We're dividing 629217 by 78 
The aim is to understand the frequency of 78 in 629217.

Going ahead to step 1:
78 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 78

On to step 2:
78 can be fit into 62 0 times, resulting in a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 78

Going ahead to step 3:
629 divided by 78 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 5 after subtracting 624 from 629.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 78

Going ahead to step 4:
When dividing 52 by 78, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 78

Moving on to step 5:
When dividing 521 by 78, we get 6 with a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 806.0
If we take 468 away from 521, we end up with 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 78

Step 6:
537 divided by 78 is 6 with a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 8066.0
Deduct 468 from 537 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
690 divided by 78 is 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 8066.8
Deduct 624 from 690 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
660 divided by 78 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 8066.88
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 8066.88 with a balance of 0.036.
