a remainder of 415.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
If we take 4221 away from 4636, we end up with 415.
Grab the next digit (3) from the dividend, add it to 415, then carry on: 4153 / 469

On to step 7:
When dividing 4153 by 469, we get 8 with a remainder of 401.
Use 8 as the next digit of our solution. 
Result so far: 4598.0
Subtracting 3752 from 4153 leaves us with 401.
Fetch the next digit (9) from the dividend, attach it to 401 and continue: 4019 / 469

Moving on to step 8:
4019 divided by 469 is 8 with a remainder of 267.
The next digit of our result is 8. 
Result so far: 45988.0
Subtract 3752 from 4019 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 9:
The number 469 fits into 2670 5 times, leaving a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 45988.5
Subtracting 2345 from 2670 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 10:
When dividing 3250 by 469, we get 6 with a remainder of 436.
Use 6 as the next digit of our solution. 
Result so far: 45988.56
If we subtract 2814 from 3250, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 11:
When dividing 4360 by 469, we get 9 with a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 45988.569
Subtract 4221 from 4360 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 12:
When dividing 1390 by 469, we get 2 with a remainder of 452.
The number 2 becomes the next digit in our result. 
Result so far: 45988.5692
The remainder is 452 after subtracting 938 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 13:
4520 divided by 469 is 9 with a remainder of 299.
The next digit of our result is 9. 
Result so far: 45988.56929
If we take 4221 away from 4520, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 14:
The number 469 fits into 2990 6 times, leaving a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 45988.569296
Subtracting 2814 from 2990 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 15:
469 goes into 1760 3 times with a remainder of 353.
Write down 3 as next digit of the result. 
Result so far: 45988.5692963
If we take 1407 away from 1760, we end up with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Step 16:
The number 469 fits into 3530 7 times, leaving a remainder of 247.
The next digit of our result is 7. 
Result so far: 45988.56929637
Subtracting 3283 from 3530 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Our division results in 45988.56929637 with a remaining 2.47e-07.
