We look at the division of 438840 by 57 
Let's see how many times 57 fits into 438840.

Moving on to step 1:
The number 57 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 57

On to step 2:
If we divide 43 by 57, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 57

On to step 3:
The number 57 fits into 438 7 times, leaving a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 39 after subtracting 399 from 438.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 57

On to step 4:
57 can be fit into 398 6 times, resulting in a remainder of 56.
The next digit of our result is 6. 
Result so far: 76.0
The remainder is 56 after subtracting 342 from 398.
Take the next digit (4) from the dividend and append it to 56, then repeat: 564 / 57

Step 5:
If we divide 564 by 57, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 769.0
If we take 513 away from 564, we end up with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 57

Advancing to step 6:
When dividing 510 by 57, we get 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 7698.0
Subtract 456 from 510 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
If we divide 540 by 57, we get 9 and a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 7698.9
Deduct 513 from 540 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
270 divided by 57 is 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 7698.94
Subtracting 228 from 270 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
The number 57 fits into 420 7 times, leaving a remainder of 21.
The next digit of our result is 7. 
Result so far: 7698.947
Subtract 399 from 420 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
57 can be fit into 210 3 times, resulting in a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 7698.9473
The remainder is 39 after subtracting 171 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
57 goes into 390 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 7698.94736
Subtract 342 from 390 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
57 goes into 480 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 7698.947368
The remainder is 24 after subtracting 456 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
When dividing 240 by 57, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 7698.9473684
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
57 can be fit into 120 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 7698.94736842
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 7698.94736842 with a remaining 6e-09.
