Let's divide 152136 by 78
The aim is to understand the frequency of 78 in 152136.

Step 1:
78 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 78

Moving on to step 2:
78 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 78

On to step 3:
The number 78 fits into 152 1 times, leaving a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 78 from 152 to get 74.
Fetch the next digit (1) from the dividend, attach it to 74 and continue: 741 / 78

Let's proceed to step 4:
78 goes into 741 9 times with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 39 after subtracting 702 from 741.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 78

Advancing to step 5:
The number 78 fits into 393 5 times, leaving a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
Subtracting 390 from 393 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 78

On to step 6:
78 can be fit into 36 0 times, resulting in a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 1950.0
Subtract 0 from 36 to 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.

Moving on to step 7:
360 divided by 78 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 1950.4
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
78 can be fit into 480 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 1950.46
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
When dividing 120 by 78, we get 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1950.461
If we subtract 78 from 120, we 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.

Moving on to step 10:
78 goes into 420 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1950.4615
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.

Let's proceed to step 11:
When dividing 300 by 78, we get 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 1950.46153
If we take 234 away from 300, 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.

On to step 12:
78 can be fit into 660 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 1950.461538
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
When dividing 360 by 78, we get 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 1950.4615384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
If we divide 480 by 78, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 1950.46153846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 1950.46153846, with a leftover of 1.2e-08.
