We look at the division of 199866 by 54 
We want to figure out the number of times 199866 can be divided by 54.

Going ahead to step 1:
54 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 54

Moving on to step 2:
When dividing 19 by 54, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 54

Moving on to step 3:
54 can be fit into 199 3 times, resulting in a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 37 after subtracting 162 from 199.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 54

Step 4:
If we divide 378 by 54, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 378 from 378 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 54

Going ahead to step 5:
When dividing 6 by 54, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 370.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 54

On to step 6:
54 can be fit into 66 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 3701.0
Deduct 54 from 66 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
54 goes into 120 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3701.2
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
54 can be fit into 120 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 3701.22
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 3701.22, with a leftover of 0.012.
