We're dividing 13092077 by 621 
Let's see how many times 621 fits into 13092077.

Going ahead to step 1:
If we divide 1 by 621, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 621

Going ahead to step 2:
The number 621 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 621

Let's proceed to step 3:
130 divided by 621 is 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 130 and we're left with 130.
Grab the next digit (9) from the dividend, add it to 130, then carry on: 1309 / 621

On to step 4:
1309 divided by 621 is 2 with a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1242 from 1309 to get 67.
Grab the next digit (2) from the dividend, add it to 67, then carry on: 672 / 621

Let's proceed to step 5:
When dividing 672 by 621, we get 1 with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 621 from 672 leaves us with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 621

Let's proceed to step 6:
621 can be fit into 510 0 times, resulting in a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 210.0
Subtract 0 from 510 to get 510.
Fetch the next digit (7) from the dividend, attach it to 510 and continue: 5107 / 621

Let's proceed to step 7:
If we divide 5107 by 621, we get 8 and a remainder of 139.
The next digit of our result is 8. 
Result so far: 2108.0
The remainder is 139 after subtracting 4968 from 5107.
Bring next digit (7) of the dividend behind the 139 and repeat the process: 1397 / 621

On to step 8:
If we divide 1397 by 621, we get 2 and a remainder of 155.
Put 2 as the next digit of the answer. 
Result so far: 21082.0
The remainder is 155 after subtracting 1242 from 1397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 9:
When dividing 1550 by 621, we get 2 with a remainder of 308.
The next digit of our result is 2. 
Result so far: 21082.2
If we take 1242 away from 1550, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 10:
The number 621 fits into 3080 4 times, leaving a remainder of 596.
The number 4 becomes the next digit in our result. 
Result so far: 21082.24
Subtracting 2484 from 3080 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 11:
The number 621 fits into 5960 9 times, leaving a remainder of 371.
Use 9 as the next digit of our solution. 
Result so far: 21082.249
Subtracting 5589 from 5960 leaves us with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Going ahead to step 12:
3710 divided by 621 is 5 with a remainder of 605.
Use 5 as the next digit of our solution. 
Result so far: 21082.2495
The remainder is 605 after subtracting 3105 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 13:
The number 621 fits into 6050 9 times, leaving a remainder of 461.
Use 9 as the next digit of our solution. 
Result so far: 21082.24959
If we take 5589 away from 6050, we end up with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Moving on to step 14:
621 goes into 4610 7 times with a remainder of 263.
Write down 7 as next digit of the result. 
Result so far: 21082.249597
Subtract 4347 from 4610 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 15:
If we divide 2630 by 621, we get 4 and a remainder of 146.
The next digit of our result is 4. 
Result so far: 21082.2495974
If we subtract 2484 from 2630, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 16:
If we divide 1460 by 621, we get 2 and a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 21082.24959742
Deduct 1242 from 1460 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final result is 21082.24959742 with a remainder of 2.18e-07.
