We divide 580815 by 78
The aim is to understand the frequency of 78 in 580815.

Let's proceed to step 1:
78 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 78

On to step 2:
If we divide 58 by 78, we get 0 and a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 78

Moving on to step 3:
If we divide 580 by 78, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 7.0
If we take 546 away from 580, we end up with 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 78

On to step 4:
78 goes into 348 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtract 312 from 348 to get 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 78

Step 5:
78 goes into 361 4 times with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 744.0
Subtract 312 from 361 to get 49.
Append the next digit (5) from the dividend to 49 and continue with: 495 / 78

Moving on to step 6:
When dividing 495 by 78, we get 6 with a remainder of 27.
The next digit of our result is 6. 
Result so far: 7446.0
If we subtract 468 from 495, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
If we divide 270 by 78, we get 3 and a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 7446.3
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 7446.34
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 78, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 7446.346
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
120 divided by 78 is 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 7446.3461
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
When dividing 420 by 78, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 7446.34615
Subtracting 390 from 420 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.

Moving on to step 12:
78 can be fit into 300 3 times, resulting in a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 7446.346153
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
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: 7446.3461538
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 7446.34615384
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 7446.34615384 with a balance of 4.8e-08.
