Let's divide 375291 by 86
We want to figure out the number of times 375291 can be divided by 86.

Going ahead to step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 86

Step 2:
37 divided by 86 is 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 86

Advancing to step 3:
If we divide 375 by 86, we get 4 and a remainder of 31.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 344 from 375, we get 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 86

Step 4:
312 divided by 86 is 3 with a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 54 after subtracting 258 from 312.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 86

Going ahead to step 5:
86 can be fit into 549 6 times, resulting in a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 436.0
Subtracting 516 from 549 leaves us with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 86

Moving on to step 6:
86 can be fit into 331 3 times, resulting in a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 4363.0
Subtract 258 from 331 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
If we divide 730 by 86, we get 8 and a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 4363.8
If we take 688 away from 730, we end up 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.

Going ahead to step 8:
86 goes into 420 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 4363.84
Deduct 344 from 420 and we're left 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.

Step 9:
86 can be fit into 760 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 4363.848
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
86 can be fit into 720 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 4363.8488
Subtracting 688 from 720 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 4363.8488 and a remainder of 0.00032.
