We look at the division of 198354 by 86 
Our goal is to divide 198354 by 86.

Advancing to step 1:
When dividing 1 by 86, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 86

Going ahead to step 2:
86 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 86

Going ahead to step 3:
86 can be fit into 198 2 times, resulting in a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 172 away from 198, we end up with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 86

Let's proceed to step 4:
The number 86 fits into 263 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 258 from 263 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 86

Advancing to step 5:
86 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 230.0
The remainder is 55 after subtracting 0 from 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 86

On to step 6:
The number 86 fits into 554 6 times, leaving a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 2306.0
The remainder is 38 after subtracting 516 from 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 2306.4
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
86 goes into 360 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 2306.44
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 2306.44 with a remainder of 0.016.
