552760 ÷ 21 
We want to divide 552760 by 21.

Let's proceed to step 1:
If we divide 5 by 21, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 21

Advancing to step 2:
If we divide 55 by 21, we get 2 and a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 55, we end up with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 21

Moving on to step 3:
132 divided by 21 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 26.0
If we subtract 126 from 132, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 21

On to step 4:
When dividing 67 by 21, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 263.0
The remainder is 4 after subtracting 63 from 67.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 21

Advancing to step 5:
The number 21 fits into 46 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2632.0
Subtracting 42 from 46 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 21

On to step 6:
21 goes into 40 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 26321.0
If we take 21 away from 40, we end up 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.

Let's proceed to step 7:
21 goes into 190 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 26321.9
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 26321.9
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 26321.904
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.

Step 10:
If we divide 160 by 21, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 26321.9047
Subtract 147 from 160 to 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.

Advancing to step 11:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 26321.90476
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.

Step 12:
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: 26321.904761
The remainder is 19 after subtracting 21 from 40.
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 13:
If we divide 190 by 21, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 26321.9047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
10 divided by 21 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 26321.9047619
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 26321.9047619 and a remainder of 1e-08.
