399548 divided by 57 
We're looking to find how many times 57 goes into 399548.

Step 1:
If we divide 3 by 57, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 57

Let's proceed to step 2:
The number 57 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 57

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
If we take 399 away from 399, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 57

Step 4:
5 divided by 57 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 70.0
If we take 0 away from 5, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 57

Advancing to step 5:
57 goes into 54 0 times with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 700.0
Subtracting 0 from 54 leaves us with 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 57

Going ahead to step 6:
548 divided by 57 is 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 7009.0
Subtracting 513 from 548 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
57 goes into 350 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7009.6
If we subtract 342 from 350, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
80 divided by 57 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 7009.61
If we subtract 57 from 80, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
57 goes into 230 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 7009.614
Deduct 228 from 230 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 57, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7009.614
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 57 is 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 7009.61403
Subtracting 171 from 200 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
57 can be fit into 290 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 7009.614035
If we take 285 away from 290, we end up 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.

On to step 13:
When dividing 50 by 57, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 7009.614035
Subtract 0 from 50 to 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.

Step 14:
The number 57 fits into 500 8 times, leaving a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 7009.61403508
If we subtract 456 from 500, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 7009.61403508, and the remainder is 4.4e-08.
