Let's divide 338129 by 86
We want to figure out the number of times 338129 can be divided by 86.

Let's proceed to step 1:
3 divided by 86 is 0 with 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.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 86

Going ahead to step 2:
86 goes into 33 0 times with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 86

Step 3:
If we divide 338 by 86, we get 3 and a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 80 after subtracting 258 from 338.
Take the next digit (1) from the dividend and append it to 80, then repeat: 801 / 86

Moving on to step 4:
If we divide 801 by 86, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 774 from 801, we get 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 86

Advancing to step 5:
86 goes into 272 3 times with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 393.0
Subtract 258 from 272 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 86

Moving on to step 6:
86 goes into 149 1 times with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 3931.0
The remainder is 63 after subtracting 86 from 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
The number 86 fits into 630 7 times, leaving a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 3931.7
If we subtract 602 from 630, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 3931.73
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
220 divided by 86 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 3931.732
Deduct 172 from 220 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
480 divided by 86 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 3931.7325
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
86 goes into 500 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 3931.73255
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 3931.73255 with a balance of 7e-05.
