We look at the division of 674999 by 87 
The aim is to understand the frequency of 87 in 674999.

Going ahead to step 1:
When dividing 6 by 87, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 87

Going ahead to step 2:
87 can be fit into 67 0 times, resulting in a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 87

On to step 3:
The number 87 fits into 674 7 times, leaving a remainder of 65.
The next digit of our result is 7. 
Result so far: 7.0
If we take 609 away from 674, we end up with 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 87

On to step 4:
87 goes into 659 7 times with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Deduct 609 from 659 and we're left with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 87

Step 5:
87 can be fit into 509 5 times, resulting in a remainder of 74.
Write down 5 as next digit of the result. 
Result so far: 775.0
If we take 435 away from 509, we end up with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 87

On to step 6:
When dividing 749 by 87, we get 8 with a remainder of 53.
The next digit of our result is 8. 
Result so far: 7758.0
If we take 696 away from 749, 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.

Moving on to step 7:
530 divided by 87 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 7758.6
If we subtract 522 from 530, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
87 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 7758.6
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
The number 87 fits into 800 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 7758.609
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.

Let's proceed to step 10:
If we divide 170 by 87, we get 1 and a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 7758.6091
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.

Going ahead to step 11:
When dividing 830 by 87, we get 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 7758.60919
The remainder is 47 after subtracting 783 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 12:
The number 87 fits into 470 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 7758.609195
Subtract 435 from 470 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
87 can be fit into 350 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 7758.6091954
If we take 348 away from 350, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 87 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7758.6091954
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 7758.6091954 with a remainder of 2e-08.
