We divide 13230459 by 621
We want to divide 13230459 by 621.

Going ahead to step 1:
621 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 621

Going ahead to step 2:
If we divide 13 by 621, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 621

Going ahead to step 3:
132 divided by 621 is 0 with a remainder of 132.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 132 after subtracting 0 from 132.
Include the next digit (3) from the dividend after 132, then repeat: 1323 / 621

Moving on to step 4:
1323 divided by 621 is 2 with a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1242 from 1323, we get 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 621

Moving on to step 5:
If we divide 810 by 621, we get 1 and a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 621 away from 810, we end up with 189.
Append the next digit (4) from the dividend to 189 and continue with: 1894 / 621

Let's proceed to step 6:
1894 divided by 621 is 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 213.0
If we take 1863 away from 1894, we end up with 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 621

Step 7:
621 goes into 315 0 times with a remainder of 315.
Record the quotient 0 as the next digit in the result. 
Result so far: 2130.0
Deduct 0 from 315 and we're left with 315.
Grab the next digit (9) from the dividend, add it to 315, then carry on: 3159 / 621

On to step 8:
3159 divided by 621 is 5 with a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 21305.0
Subtract 3105 from 3159 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
When dividing 540 by 621, we get 0 with a remainder of 540.
The next digit of our result is 0. 
Result so far: 21305.0
The remainder is 540 after subtracting 0 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 10:
621 can be fit into 5400 8 times, resulting in a remainder of 432.
The next digit of our result is 8. 
Result so far: 21305.08
Deduct 4968 from 5400 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 11:
When dividing 4320 by 621, we get 6 with a remainder of 594.
The number 6 becomes the next digit in our result. 
Result so far: 21305.086
Subtracting 3726 from 4320 leaves us with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Going ahead to step 12:
5940 divided by 621 is 9 with a remainder of 351.
Put 9 as the next digit of the answer. 
Result so far: 21305.0869
Subtract 5589 from 5940 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 13:
If we divide 3510 by 621, we get 5 and a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 21305.08695
Deduct 3105 from 3510 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 14:
If we divide 4050 by 621, we get 6 and a remainder of 324.
Put 6 as the next digit of the answer. 
Result so far: 21305.086956
Subtracting 3726 from 4050 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 15:
621 goes into 3240 5 times with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 21305.0869565
Subtracting 3105 from 3240 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 16:
1350 divided by 621 is 2 with a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 21305.08695652
If we subtract 1242 from 1350, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 21305.08695652, with a leftover of 1.08e-07.
