817145 divided by 57 
We want to divide 817145 by 57.

Moving on to step 1:
The number 57 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 57

On to step 2:
81 divided by 57 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 24 after subtracting 57 from 81.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 57

Going ahead to step 3:
If we divide 247 by 57, we get 4 and a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 228 from 247 and we're left with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 57

Step 4:
57 goes into 191 3 times with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 143.0
The remainder is 20 after subtracting 171 from 191.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 57

Let's proceed to step 5:
204 divided by 57 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 1433.0
If we take 171 away from 204, we end up with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 57

Advancing to step 6:
57 can be fit into 335 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 14335.0
Subtract 285 from 335 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
500 divided by 57 is 8 with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 14335.8
Subtract 456 from 500 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
440 divided by 57 is 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 14335.87
Subtracting 399 from 440 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
The number 57 fits into 410 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 14335.877
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 14335.877, with a leftover of 0.0011.
