We look at the division of 54066120 by 798 
We want to figure out the number of times 54066120 can be divided by 798.

On to step 1:
When dividing 5 by 798, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 798

Moving on to step 2:
798 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 798

Let's proceed to step 3:
When dividing 540 by 798, we get 0 with a remainder of 540.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 540 and we're left with 540.
Take the next digit (6) from the dividend and append it to 540, then repeat: 5406 / 798

Advancing to step 4:
If we divide 5406 by 798, we get 6 and a remainder of 618.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 4788 from 5406 and we're left with 618.
Include the next digit (6) from the dividend after 618, then repeat: 6186 / 798

On to step 5:
When dividing 6186 by 798, we get 7 with a remainder of 600.
The next digit of our result is 7. 
Result so far: 67.0
If we subtract 5586 from 6186, we get 600.
Bring next digit (1) of the dividend behind the 600 and repeat the process: 6001 / 798

Let's proceed to step 6:
798 can be fit into 6001 7 times, resulting in a remainder of 415.
Use 7 as the next digit of our solution. 
Result so far: 677.0
Subtracting 5586 from 6001 leaves us with 415.
Bring next digit (2) of the dividend behind the 415 and repeat the process: 4152 / 798

Step 7:
4152 divided by 798 is 5 with a remainder of 162.
The number 5 becomes the next digit in our result. 
Result so far: 6775.0
Subtracting 3990 from 4152 leaves us with 162.
Fetch the next digit (0) from the dividend, attach it to 162 and continue: 1620 / 798

On to step 8:
When dividing 1620 by 798, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 67752.0
Deduct 1596 from 1620 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
798 goes into 240 0 times with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 67752.0
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
798 can be fit into 2400 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 67752.03
The remainder is 6 after subtracting 2394 from 2400.
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 11:
798 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 67752.03
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
The number 798 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 67752.03
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 67752.03 with a remainder of 0.006.
