439064 ÷ 57 
We want to figure out the number of times 439064 can be divided by 57.

Going ahead to step 1:
The number 57 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 57

On to step 2:
57 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 57

Advancing to step 3:
The number 57 fits into 439 7 times, leaving a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 399 from 439, we get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 57

Moving on to step 4:
When dividing 400 by 57, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtract 399 from 400 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 57

On to step 5:
When dividing 16 by 57, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 770.0
Subtract 0 from 16 to get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 57

Moving on to step 6:
When dividing 164 by 57, we get 2 with a remainder of 50.
The next digit of our result is 2. 
Result so far: 7702.0
If we subtract 114 from 164, we 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:
57 goes into 500 8 times with a remainder of 44.
The next digit of our result is 8. 
Result so far: 7702.8
Deduct 456 from 500 and we're left with 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:
The number 57 fits into 440 7 times, leaving a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 7702.87
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.

Going ahead to step 9:
If we divide 410 by 57, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 7702.877
Subtracting 399 from 410 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 7702.877 with a balance of 0.0011.
