170529 ÷ 87 
The aim is to understand the frequency of 87 in 170529.

On to step 1:
87 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 87

Going ahead to step 2:
87 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 87

Let's proceed to step 3:
If we divide 170 by 87, we get 1 and a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 87 from 170 to get 83.
Include the next digit (5) from the dividend after 83, then repeat: 835 / 87

Moving on to step 4:
87 goes into 835 9 times with a remainder of 52.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 52 after subtracting 783 from 835.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 87

Going ahead to step 5:
When dividing 522 by 87, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
Subtracting 522 from 522 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 87

Let's proceed to step 6:
The number 87 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 1960.0
Subtracting 0 from 9 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
87 can be fit into 90 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1960.1
If we take 87 away from 90, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
If we divide 30 by 87, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1960.1
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 87 is 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 1960.103
If we subtract 261 from 300, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
390 divided by 87 is 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 1960.1034
If we subtract 348 from 390, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
When dividing 420 by 87, we get 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 1960.10344
Deduct 348 from 420 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 1960.10344 with a remainder of 7.2e-05.
