621769 ÷ 57 
Let's see how many times 57 fits into 621769.

Moving on to step 1:
57 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 57

Step 2:
57 can be fit into 62 1 times, resulting in 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.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 57

Moving on to step 3:
The number 57 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 57

On to step 4:
When dividing 517 by 57, we get 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 109.0
The remainder is 4 after subtracting 513 from 517.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 57

Advancing to step 5:
57 can be fit into 46 0 times, resulting in a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 1090.0
Deduct 0 from 46 and we're left with 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 57

Step 6:
When dividing 469 by 57, we get 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 10908.0
If we take 456 away from 469, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
130 divided by 57 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 10908.2
Deduct 114 from 130 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
If we divide 160 by 57, we get 2 and a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 10908.22
Deduct 114 from 160 and we're left with 46.
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 result is 10908.22 with a remainder of 0.046.
