We divide 399685 by 57
We're looking to find how many times 57 goes into 399685.

Advancing to step 1:
The number 57 fits into 3 0 times, leaving 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:
When dividing 39 by 57, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 57

Advancing to step 3:
57 goes into 399 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 0 after subtracting 399 from 399.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 57

Let's proceed to step 4:
57 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 57

Let's proceed to step 5:
57 can be fit into 68 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 701.0
If we subtract 57 from 68, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 57

On to step 6:
The number 57 fits into 115 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 7012.0
Deduct 114 from 115 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
If we divide 10 by 57, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7012.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 57, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 7012.01
If we subtract 57 from 100, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
430 divided by 57 is 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 7012.017
If we take 399 away from 430, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
The number 57 fits into 310 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 7012.0175
Subtracting 285 from 310 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
250 divided by 57 is 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 7012.01754
Subtract 228 from 250 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
57 goes into 220 3 times with a remainder of 49.
The next digit of our result is 3. 
Result so far: 7012.017543
Deduct 171 from 220 and we're left 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.

Moving on to step 13:
57 can be fit into 490 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 7012.0175438
If we take 456 away from 490, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
When dividing 340 by 57, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 7012.01754385
Deduct 285 from 340 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 7012.01754385 with a remainder of 5.5e-08.
