We look at the division of 203151 by 86 
We're looking to find how many times 86 goes into 203151.

Let's proceed to step 1:
The number 86 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 86

Moving on to step 2:
If we divide 20 by 86, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 86

Moving on to step 3:
86 goes into 203 2 times with a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 31 after subtracting 172 from 203.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 86

Going ahead to step 4:
311 divided by 86 is 3 with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 258 from 311 to get 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 86

Going ahead to step 5:
86 goes into 535 6 times with a remainder of 19.
The next digit of our result is 6. 
Result so far: 236.0
If we take 516 away from 535, we end up with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 86

Going ahead to step 6:
When dividing 191 by 86, we get 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2362.0
If we take 172 away from 191, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
86 can be fit into 190 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2362.2
The remainder is 18 after subtracting 172 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
When dividing 180 by 86, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2362.22
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 2362.22 and a remainder of 0.008.
