We're dividing 87904239 by 101 
The aim is to understand the frequency of 101 in 87904239.

Step 1:
101 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 101

Going ahead to step 2:
101 goes into 87 0 times with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Append the next digit (9) from the dividend to 87 and continue with: 879 / 101

Step 3:
If we divide 879 by 101, we get 8 and a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 808 from 879, we get 71.
Include the next digit (0) from the dividend after 71, then repeat: 710 / 101

Step 4:
When dividing 710 by 101, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 87.0
Subtracting 707 from 710 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 101

Moving on to step 5:
34 divided by 101 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 870.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 101

Step 6:
101 can be fit into 342 3 times, resulting in a remainder of 39.
The next digit of our result is 3. 
Result so far: 8703.0
Subtracting 303 from 342 leaves us with 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 101

Step 7:
When dividing 393 by 101, we get 3 with a remainder of 90.
Write down 3 as next digit of the result. 
Result so far: 87033.0
Deduct 303 from 393 and we're left with 90.
Include the next digit (9) from the dividend after 90, then repeat: 909 / 101

Going ahead to step 8:
When dividing 909 by 101, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 870339.0
If we take 909 away from 909, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
101 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 870339.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
101 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 870339.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 870339.0 and a remainder of 0.0.
