We look at the division of 676493 by 87 
The aim is to understand the frequency of 87 in 676493.

Going ahead to step 1:
When dividing 6 by 87, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 87

Advancing to step 2:
When dividing 67 by 87, we get 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Fetch the next digit (6) from the dividend, attach it to 67 and continue: 676 / 87

On to step 3:
676 divided by 87 is 7 with a remainder of 67.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 67 after subtracting 609 from 676.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 87

Let's proceed to step 4:
When dividing 674 by 87, we get 7 with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
The remainder is 65 after subtracting 609 from 674.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 87

Step 5:
When dividing 659 by 87, we get 7 with a remainder of 50.
The next digit of our result is 7. 
Result so far: 777.0
Subtracting 609 from 659 leaves us with 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 87

Let's proceed to step 6:
87 goes into 503 5 times with a remainder of 68.
The number 5 becomes the next digit in our result. 
Result so far: 7775.0
Subtract 435 from 503 to get 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 7:
The number 87 fits into 680 7 times, leaving a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 7775.7
Subtract 609 from 680 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 8:
87 can be fit into 710 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 7775.78
If we take 696 away from 710, we end up 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.

Step 9:
140 divided by 87 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 7775.781
If we take 87 away from 140, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 10:
The number 87 fits into 530 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 7775.7816
If we take 522 away from 530, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
When dividing 80 by 87, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 7775.7816
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
87 goes into 800 9 times with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 7775.781609
Subtracting 783 from 800 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 13:
The number 87 fits into 170 1 times, leaving a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 7775.7816091
Subtract 87 from 170 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 14:
87 goes into 830 9 times with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 7775.78160919
Deduct 783 from 830 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 7775.78160919 with a remaining 4.7e-08.
