Let's divide 815416 by 78
The aim is to understand the frequency of 78 in 815416.

Let's proceed to step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 78

Advancing to step 2:
If we divide 81 by 78, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 78 from 81 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 78

On to step 3:
The number 78 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 78

Advancing to step 4:
78 goes into 354 4 times with a remainder of 42.
The next digit of our result is 4. 
Result so far: 104.0
Deduct 312 from 354 and we're left with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 78

Moving on to step 5:
The number 78 fits into 421 5 times, leaving a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 1045.0
Subtract 390 from 421 to get 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 78

Moving on to step 6:
78 goes into 316 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 10454.0
If we subtract 312 from 316, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10454.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
When dividing 400 by 78, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10454.05
The remainder is 10 after subtracting 390 from 400.
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 9:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 10454.051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
78 goes into 220 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 10454.0512
Subtract 156 from 220 to get 64.
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 11:
When dividing 640 by 78, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 10454.05128
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.

Moving on to step 12:
160 divided by 78 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10454.051282
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
When dividing 40 by 78, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10454.051282
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.

On to step 14:
400 divided by 78 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10454.05128205
Deduct 390 from 400 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.

Our division results in 10454.05128205 with a remaining 1e-08.
