Let's divide 936575 by 87
The aim is to understand the frequency of 87 in 936575.

Going ahead to step 1:
87 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 87

Let's proceed to step 2:
The number 87 fits into 93 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 6 after subtracting 87 from 93.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 87

Advancing to step 3:
66 divided by 87 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 87

On to step 4:
665 divided by 87 is 7 with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 107.0
The remainder is 56 after subtracting 609 from 665.
Grab the next digit (7) from the dividend, add it to 56, then carry on: 567 / 87

Step 5:
87 goes into 567 6 times with a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 1076.0
If we subtract 522 from 567, we get 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 87

On to step 6:
If we divide 455 by 87, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 10765.0
Subtracting 435 from 455 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
When dividing 200 by 87, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 10765.2
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.

Going ahead to step 8:
When dividing 260 by 87, we get 2 with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 10765.22
If we subtract 174 from 260, we 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 10765.22, with a leftover of 0.086.
