We divide 971154 by 78
The aim is to understand the frequency of 78 in 971154.

Advancing to step 1:
9 divided by 78 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 78

On to step 2:
78 can be fit into 97 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 78 from 97, we get 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 78

Step 3:
78 goes into 191 2 times with a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 156 from 191 leaves us with 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 78

Moving on to step 4:
When dividing 351 by 78, we get 4 with a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 124.0
The remainder is 39 after subtracting 312 from 351.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 78

Advancing to step 5:
78 goes into 395 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1245.0
Subtracting 390 from 395 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 78

Step 6:
If we divide 54 by 78, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 12450.0
Subtracting 0 from 54 leaves us 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.

On to step 7:
78 goes into 540 6 times with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 12450.6
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 8:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 12450.69
Deduct 702 from 720 and we're left 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.

Going ahead to step 9:
180 divided by 78 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 12450.692
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.

Let's proceed to step 10:
240 divided by 78 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 12450.6923
If we take 234 away from 240, we end up 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.

Going ahead to step 11:
60 divided by 78 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 12450.6923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
When dividing 600 by 78, we get 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 12450.692307
The remainder is 54 after subtracting 546 from 600.
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:
When dividing 540 by 78, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 12450.6923076
If we subtract 468 from 540, we get 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:
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: 12450.69230769
Deduct 702 from 720 and we're left 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.

The final outcome is 12450.69230769, with a leftover of 1.8e-08.
