303106 ÷ 87 
The aim is to understand the frequency of 87 in 303106.

Step 1:
3 divided by 87 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 87

Advancing to step 2:
30 divided by 87 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 87

Let's proceed to step 3:
When dividing 303 by 87, we get 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 261 from 303 and we're left with 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 87

Step 4:
87 can be fit into 421 4 times, resulting in a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 34.0
Deduct 348 from 421 and we're left with 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 87

Moving on to step 5:
87 goes into 730 8 times with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 348.0
If we take 696 away from 730, we end up with 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 87

Going ahead to step 6:
When dividing 346 by 87, we get 3 with a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 3483.0
If we take 261 away from 346, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 7:
If we divide 850 by 87, we get 9 and a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 3483.9
Subtract 783 from 850 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 8:
If we divide 670 by 87, we get 7 and a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 3483.97
Subtracting 609 from 670 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
When dividing 610 by 87, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 3483.977
The remainder is 1 after subtracting 609 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 3483.977 with a remainder of 0.0001.
