We look at the division of 953729 by 87 
The aim is to understand the frequency of 87 in 953729.

Moving on to step 1:
When dividing 9 by 87, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 87

Step 2:
95 divided by 87 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 87 away from 95, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 87

Let's proceed to step 3:
87 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 83 and we're left with 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 87

Advancing to step 4:
If we divide 837 by 87, we get 9 and a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Deduct 783 from 837 and we're left with 54.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 87

Let's proceed to step 5:
If we divide 542 by 87, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 1096.0
If we take 522 away from 542, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 87

Step 6:
87 can be fit into 209 2 times, resulting in a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 10962.0
Deduct 174 from 209 and we're left 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.

Moving on to step 7:
350 divided by 87 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 10962.4
If we subtract 348 from 350, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
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: 10962.4
Subtracting 0 from 20 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.

Moving on to step 9:
When dividing 200 by 87, we get 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 10962.402
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.

On to step 10:
87 goes into 260 2 times with a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 10962.4022
Subtracting 174 from 260 leaves us 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.

Our division results in 10962.4022 with a remaining 0.00086.
