771726 ÷ 78 
The aim is to understand the frequency of 78 in 771726.

Let's proceed to step 1:
78 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 78

Let's proceed to step 2:
The number 78 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 78

Going ahead to step 3:
771 divided by 78 is 9 with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 702 from 771, we get 69.
Fetch the next digit (7) from the dividend, attach it to 69 and continue: 697 / 78

Moving on to step 4:
If we divide 697 by 78, we get 8 and a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtracting 624 from 697 leaves us with 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 78

Moving on to step 5:
If we divide 732 by 78, we get 9 and a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 989.0
If we subtract 702 from 732, we get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 78

Advancing to step 6:
78 goes into 306 3 times with a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 9893.0
If we take 234 away from 306, we end up 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 7:
The number 78 fits into 720 9 times, leaving a remainder of 18.
The next digit of our result is 9. 
Result so far: 9893.9
If we take 702 away from 720, we end up 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.

On to step 8:
180 divided by 78 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 9893.92
Deduct 156 from 180 and we're left 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.

Going ahead to step 9:
78 goes into 240 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 9893.923
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.

Advancing to step 10:
78 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 9893.923
If we take 0 away from 60, we end up 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.

Let's proceed to step 11:
When dividing 600 by 78, we get 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 9893.92307
If we take 546 away from 600, we end up 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.

Let's proceed to step 12:
When dividing 540 by 78, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 9893.923076
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.

Step 13:
When dividing 720 by 78, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 9893.9230769
If we subtract 702 from 720, we 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.

On to step 14:
If we divide 180 by 78, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 9893.92307692
Deduct 156 from 180 and we're left 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.

The final outcome is 9893.92307692, with a leftover of 2.4e-08.
