We're dividing 149215 by 78 
The aim is to understand the frequency of 78 in 149215.

Advancing to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 78

Advancing to step 2:
The number 78 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 78

Let's proceed to step 3:
If we divide 149 by 78, we get 1 and a remainder of 71.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 78 from 149 leaves us with 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 78

Step 4:
When dividing 712 by 78, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 10 after subtracting 702 from 712.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 78

Step 5:
78 goes into 101 1 times with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
If we take 78 away from 101, we end up with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 78

Going ahead to step 6:
The number 78 fits into 235 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1913.0
Subtracting 234 from 235 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 78 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1913.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 78 fits into 100 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 1913.01
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
When dividing 220 by 78, we get 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 1913.012
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
If we divide 640 by 78, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1913.0128
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
78 goes into 160 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1913.01282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 78, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1913.01282
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1913.0128205
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
If we divide 100 by 78, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 1913.01282051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 1913.01282051 and a remainder of 2.2e-08.
