774483 divided by 78 
The aim is to understand the frequency of 78 in 774483.

Moving on to step 1:
78 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 78

Advancing to step 2:
If we divide 77 by 78, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 78

Moving on to step 3:
When dividing 774 by 78, we get 9 with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 702 from 774 leaves us with 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 78

On to step 4:
When dividing 724 by 78, we get 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 99.0
If we take 702 away from 724, we end up with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 78

Let's proceed to step 5:
If we divide 228 by 78, we get 2 and a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 992.0
Subtract 156 from 228 to get 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 78

Advancing to step 6:
When dividing 723 by 78, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 9929.0
If we subtract 702 from 723, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
The number 78 fits into 210 2 times, leaving a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 9929.2
If we subtract 156 from 210, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 9929.26
Subtract 468 from 540 to 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 9:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 9929.269
Subtract 702 from 720 to 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 10:
78 goes into 180 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 9929.2692
The remainder is 24 after subtracting 156 from 180.
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 11:
When dividing 240 by 78, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 9929.26923
If we subtract 234 from 240, we 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.

Step 12:
If we divide 60 by 78, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 9929.26923
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
78 can be fit into 600 7 times, resulting in a remainder of 54.
The next digit of our result is 7. 
Result so far: 9929.2692307
Subtracting 546 from 600 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.

Step 14:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 9929.26923076
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.

After the division, we end up with 9929.26923076 and a remainder of 7.2e-08.
