We divide 124429 by 78
The aim is to understand the frequency of 78 in 124429.

On to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 78

Moving on to step 2:
12 divided by 78 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 78

Advancing to step 3:
When dividing 124 by 78, we get 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 78 from 124 and we're left with 46.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 78

Going ahead to step 4:
78 goes into 464 5 times with a remainder of 74.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 390 from 464 to get 74.
Include the next digit (2) from the dividend after 74, then repeat: 742 / 78

Going ahead to step 5:
When dividing 742 by 78, we get 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we subtract 702 from 742, we get 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 78

Moving on to step 6:
The number 78 fits into 409 5 times, leaving a remainder of 19.
The next digit of our result is 5. 
Result so far: 1595.0
If we subtract 390 from 409, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 78 is 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 1595.2
If we subtract 156 from 190, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
The number 78 fits into 340 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 1595.24
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 78, we get 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 1595.243
If we subtract 234 from 280, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 1595.2435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
700 divided by 78 is 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 1595.24358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 1595.243589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
580 divided by 78 is 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 1595.2435897
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
78 goes into 340 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 1595.24358974
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 1595.24358974 with a remaining 2.8e-08.
