We look at the division of 635518 by 78 
Let's see how many times 78 fits into 635518.

Step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 78

Let's proceed to step 2:
78 goes into 63 0 times with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Fetch the next digit (5) from the dividend, attach it to 63 and continue: 635 / 78

Going ahead to step 3:
78 can be fit into 635 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 624 from 635 to get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 78

Let's proceed to step 4:
The number 78 fits into 115 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 81.0
If we take 78 away from 115, we end up with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 78

Advancing to step 5:
78 can be fit into 371 4 times, resulting in a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 814.0
If we take 312 away from 371, we end up with 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 78

Step 6:
When dividing 598 by 78, we get 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 8147.0
Deduct 546 from 598 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
The number 78 fits into 520 6 times, leaving a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 8147.6
If we take 468 away from 520, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
78 goes into 520 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 8147.66
If we subtract 468 from 520, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 8147.66 and a remainder of 0.052.
