We're dividing 34674 by 87 
The aim is to understand the frequency of 87 in 34674.

Moving on to step 1:
If we divide 3 by 87, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 87

Going ahead to step 2:
The number 87 fits into 34 0 times, leaving a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Append the next digit (6) from the dividend to 34 and continue with: 346 / 87

Moving on to step 3:
When dividing 346 by 87, we get 3 with a remainder of 85.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 261 from 346 leaves us with 85.
Fetch the next digit (7) from the dividend, attach it to 85 and continue: 857 / 87

Moving on to step 4:
If we divide 857 by 87, we get 9 and a remainder of 74.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 783 from 857 to get 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 87

Moving on to step 5:
The number 87 fits into 744 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 398.0
Subtract 696 from 744 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 6:
If we divide 480 by 87, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 398.5
Subtract 435 from 480 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
87 goes into 450 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 398.55
Deduct 435 from 450 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 398.55 with a remainder of 0.015.
