We look at the division of 53199168 by 78 
We're looking to find how many times 78 goes into 53199168.

Moving on to step 1:
The number 78 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 78

Moving on to step 2:
53 divided by 78 is 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 78

Moving on to step 3:
531 divided by 78 is 6 with a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 468 from 531 to get 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 78

Moving on to step 4:
78 goes into 639 8 times with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtracting 624 from 639 leaves us with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 78

Step 5:
78 can be fit into 159 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 682.0
Deduct 156 from 159 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 78

Advancing to step 6:
The number 78 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 6820.0
Subtract 0 from 31 to get 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 78

Going ahead to step 7:
If we divide 316 by 78, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 68204.0
The remainder is 4 after subtracting 312 from 316.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 78

On to step 8:
If we divide 48 by 78, we get 0 and a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 682040.0
Subtract 0 from 48 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
480 divided by 78 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 682040.6
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
The number 78 fits into 120 1 times, leaving a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 682040.61
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
78 goes into 420 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 682040.615
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
300 divided by 78 is 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 682040.6153
If we subtract 234 from 300, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 13:
78 goes into 660 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 682040.61538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
If we divide 360 by 78, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 682040.615384
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 15:
When dividing 480 by 78, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 682040.6153846
Subtract 468 from 480 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 16:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 682040.61538461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 682040.61538461, and the remainder is 4.2e-08.
