We look at the division of 92942 by 78 
The aim is to understand the frequency of 78 in 92942.

On to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 78

Moving on to step 2:
The number 78 fits into 92 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 78 from 92 leaves us with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 78

Moving on to step 3:
If we divide 149 by 78, we get 1 and a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 78 away from 149, we end up with 71.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 78

Advancing to step 4:
The number 78 fits into 714 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Deduct 702 from 714 and we're left with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 78

Going ahead to step 5:
When dividing 122 by 78, we get 1 with a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 1191.0
Subtract 78 from 122 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 6:
78 goes into 440 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1191.5
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
78 can be fit into 500 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1191.56
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
The number 78 fits into 320 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 1191.564
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1191.5641
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
20 divided by 78 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1191.5641
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
200 divided by 78 is 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 1191.564102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1191.5641025
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1191.56410256
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 1191.56410256 and a remainder of 3.2e-08.
