Let's divide 748164 by 78
The aim is to understand the frequency of 78 in 748164.

Step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 78

Going ahead to step 2:
When dividing 74 by 78, we get 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 78

Let's proceed to step 3:
The number 78 fits into 748 9 times, leaving a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 702 from 748 leaves us with 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 78

Let's proceed to step 4:
78 can be fit into 461 5 times, resulting in a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we subtract 390 from 461, we get 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 78

On to step 5:
78 goes into 716 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 959.0
If we subtract 702 from 716, we get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 78

Advancing to step 6:
When dividing 144 by 78, we get 1 with a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 9591.0
If we take 78 away from 144, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
If we divide 660 by 78, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 9591.8
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
78 goes into 360 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 9591.84
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 9591.846
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
If we divide 120 by 78, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 9591.8461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
If we divide 420 by 78, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 9591.84615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
78 goes into 300 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 9591.846153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
When dividing 660 by 78, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 9591.8461538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
78 can be fit into 360 4 times, resulting in a remainder of 48.
The next digit of our result is 4. 
Result so far: 9591.84615384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 9591.84615384, with a leftover of 4.8e-08.
