We look at the division of 292682 by 78 
The aim is to understand the frequency of 78 in 292682.

Advancing to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 78

Let's proceed to step 2:
29 divided by 78 is 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 78

Moving on to step 3:
If we divide 292 by 78, we get 3 and a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 58 after subtracting 234 from 292.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 78

Step 4:
The number 78 fits into 586 7 times, leaving a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 546 from 586 and we're left with 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 78

On to step 5:
If we divide 408 by 78, we get 5 and a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
If we subtract 390 from 408, we get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 78

Step 6:
78 goes into 182 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 3752.0
The remainder is 26 after subtracting 156 from 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
78 can be fit into 260 3 times, resulting in a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 3752.3
Subtract 234 from 260 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
78 can be fit into 260 3 times, resulting in a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 3752.33
If we take 234 away from 260, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 3752.33, with a leftover of 0.026.
