We look at the division of 375612 by 86 
Let's see how many times 86 fits into 375612.

Step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 86

Let's proceed to step 2:
If we divide 37 by 86, we get 0 and a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 86

Advancing to step 3:
375 divided by 86 is 4 with a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 344 from 375, we get 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 86

Advancing to step 4:
86 can be fit into 316 3 times, resulting in a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 58 after subtracting 258 from 316.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 86

Let's proceed to step 5:
If we divide 581 by 86, we get 6 and a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 436.0
If we subtract 516 from 581, we get 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 86

On to step 6:
652 divided by 86 is 7 with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 4367.0
Subtract 602 from 652 to get 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 7:
When dividing 500 by 86, we get 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 4367.5
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead 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: 4367.58
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.

Step 9:
When dividing 120 by 86, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 4367.581
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
The number 86 fits into 340 3 times, leaving a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 4367.5813
Subtracting 258 from 340 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
If we divide 820 by 86, we get 9 and a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 4367.58139
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
460 divided by 86 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 4367.581395
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
When dividing 300 by 86, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 4367.5813953
Subtracting 258 from 300 leaves us with 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:
86 goes into 420 4 times with a remainder of 76.
The next digit of our result is 4. 
Result so far: 4367.58139534
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.

The final result is 4367.58139534 with a remainder of 7.6e-08.
