Let's divide 430851 by 78
The aim is to understand the frequency of 78 in 430851.

Step 1:
If we divide 4 by 78, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 78

Advancing to step 2:
The number 78 fits into 43 0 times, leaving a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 78

Advancing to step 3:
The number 78 fits into 430 5 times, leaving a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 390 away from 430, we end up with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 78

Moving on to step 4:
If we divide 408 by 78, we get 5 and a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 55.0
The remainder is 18 after subtracting 390 from 408.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 78

Moving on to step 5:
If we divide 185 by 78, we get 2 and a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 552.0
Subtract 156 from 185 to get 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 78

Going ahead to step 6:
When dividing 291 by 78, we get 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 5523.0
If we take 234 away from 291, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
570 divided by 78 is 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 5523.7
Subtracting 546 from 570 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 5523.73
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
78 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5523.73
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
When dividing 600 by 78, we get 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 5523.7307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
If we divide 540 by 78, we get 6 and a remainder of 72.
The next digit of our result is 6. 
Result so far: 5523.73076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
When dividing 720 by 78, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 5523.730769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
78 goes into 180 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 5523.7307692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 5523.73076923
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 5523.73076923 with a remaining 6e-09.
