959357 divided by 78 
The aim is to understand the frequency of 78 in 959357.

On to step 1:
9 divided by 78 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 78

Going ahead to step 2:
78 goes into 95 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 78 away from 95, we end up with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 78

Going ahead to step 3:
If we divide 179 by 78, we get 2 and a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 23 after subtracting 156 from 179.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 78

Advancing to step 4:
78 goes into 233 2 times with a remainder of 77.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtract 156 from 233 to get 77.
Bring next digit (5) of the dividend behind the 77 and repeat the process: 775 / 78

Let's proceed to step 5:
78 goes into 775 9 times with a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 1229.0
If we subtract 702 from 775, we get 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 78

Advancing to step 6:
78 can be fit into 737 9 times, resulting in a remainder of 35.
The next digit of our result is 9. 
Result so far: 12299.0
Subtracting 702 from 737 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
350 divided by 78 is 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 12299.4
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
78 can be fit into 380 4 times, resulting in a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 12299.44
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 12299.44, with a leftover of 0.068.
