We look at the division of 730002 by 87 
The aim is to understand the frequency of 87 in 730002.

Going ahead to step 1:
If we divide 7 by 87, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 87

On to step 2:
The number 87 fits into 73 0 times, leaving a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 87

On to step 3:
87 can be fit into 730 8 times, resulting in a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 696 away from 730, we end up with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 87

Going ahead to step 4:
340 divided by 87 is 3 with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we subtract 261 from 340, we get 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 87

Going ahead to step 5:
87 goes into 790 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 839.0
Deduct 783 from 790 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 87

Step 6:
72 divided by 87 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 8390.0
Subtract 0 from 72 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 7:
If we divide 720 by 87, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8390.8
Subtract 696 from 720 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
240 divided by 87 is 2 with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 8390.82
Deduct 174 from 240 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
87 can be fit into 660 7 times, resulting in a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 8390.827
Deduct 609 from 660 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
The number 87 fits into 510 5 times, leaving a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 8390.8275
The remainder is 75 after subtracting 435 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
87 goes into 750 8 times with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 8390.82758
If we take 696 away from 750, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
When dividing 540 by 87, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 8390.827586
If we take 522 away from 540, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
87 goes into 180 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 8390.8275862
If we subtract 174 from 180, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
87 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8390.8275862
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 8390.8275862 and a remainder of 6e-08.
