We divide 621661 by 57
We're looking to find how many times 57 goes into 621661.

On to step 1:
When dividing 6 by 57, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 57

On to step 2:
When dividing 62 by 57, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 57 from 62 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 57

On to step 3:
If we divide 51 by 57, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 57

Let's proceed to step 4:
When dividing 516 by 57, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 109.0
Deduct 513 from 516 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 57

On to step 5:
When dividing 36 by 57, we get 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 1090.0
If we take 0 away from 36, we end up with 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 57

Moving on to step 6:
When dividing 361 by 57, we get 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 10906.0
Subtract 342 from 361 to get 19.
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 7:
57 goes into 190 3 times with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 10906.3
Subtracting 171 from 190 leaves us 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.

Going ahead to step 8:
If we divide 190 by 57, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 10906.33
The remainder is 19 after subtracting 171 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 10906.33 and a remainder of 0.019.
