399431 ÷ 52 
We want to divide 399431 by 52.

Going ahead to step 1:
52 can be fit into 3 0 times, resulting in 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.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 52

Moving on to step 2:
52 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 52

Moving on to step 3:
399 divided by 52 is 7 with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 364 away from 399, we end up with 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 52

Step 4:
The number 52 fits into 354 6 times, leaving a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Deduct 312 from 354 and we're left with 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 52

Step 5:
52 goes into 423 8 times with a remainder of 7.
The next digit of our result is 8. 
Result so far: 768.0
If we subtract 416 from 423, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 52

Let's proceed to step 6:
52 can be fit into 71 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 7681.0
Deduct 52 from 71 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 52 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 7681.3
Subtracting 156 from 190 leaves us 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.

Step 8:
The number 52 fits into 340 6 times, leaving a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 7681.36
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
52 goes into 280 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 7681.365
Subtracting 260 from 280 leaves us 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.

Going ahead to step 10:
52 goes into 200 3 times with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 7681.3653
If we take 156 away from 200, we end up 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.

Let's proceed to step 11:
52 can be fit into 440 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 7681.36538
Subtracting 416 from 440 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
240 divided by 52 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7681.365384
If we take 208 away from 240, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
52 can be fit into 320 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 7681.3653846
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
80 divided by 52 is 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 7681.36538461
If we take 52 away from 80, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 7681.36538461 with a remaining 2.8e-08.
