We look at the division of 958752 by 78 
The aim is to understand the frequency of 78 in 958752.

Advancing to step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 78

Advancing to step 2:
If we divide 95 by 78, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 78 from 95 to get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 78

Advancing to step 3:
78 goes into 178 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 156 from 178 to get 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 78

Let's proceed to step 4:
78 goes into 227 2 times with a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Deduct 156 from 227 and we're left with 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 78

Advancing to step 5:
78 goes into 715 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 1229.0
The remainder is 13 after subtracting 702 from 715.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 78

Going ahead to step 6:
The number 78 fits into 132 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 12291.0
The remainder is 54 after subtracting 78 from 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
78 goes into 540 6 times with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 12291.6
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 8:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 12291.69
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
78 goes into 180 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12291.692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
240 divided by 78 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 12291.6923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 12291.6923
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
600 divided by 78 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 12291.692307
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
If we divide 540 by 78, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 12291.6923076
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
When dividing 720 by 78, we get 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 12291.69230769
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 12291.69230769 and a remainder of 1.8e-08.
