We look at the division of 780198 by 54 
Let's see how many times 54 fits into 780198.

Advancing to step 1:
When dividing 7 by 54, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 54

Moving on to step 2:
When dividing 78 by 54, we get 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 54 from 78 and we're left with 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 54

Advancing to step 3:
When dividing 240 by 54, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 216 from 240, we get 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 54

Step 4:
54 can be fit into 241 4 times, resulting in a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 144.0
The remainder is 25 after subtracting 216 from 241.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 54

Going ahead to step 5:
The number 54 fits into 259 4 times, leaving a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 1444.0
The remainder is 43 after subtracting 216 from 259.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 54

Going ahead to step 6:
The number 54 fits into 438 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 14448.0
If we take 432 away from 438, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
The number 54 fits into 60 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 14448.1
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 54, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 14448.11
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 14448.11, with a leftover of 0.006.
