We're dividing 56665461 by 78 
The aim is to understand the frequency of 78 in 56665461.

Moving on to step 1:
5 divided by 78 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 78

Advancing to step 2:
78 can be fit into 56 0 times, resulting in a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 78

Step 3:
The number 78 fits into 566 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 546 from 566 and we're left with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 78

Advancing to step 4:
When dividing 206 by 78, we get 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 50 after subtracting 156 from 206.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 78

Advancing to step 5:
505 divided by 78 is 6 with a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 726.0
The remainder is 37 after subtracting 468 from 505.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 78

On to step 6:
The number 78 fits into 374 4 times, leaving a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 7264.0
If we subtract 312 from 374, we get 62.
Append the next digit (6) from the dividend to 62 and continue with: 626 / 78

Advancing to step 7:
626 divided by 78 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 72648.0
Subtracting 624 from 626 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 78

Going ahead to step 8:
21 divided by 78 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 726480.0
Deduct 0 from 21 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
78 goes into 210 2 times with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 726480.2
Deduct 156 from 210 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.

On to step 10:
If we divide 540 by 78, we get 6 and a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 726480.26
If we take 468 away from 540, 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.

On to step 11:
78 can be fit into 720 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 726480.269
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.

On to step 12:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 726480.2692
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.

Let's proceed to step 13:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 726480.26923
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 726480.26923
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.

Going ahead to step 15:
78 goes into 600 7 times with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 726480.2692307
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 16:
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: 726480.26923076
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.

The final outcome is 726480.26923076, with a leftover of 7.2e-08.
