Let's divide 83975 by 86
We want to figure out the number of times 83975 can be divided by 86.

Step 1:
86 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 86

Moving on to step 2:
86 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 86

Step 3:
When dividing 839 by 86, we get 9 with a remainder of 65.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 774 from 839 to get 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 86

Advancing to step 4:
The number 86 fits into 657 7 times, leaving a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
The remainder is 55 after subtracting 602 from 657.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 86

Step 5:
If we divide 555 by 86, we get 6 and a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 976.0
If we subtract 516 from 555, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 6:
86 can be fit into 390 4 times, resulting in a remainder of 46.
The next digit of our result is 4. 
Result so far: 976.4
If we subtract 344 from 390, we 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.

On to step 7:
The number 86 fits into 460 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 976.45
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.

Advancing to step 8:
86 goes into 300 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 976.453
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 976.4534
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
If we divide 760 by 86, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 976.45348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
86 goes into 720 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 976.453488
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 976.453488 with a remainder of 3.2e-06.
