We look at the division of 399185 by 7 
Let's see how many times 7 fits into 399185.

Moving on to step 1:
3 divided by 7 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 7

Going ahead to step 2:
The number 7 fits into 39 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 35 from 39 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 7

Going ahead to step 3:
7 goes into 49 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Deduct 49 from 49 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 7

Moving on to step 4:
If we divide 1 by 7, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 570.0
If we take 0 away from 1, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 7

Advancing to step 5:
If we divide 18 by 7, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 5702.0
If we subtract 14 from 18, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 7

Let's proceed to step 6:
7 goes into 45 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 57026.0
If we subtract 42 from 45, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 57026.4
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 57026.42
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
If we divide 60 by 7, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 57026.428
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
40 divided by 7 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 57026.4285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 57026.42857
If we subtract 49 from 50, we get 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 12:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 57026.428571
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 57026.4285714
Deduct 28 from 30 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 14:
When dividing 20 by 7, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 57026.42857142
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 57026.42857142 with a remainder of 6e-09.
