We divide 390512 by 57
Let's see how many times 57 fits into 390512.

On to step 1:
3 divided by 57 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 57

Advancing to step 2:
39 divided by 57 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 57

Step 3:
When dividing 390 by 57, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 342 from 390 and we're left with 48.
Grab the next digit (5) from the dividend, add it to 48, then carry on: 485 / 57

Moving on to step 4:
57 goes into 485 8 times with a remainder of 29.
The next digit of our result is 8. 
Result so far: 68.0
The remainder is 29 after subtracting 456 from 485.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 57

Advancing to step 5:
The number 57 fits into 291 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 685.0
Deduct 285 from 291 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 57

Step 6:
57 goes into 62 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 6851.0
Subtracting 57 from 62 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 57 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 6851.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
When dividing 500 by 57, we get 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 6851.08
Subtracting 456 from 500 leaves us 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.

Advancing to step 9:
If we divide 440 by 57, we get 7 and a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 6851.087
If we take 399 away from 440, we end up 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.

Let's proceed to step 10:
The number 57 fits into 410 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 6851.0877
The remainder is 11 after subtracting 399 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 6851.0877, and the remainder is 0.00011.
