We divide 565352 by 21
We want to figure out the number of times 565352 can be divided by 21.

Step 1:
When dividing 5 by 21, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 21

Advancing to step 2:
21 goes into 56 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 42 away from 56, we end up with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 21

Moving on to step 3:
21 goes into 145 6 times with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 126 from 145 leaves us with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 21

Advancing to step 4:
When dividing 193 by 21, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 269.0
The remainder is 4 after subtracting 189 from 193.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 21

On to step 5:
When dividing 45 by 21, we get 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2692.0
Subtract 42 from 45 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 21

On to step 6:
21 can be fit into 32 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 26921.0
Subtract 21 from 32 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
110 divided by 21 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 26921.5
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
21 can be fit into 50 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 26921.52
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
If we divide 80 by 21, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 26921.523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
21 goes into 170 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 26921.5238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 26921.5238
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 26921.523809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
21 goes into 110 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 26921.5238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 26921.52380952
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 26921.52380952, with a leftover of 8e-09.
