56369 ÷ 78 
The aim is to understand the frequency of 78 in 56369.

Let's proceed to step 1:
5 divided by 78 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 78

Let's proceed to step 2:
If we divide 56 by 78, we get 0 and a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Bring next digit (3) of the dividend behind the 56 and repeat the process: 563 / 78

Advancing to step 3:
563 divided by 78 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 17 after subtracting 546 from 563.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 78

On to step 4:
78 goes into 176 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtract 156 from 176 to get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 78

Let's proceed to step 5:
78 can be fit into 209 2 times, resulting in a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 722.0
Subtract 156 from 209 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 6:
If we divide 530 by 78, we get 6 and a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 722.6
Subtracting 468 from 530 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 7:
78 goes into 620 7 times with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 722.67
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 8:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 722.679
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
If we divide 380 by 78, we get 4 and a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 722.6794
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
The number 78 fits into 680 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 722.67948
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 722.679487
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
78 can be fit into 140 1 times, resulting in a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 722.6794871
Subtract 78 from 140 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
78 goes into 620 7 times with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 722.67948717
The remainder is 74 after subtracting 546 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final outcome is 722.67948717, with a leftover of 7.4e-08.
