We divide 427911 by 78
The aim is to understand the frequency of 78 in 427911.

Step 1:
The number 78 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 78

Let's proceed to step 2:
78 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 78

On to step 3:
When dividing 427 by 78, we get 5 with a remainder of 37.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 37 after subtracting 390 from 427.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 78

Going ahead to step 4:
The number 78 fits into 379 4 times, leaving a remainder of 67.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we take 312 away from 379, we end up with 67.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 78

Moving on to step 5:
If we divide 671 by 78, we get 8 and a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 548.0
The remainder is 47 after subtracting 624 from 671.
Bring next digit (1) of the dividend behind the 47 and repeat the process: 471 / 78

Let's proceed to step 6:
When dividing 471 by 78, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 5486.0
If we take 468 away from 471, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 78 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5486.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 78, we get 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 5486.03
If we subtract 234 from 300, we get 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 9:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 5486.038
If we subtract 624 from 660, we 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.

Step 10:
When dividing 360 by 78, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 5486.0384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
78 goes into 480 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 5486.03846
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.

Going ahead to step 12:
120 divided by 78 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 5486.038461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
420 divided by 78 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5486.0384615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
When dividing 300 by 78, we get 3 with a remainder of 66.
The next digit of our result is 3. 
Result so far: 5486.03846153
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 5486.03846153 with a remainder of 6.6e-08.
