We're dividing 21220576 by 813 
We're looking to find how many times 813 goes into 21220576.

Moving on to step 1:
813 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 813

Going ahead to step 2:
If we divide 21 by 813, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 813

Moving on to step 3:
212 divided by 813 is 0 with a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Fetch the next digit (2) from the dividend, attach it to 212 and continue: 2122 / 813

Going ahead to step 4:
813 can be fit into 2122 2 times, resulting in a remainder of 496.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1626 from 2122 and we're left with 496.
Bring next digit (0) of the dividend behind the 496 and repeat the process: 4960 / 813

On to step 5:
If we divide 4960 by 813, we get 6 and a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtract 4878 from 4960 to get 82.
Include the next digit (5) from the dividend after 82, then repeat: 825 / 813

On to step 6:
The number 813 fits into 825 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 261.0
If we take 813 away from 825, we end up with 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 813

Going ahead to step 7:
When dividing 127 by 813, we get 0 with a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 2610.0
If we subtract 0 from 127, we get 127.
Fetch the next digit (6) from the dividend, attach it to 127 and continue: 1276 / 813

Step 8:
If we divide 1276 by 813, we get 1 and a remainder of 463.
Write down 1 as next digit of the result. 
Result so far: 26101.0
The remainder is 463 after subtracting 813 from 1276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Moving on to step 9:
If we divide 4630 by 813, we get 5 and a remainder of 565.
The next digit of our result is 5. 
Result so far: 26101.5
Subtracting 4065 from 4630 leaves us with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Let's proceed to step 10:
If we divide 5650 by 813, we get 6 and a remainder of 772.
Record the quotient 6 as the next digit in the result. 
Result so far: 26101.56
Subtracting 4878 from 5650 leaves us with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Let's proceed to step 11:
When dividing 7720 by 813, we get 9 with a remainder of 403.
Record the quotient 9 as the next digit in the result. 
Result so far: 26101.569
Subtract 7317 from 7720 to get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Advancing to step 12:
The number 813 fits into 4030 4 times, leaving a remainder of 778.
Write down 4 as next digit of the result. 
Result so far: 26101.5694
If we take 3252 away from 4030, we end up with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Advancing to step 13:
When dividing 7780 by 813, we get 9 with a remainder of 463.
Write down 9 as next digit of the result. 
Result so far: 26101.56949
Subtracting 7317 from 7780 leaves us with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Moving on to step 14:
813 goes into 4630 5 times with a remainder of 565.
Write down 5 as next digit of the result. 
Result so far: 26101.569495
Deduct 4065 from 4630 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Moving on to step 15:
813 goes into 5650 6 times with a remainder of 772.
Write down 6 as next digit of the result. 
Result so far: 26101.5694956
If we subtract 4878 from 5650, we get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Advancing to step 16:
813 can be fit into 7720 9 times, resulting in a remainder of 403.
Write down 9 as next digit of the result. 
Result so far: 26101.56949569
If we subtract 7317 from 7720, we get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

The final outcome is 26101.56949569, with a leftover of 4.03e-07.
