We look at the division of 607231 by 78 
The aim is to understand the frequency of 78 in 607231.

Moving on to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 78

On to step 2:
60 divided by 78 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 78

On to step 3:
When dividing 607 by 78, we get 7 with a remainder of 61.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 546 from 607, we get 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 78

Advancing to step 4:
If we divide 612 by 78, we get 7 and a remainder of 66.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we subtract 546 from 612, we get 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 78

Going ahead to step 5:
663 divided by 78 is 8 with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 778.0
If we subtract 624 from 663, we get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 78

Let's proceed to step 6:
When dividing 391 by 78, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 7785.0
The remainder is 1 after subtracting 390 from 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 78, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 7785.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 7785.01
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
When dividing 220 by 78, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 7785.012
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
If we divide 640 by 78, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7785.0128
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 7785.01282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
When dividing 40 by 78, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7785.01282
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
The number 78 fits into 400 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 7785.0128205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
If we divide 100 by 78, we get 1 and a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 7785.01282051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 7785.01282051, and the remainder is 2.2e-08.
