We divide 654724 by 78
The aim is to understand the frequency of 78 in 654724.

Advancing to step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 78

On to step 2:
If we divide 65 by 78, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 78

Going ahead to step 3:
The number 78 fits into 654 8 times, leaving a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 30 after subtracting 624 from 654.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 78

Advancing to step 4:
307 divided by 78 is 3 with a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we subtract 234 from 307, we get 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 78

Advancing to step 5:
732 divided by 78 is 9 with a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 839.0
If we subtract 702 from 732, we get 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 78

Going ahead to step 6:
If we divide 304 by 78, we get 3 and a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 8393.0
Subtract 234 from 304 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 7:
700 divided by 78 is 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 8393.8
If we take 624 away from 700, we end up 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.

Moving on to step 8:
When dividing 760 by 78, we get 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 8393.89
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.

Let's proceed to step 9:
580 divided by 78 is 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 8393.897
Subtracting 546 from 580 leaves us 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.

Going ahead to step 10:
78 goes into 340 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 8393.8974
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.

Step 11:
78 goes into 280 3 times with a remainder of 46.
The next digit of our result is 3. 
Result so far: 8393.89743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
78 goes into 460 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 8393.897435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 13:
If we divide 700 by 78, we get 8 and a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 8393.8974358
If we take 624 away from 700, we end up 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.

On to step 14:
78 goes into 760 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 8393.89743589
If we subtract 702 from 760, we 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.

After the division, we end up with 8393.89743589 and a remainder of 5.8e-08.
