587508 ÷ 78 
The aim is to understand the frequency of 78 in 587508.

Going ahead to step 1:
78 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 78

Step 2:
58 divided by 78 is 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Include the next digit (7) from the dividend after 58, then repeat: 587 / 78

Advancing to step 3:
When dividing 587 by 78, we get 7 with a remainder of 41.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 546 from 587, we get 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 78

Moving on to step 4:
415 divided by 78 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 25 after subtracting 390 from 415.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 78

Advancing to step 5:
78 goes into 250 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 753.0
Subtracting 234 from 250 leaves us with 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 78

Step 6:
When dividing 168 by 78, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 7532.0
If we take 156 away from 168, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 78 fits into 120 1 times, leaving a remainder of 42.
The next digit of our result is 1. 
Result so far: 7532.1
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 8:
When dividing 420 by 78, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7532.15
Deduct 390 from 420 and we're left 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 9:
300 divided by 78 is 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 7532.153
Subtracting 234 from 300 leaves us 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.

Let's proceed to step 10:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 7532.1538
Subtract 624 from 660 to 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.

On to step 11:
When dividing 360 by 78, we get 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 7532.15384
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 12:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 7532.153846
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.

Step 13:
If we divide 120 by 78, we get 1 and a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 7532.1538461
If we take 78 away from 120, we end up 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 14:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 7532.15384615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 7532.15384615 with a remaining 3e-08.
