We're dividing 355875 by 86 
We want to figure out the number of times 355875 can be divided by 86.

Going ahead to step 1:
3 divided by 86 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 86

On to step 2:
The number 86 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 86

Moving on to step 3:
When dividing 355 by 86, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 344 from 355 to get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 86

Moving on to step 4:
86 goes into 118 1 times with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
The remainder is 32 after subtracting 86 from 118.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 86

Advancing to step 5:
When dividing 327 by 86, we get 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 413.0
Subtracting 258 from 327 leaves us with 69.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 86

Moving on to step 6:
86 can be fit into 695 8 times, resulting in a remainder of 7.
The next digit of our result is 8. 
Result so far: 4138.0
Subtracting 688 from 695 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 86 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 4138.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
86 can be fit into 700 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 4138.08
Subtracting 688 from 700 leaves us 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.

Going ahead to step 9:
86 goes into 120 1 times with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 4138.081
If we take 86 away from 120, we end up 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.

Moving on to step 10:
86 can be fit into 340 3 times, resulting in a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 4138.0813
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 11:
When dividing 820 by 86, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 4138.08139
Subtract 774 from 820 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
460 divided by 86 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 4138.081395
Subtracting 430 from 460 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.

Going ahead to step 13:
86 can be fit into 300 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 4138.0813953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 14:
When dividing 420 by 86, we get 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 4138.08139534
If we take 344 away from 420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 4138.08139534 with a remaining 7.6e-08.
