Let's divide 456391 by 57
We want to figure out the number of times 456391 can be divided by 57.

Step 1:
57 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 57

On to step 2:
57 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 57

Let's proceed to step 3:
57 can be fit into 456 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 456 away from 456, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 57

Advancing to step 4:
57 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 57

On to step 5:
The number 57 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 800.0
If we subtract 0 from 39, we get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 57

On to step 6:
57 can be fit into 391 6 times, resulting in a remainder of 49.
Record the quotient 6 as the next digit in the result. 
Result so far: 8006.0
Subtracting 342 from 391 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
57 goes into 490 8 times with a remainder of 34.
The next digit of our result is 8. 
Result so far: 8006.8
The remainder is 34 after subtracting 456 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
The number 57 fits into 340 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 8006.85
Subtract 285 from 340 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
When dividing 550 by 57, we get 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 8006.859
Subtract 513 from 550 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 10:
370 divided by 57 is 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 8006.8596
Deduct 342 from 370 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
When dividing 280 by 57, we get 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 8006.85964
If we take 228 away from 280, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
If we divide 520 by 57, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 8006.859649
Subtracting 513 from 520 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
The number 57 fits into 70 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 8006.8596491
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.

Step 14:
The number 57 fits into 130 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 8006.85964912
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.

In conclusion, the division gives 8006.85964912 with a balance of 1.6e-08.
