99404605 divided by 102 
The aim is to understand the frequency of 102 in 99404605.

On to step 1:
When dividing 9 by 102, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 102

Step 2:
99 divided by 102 is 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Fetch the next digit (4) from the dividend, attach it to 99 and continue: 994 / 102

Moving on to step 3:
If we divide 994 by 102, we get 9 and a remainder of 76.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 76 after subtracting 918 from 994.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 102

Moving on to step 4:
102 can be fit into 760 7 times, resulting in a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we take 714 away from 760, we end up with 46.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 102

Moving on to step 5:
If we divide 464 by 102, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 974.0
Deduct 408 from 464 and we're left with 56.
Append the next digit (6) from the dividend to 56 and continue with: 566 / 102

Going ahead to step 6:
102 can be fit into 566 5 times, resulting in a remainder of 56.
Record the quotient 5 as the next digit in the result. 
Result so far: 9745.0
Subtract 510 from 566 to get 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 102

Step 7:
The number 102 fits into 560 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 97455.0
Deduct 510 from 560 and we're left with 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 102

Let's proceed to step 8:
102 can be fit into 505 4 times, resulting in a remainder of 97.
The next digit of our result is 4. 
Result so far: 974554.0
Subtract 408 from 505 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 9:
102 can be fit into 970 9 times, resulting in a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 974554.9
Deduct 918 from 970 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
102 goes into 520 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 974554.95
If we take 510 away from 520, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
102 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 974554.95
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
When dividing 1000 by 102, we get 9 with a remainder of 82.
Put 9 as the next digit of the answer. 
Result so far: 974554.9509
If we take 918 away from 1000, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 13:
102 can be fit into 820 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 974554.95098
If we subtract 816 from 820, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
40 divided by 102 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 974554.95098
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
102 goes into 400 3 times with a remainder of 94.
Record the quotient 3 as the next digit in the result. 
Result so far: 974554.9509803
The remainder is 94 after subtracting 306 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 16:
102 can be fit into 940 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 974554.95098039
The remainder is 22 after subtracting 918 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 974554.95098039 and a remainder of 2.2e-08.
