We're dividing 220675 by 78 
The aim is to understand the frequency of 78 in 220675.

On to step 1:
78 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 78

Going ahead to step 2:
78 goes into 22 0 times with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 78

Moving on to step 3:
78 goes into 220 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 156 from 220 to get 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 78

Moving on to step 4:
If we divide 646 by 78, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 624 away from 646, we end up with 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 78

Moving on to step 5:
If we divide 227 by 78, we get 2 and a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 282.0
If we take 156 away from 227, we end up with 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 78

Let's proceed to step 6:
When dividing 715 by 78, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 2829.0
The remainder is 13 after subtracting 702 from 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
The number 78 fits into 130 1 times, leaving a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 2829.1
Subtracting 78 from 130 leaves us 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:
The number 78 fits into 520 6 times, leaving a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 2829.16
Deduct 468 from 520 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 9:
78 can be fit into 520 6 times, resulting in a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 2829.166
Deduct 468 from 520 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.

The quotient of the division is 2829.166, and the remainder is 0.0052.
