We're dividing 54685566 by 78 
We're looking to find how many times 78 goes into 54685566.

Let's proceed to step 1:
5 divided by 78 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 78

Going ahead to step 2:
54 divided by 78 is 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 78

Step 3:
546 divided by 78 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 546 from 546, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 78

Moving on to step 4:
When dividing 8 by 78, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 78

Moving on to step 5:
85 divided by 78 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 701.0
Subtracting 78 from 85 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 78

Going ahead to step 6:
The number 78 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 7010.0
Subtract 0 from 75 to get 75.
Grab the next digit (6) from the dividend, add it to 75, then carry on: 756 / 78

Moving on to step 7:
78 goes into 756 9 times with a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 70109.0
Subtracting 702 from 756 leaves us with 54.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 78

On to step 8:
When dividing 546 by 78, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 701097.0
If we subtract 546 from 546, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
78 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 701097.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 78 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 701097.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 701097.0 with a remaining 0.0.
