We're dividing 488660 by 78 
The aim is to understand the frequency of 78 in 488660.

Let's proceed to step 1:
The number 78 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 78

On to step 2:
78 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 78

Going ahead to step 3:
78 can be fit into 488 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 468 from 488 and we're left with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 78

Step 4:
206 divided by 78 is 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we subtract 156 from 206, we get 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 78

On to step 5:
If we divide 506 by 78, we get 6 and a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 626.0
If we subtract 468 from 506, we get 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 78

Let's proceed to step 6:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 6264.0
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 6264.8
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
78 can be fit into 560 7 times, resulting in a remainder of 14.
The next digit of our result is 7. 
Result so far: 6264.87
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 6264.871
Subtracting 78 from 140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
When dividing 620 by 78, we get 7 with a remainder of 74.
The next digit of our result is 7. 
Result so far: 6264.8717
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
If we divide 740 by 78, we get 9 and a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 6264.87179
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
If we divide 380 by 78, we get 4 and a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 6264.871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
680 divided by 78 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 6264.8717948
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
If we divide 560 by 78, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 6264.87179487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 6264.87179487 with a remainder of 1.4e-08.
