We're dividing 70107033 by 78 
The aim is to understand the frequency of 78 in 70107033.

Step 1:
7 divided by 78 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 78

Advancing to step 2:
When dividing 70 by 78, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Take the next digit (1) from the dividend and append it to 70, then repeat: 701 / 78

Step 3:
701 divided by 78 is 8 with a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 624 from 701 leaves us with 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 78

Step 4:
78 goes into 770 9 times with a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we take 702 away from 770, we end up with 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 78

Let's proceed to step 5:
When dividing 687 by 78, we get 8 with a remainder of 63.
Put 8 as the next digit of the answer. 
Result so far: 898.0
The remainder is 63 after subtracting 624 from 687.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 78

Moving on to step 6:
78 goes into 630 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8988.0
Subtracting 624 from 630 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 78

Going ahead to step 7:
78 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 89880.0
Subtract 0 from 63 to get 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 78

Step 8:
78 can be fit into 633 8 times, resulting in a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 898808.0
Subtract 624 from 633 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
If we divide 90 by 78, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 898808.1
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
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: 898808.11
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.

The quotient of the division is 898808.11, and the remainder is 0.042.
