85654453 divided by 78 
The aim is to understand the frequency of 78 in 85654453.

On to step 1:
8 divided by 78 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 78

Advancing to step 2:
78 goes into 85 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 78 away from 85, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 78

Advancing to step 3:
78 goes into 76 0 times with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 76 after subtracting 0 from 76.
Append the next digit (5) from the dividend to 76 and continue with: 765 / 78

Let's proceed to step 4:
78 can be fit into 765 9 times, resulting in a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtract 702 from 765 to get 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 78

Moving on to step 5:
The number 78 fits into 634 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 1098.0
Deduct 624 from 634 and we're left with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 78

Step 6:
The number 78 fits into 104 1 times, leaving a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 10981.0
If we subtract 78 from 104, we get 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 78

Let's proceed to step 7:
The number 78 fits into 265 3 times, leaving a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 109813.0
Subtracting 234 from 265 leaves us with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 78

Advancing to step 8:
The number 78 fits into 313 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 1098134.0
The remainder is 1 after subtracting 312 from 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
78 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1098134.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
78 goes into 100 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1098134.01
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 1098134.012
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
78 goes into 640 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1098134.0128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
160 divided by 78 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 1098134.01282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
78 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1098134.01282
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1098134.0128205
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 16:
100 divided by 78 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1098134.01282051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 1098134.01282051, with a leftover of 2.2e-08.
