734717 divided by 87 
The aim is to understand the frequency of 87 in 734717.

Moving on to step 1:
7 divided by 87 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 87

Moving on to step 2:
The number 87 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Include the next digit (4) from the dividend after 73, then repeat: 734 / 87

Step 3:
The number 87 fits into 734 8 times, leaving a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 696 from 734 to get 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 87

On to step 4:
The number 87 fits into 387 4 times, leaving a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Deduct 348 from 387 and we're left with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 87

Step 5:
391 divided by 87 is 4 with a remainder of 43.
The next digit of our result is 4. 
Result so far: 844.0
If we take 348 away from 391, we end up with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 87

Going ahead to step 6:
87 can be fit into 437 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 8445.0
Subtracting 435 from 437 leaves us 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.

Step 7:
87 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8445.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
87 can be fit into 200 2 times, resulting in a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 8445.02
The remainder is 26 after subtracting 174 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
If we divide 260 by 87, we get 2 and a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 8445.022
If we take 174 away from 260, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 8445.022 and a remainder of 0.0086.
