205120 ÷ 86 
Our goal is to divide 205120 by 86.

Going ahead to step 1:
If we divide 2 by 86, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 86

Moving on to step 2:
86 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 86

Advancing to step 3:
If we divide 205 by 86, we get 2 and a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 33 after subtracting 172 from 205.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 86

On to step 4:
The number 86 fits into 331 3 times, leaving a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 258 away from 331, we end up with 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 86

Moving on to step 5:
When dividing 732 by 86, we get 8 with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 238.0
Subtracting 688 from 732 leaves us with 44.
Grab the next digit (0) from the dividend, add it to 44, then carry on: 440 / 86

Going ahead to step 6:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 2385.0
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
When dividing 100 by 86, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 2385.1
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
86 goes into 140 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 2385.11
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 2385.11 with a remainder of 0.054.
