Let's see how many times 21 fits into 563077.

Going ahead to step 1:
5 divided by 21 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 21

Moving on to step 2:
56 divided by 21 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 42 from 56 to get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 21

On to step 3:
21 goes into 143 6 times with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 126 from 143, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 21

Advancing to step 4:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 268.0
The remainder is 2 after subtracting 168 from 170.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 21

On to step 5:
When dividing 27 by 21, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 2681.0
If we subtract 21 from 27, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 21

Step 6:
The number 21 fits into 67 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 26813.0
Subtract 63 from 67 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 21, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 26813.1
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 26813.19
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 26813.19
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
21 goes into 100 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 26813.1904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 26813.19047
If we subtract 147 from 160, 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.

Going ahead to step 12:
130 divided by 21 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 26813.190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
When dividing 40 by 21, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 26813.1904761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
190 divided by 21 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 26813.19047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 26813.19047619, with a leftover of 1e-09.
