We look at the division of 89440137 by 78 
The aim is to understand the frequency of 78 in 89440137.

On to step 1:
If we divide 8 by 78, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 78

Moving on to step 2:
If we divide 89 by 78, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 78 away from 89, we end up with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 78

Going ahead to step 3:
114 divided by 78 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 78 from 114 to get 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 78

Going ahead to step 4:
If we divide 364 by 78, we get 4 and a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtracting 312 from 364 leaves us with 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 78

Let's proceed to step 5:
When dividing 520 by 78, we get 6 with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 1146.0
The remainder is 52 after subtracting 468 from 520.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 78

Advancing to step 6:
78 goes into 521 6 times with a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 11466.0
If we subtract 468 from 521, we get 53.
Take the next digit (3) from the dividend and append it to 53, then repeat: 533 / 78

Step 7:
When dividing 533 by 78, we get 6 with a remainder of 65.
The number 6 becomes the next digit in our result. 
Result so far: 114666.0
Deduct 468 from 533 and we're left with 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 78

Moving on to step 8:
The number 78 fits into 657 8 times, leaving a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 1146668.0
If we subtract 624 from 657, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
When dividing 330 by 78, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 1146668.4
Subtracting 312 from 330 leaves us with 18.
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 10:
180 divided by 78 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 1146668.42
Subtracting 156 from 180 leaves us 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.

On to step 11:
240 divided by 78 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 1146668.423
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
When dividing 60 by 78, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1146668.423
Subtract 0 from 60 to 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 13:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 1146668.42307
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 1146668.423076
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.

Advancing to step 15:
If we divide 720 by 78, we get 9 and a remainder of 18.
The next digit of our result is 9. 
Result so far: 1146668.4230769
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.

Advancing to step 16:
180 divided by 78 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1146668.42307692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 1146668.42307692 with a remainder of 2.4e-08.
