We look at the division of 19908 by 85 
We're looking to find how many times 85 goes into 19908.

Going ahead to step 1:
85 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 85

Moving on to step 2:
If we divide 19 by 85, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 85

Going ahead to step 3:
85 goes into 199 2 times with a remainder of 29.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 170 from 199 and we're left with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 85

Moving on to step 4:
85 can be fit into 290 3 times, resulting in a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 255 from 290 leaves us with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 85

On to step 5:
When dividing 358 by 85, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 234.0
If we subtract 340 from 358, we get 18.
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 6:
When dividing 180 by 85, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 234.2
Subtract 170 from 180 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 234.21
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
If we divide 150 by 85, we get 1 and a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 234.211
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 234.211 with a remainder of 0.0065.
