We're dividing 55699 by 78 
The aim is to understand the frequency of 78 in 55699.

Going ahead to step 1:
78 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 78

On to step 2:
The number 78 fits into 55 0 times, leaving a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 78

Let's proceed to step 3:
If we divide 556 by 78, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 546 away from 556, we end up with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 78

On to step 4:
109 divided by 78 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we take 78 away from 109, we end up with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 78

Let's proceed to step 5:
78 can be fit into 319 4 times, resulting in a remainder of 7.
The next digit of our result is 4. 
Result so far: 714.0
The remainder is 7 after subtracting 312 from 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 6:
The number 78 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 714.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 7:
The number 78 fits into 700 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 714.08
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 8:
760 divided by 78 is 9 with a remainder of 58.
The next digit of our result is 9. 
Result so far: 714.089
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 714.0897
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
78 can be fit into 340 4 times, resulting in a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 714.08974
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
When dividing 280 by 78, we get 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 714.089743
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
460 divided by 78 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 714.0897435
If we subtract 390 from 460, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
When dividing 700 by 78, we get 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 714.08974358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 714.08974358, with a leftover of 7.6e-08.
