We divide 78608017 by 587
The aim is to understand the frequency of 587 in 78608017.

Going ahead to step 1:
The number 587 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 587

On to step 2:
587 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 587

Step 3:
587 can be fit into 786 1 times, resulting in a remainder of 199.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 587 from 786, we get 199.
Take the next digit (0) from the dividend and append it to 199, then repeat: 1990 / 587

Let's proceed to step 4:
If we divide 1990 by 587, we get 3 and a remainder of 229.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1761 from 1990 leaves us with 229.
Take the next digit (8) from the dividend and append it to 229, then repeat: 2298 / 587

Moving on to step 5:
587 goes into 2298 3 times with a remainder of 537.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
The remainder is 537 after subtracting 1761 from 2298.
Take the next digit (0) from the dividend and append it to 537, then repeat: 5370 / 587

Moving on to step 6:
587 goes into 5370 9 times with a remainder of 87.
Put 9 as the next digit of the answer. 
Result so far: 1339.0
The remainder is 87 after subtracting 5283 from 5370.
Append the next digit (1) from the dividend to 87 and continue with: 871 / 587

Moving on to step 7:
871 divided by 587 is 1 with a remainder of 284.
The number 1 becomes the next digit in our result. 
Result so far: 13391.0
The remainder is 284 after subtracting 587 from 871.
Bring next digit (7) of the dividend behind the 284 and repeat the process: 2847 / 587

Going ahead to step 8:
2847 divided by 587 is 4 with a remainder of 499.
Put 4 as the next digit of the answer. 
Result so far: 133914.0
The remainder is 499 after subtracting 2348 from 2847.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Step 9:
If we divide 4990 by 587, we get 8 and a remainder of 294.
Write down 8 as next digit of the result. 
Result so far: 133914.8
Subtracting 4696 from 4990 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
587 can be fit into 2940 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 133914.85
If we subtract 2935 from 2940, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
If we divide 50 by 587, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 133914.85
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
If we divide 500 by 587, we get 0 and a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 133914.85
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 133914.85 with a remaining 0.005.
