398181 divided by 39 
We want to figure out the number of times 398181 can be divided by 39.

Advancing to step 1:
3 divided by 39 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 39

On to step 2:
39 divided by 39 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 39 away from 39, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 39

Let's proceed to step 3:
The number 39 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 39

Moving on to step 4:
81 divided by 39 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 102.0
The remainder is 3 after subtracting 78 from 81.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 39

Going ahead to step 5:
39 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 1020.0
If we take 0 away from 38, we end up with 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 39

Step 6:
The number 39 fits into 381 9 times, leaving a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 10209.0
If we take 351 away from 381, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
The number 39 fits into 300 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 10209.7
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
270 divided by 39 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 10209.76
Subtract 234 from 270 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
If we divide 360 by 39, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 10209.769
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
If we divide 90 by 39, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 10209.7692
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
If we divide 120 by 39, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 10209.76923
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
30 divided by 39 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 10209.76923
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
300 divided by 39 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 10209.7692307
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 14:
39 goes into 270 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 10209.76923076
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 10209.76923076 with a balance of 3.6e-08.
