We're dividing 299908 by 87 
The aim is to understand the frequency of 87 in 299908.

Advancing to step 1:
If we divide 2 by 87, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 87

Advancing to step 2:
If we divide 29 by 87, we get 0 and a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 87

Going ahead to step 3:
87 goes into 299 3 times with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 261 from 299, we get 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 87

On to step 4:
The number 87 fits into 389 4 times, leaving a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 348 from 389 to get 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 87

On to step 5:
When dividing 410 by 87, we get 4 with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 344.0
Deduct 348 from 410 and we're left with 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 87

Step 6:
87 can be fit into 628 7 times, resulting in a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 3447.0
The remainder is 19 after subtracting 609 from 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 87 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3447.2
Deduct 174 from 190 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
160 divided by 87 is 1 with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 3447.21
Subtracting 87 from 160 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
The number 87 fits into 730 8 times, leaving a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 3447.218
Subtract 696 from 730 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
340 divided by 87 is 3 with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 3447.2183
The remainder is 79 after subtracting 261 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 11:
87 can be fit into 790 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 3447.21839
Deduct 783 from 790 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
87 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 3447.21839
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
The number 87 fits into 700 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 3447.2183908
If we take 696 away from 700, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
87 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3447.2183908
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 3447.2183908 and a remainder of 4e-08.
