We're dividing 722951 by 78 
The aim is to understand the frequency of 78 in 722951.

Advancing to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 78

Let's proceed to step 2:
When dividing 72 by 78, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 78

Advancing to step 3:
The number 78 fits into 722 9 times, leaving a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 702 from 722 and we're left with 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 78

Let's proceed to step 4:
209 divided by 78 is 2 with a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 92.0
If we take 156 away from 209, we end up with 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 78

Advancing to step 5:
78 can be fit into 535 6 times, resulting in a remainder of 67.
Write down 6 as next digit of the result. 
Result so far: 926.0
Deduct 468 from 535 and we're left with 67.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 78

Step 6:
78 can be fit into 671 8 times, resulting in a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 9268.0
Subtract 624 from 671 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
When dividing 470 by 78, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 9268.6
If we take 468 away from 470, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9268.6
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 78, we get 2 and a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 9268.602
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
If we divide 440 by 78, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 9268.6025
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
78 can be fit into 500 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 9268.60256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
When dividing 320 by 78, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 9268.602564
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
When dividing 80 by 78, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 9268.6025641
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9268.6025641
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 9268.6025641 with a remainder of 2e-08.
