We're dividing 274394 by 87 
The aim is to understand the frequency of 87 in 274394.

Advancing to step 1:
87 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 87

Going ahead to step 2:
87 can be fit into 27 0 times, resulting in a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 87

Moving on to step 3:
The number 87 fits into 274 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 261 away from 274, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 87

Step 4:
If we divide 133 by 87, we get 1 and a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 87 from 133, we get 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 87

Going ahead to step 5:
469 divided by 87 is 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 315.0
If we take 435 away from 469, we end up with 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 87

On to step 6:
When dividing 344 by 87, we get 3 with a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 3153.0
The remainder is 83 after subtracting 261 from 344.
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 7:
If we divide 830 by 87, we get 9 and a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 3153.9
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.

Moving on to step 8:
470 divided by 87 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3153.95
Subtracting 435 from 470 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
The number 87 fits into 350 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 3153.954
Deduct 348 from 350 and we're left 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.

Let's proceed to step 10:
87 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 3153.954
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
87 goes into 200 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 3153.95402
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
87 goes into 260 2 times with a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 3153.954022
Subtract 174 from 260 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 3153.954022, with a leftover of 8.6e-06.
