We look at the division of 621808 by 57 
Our goal is to divide 621808 by 57.

Step 1:
When dividing 6 by 57, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 57

Step 2:
The number 57 fits into 62 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 57 from 62 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 57

Step 3:
When dividing 51 by 57, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 57

Let's proceed to step 4:
When dividing 518 by 57, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 109.0
The remainder is 5 after subtracting 513 from 518.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 57

Going ahead to step 5:
If we divide 50 by 57, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1090.0
The remainder is 50 after subtracting 0 from 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 57

Advancing to step 6:
57 can be fit into 508 8 times, resulting in a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 10908.0
Subtract 456 from 508 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
520 divided by 57 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 10908.9
The remainder is 7 after subtracting 513 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
The number 57 fits into 70 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 10908.91
If we subtract 57 from 70, 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.

Let's proceed to step 9:
The number 57 fits into 130 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 10908.912
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
160 divided by 57 is 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 10908.9122
The remainder is 46 after subtracting 114 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 10908.9122, with a leftover of 0.00046.
