We divide 31530815 by 102
The aim is to understand the frequency of 102 in 31530815.

Step 1:
102 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 102

Moving on to step 2:
31 divided by 102 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 102

On to step 3:
315 divided by 102 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 306 from 315 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 102

Going ahead to step 4:
If we divide 93 by 102, we get 0 and a remainder of 93.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 93 after subtracting 0 from 93.
Include the next digit (0) from the dividend after 93, then repeat: 930 / 102

Advancing to step 5:
If we divide 930 by 102, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 309.0
The remainder is 12 after subtracting 918 from 930.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 102

Advancing to step 6:
When dividing 128 by 102, we get 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 3091.0
Subtract 102 from 128 to get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 102

Moving on to step 7:
102 can be fit into 261 2 times, resulting in a remainder of 57.
The next digit of our result is 2. 
Result so far: 30912.0
Subtract 204 from 261 to get 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 102

Step 8:
When dividing 575 by 102, we get 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 309125.0
If we subtract 510 from 575, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
650 divided by 102 is 6 with a remainder of 38.
The next digit of our result is 6. 
Result so far: 309125.6
The remainder is 38 after subtracting 612 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
If we divide 380 by 102, we get 3 and a remainder of 74.
Use 3 as the next digit of our solution. 
Result so far: 309125.63
Subtracting 306 from 380 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
102 can be fit into 740 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 309125.637
If we subtract 714 from 740, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
260 divided by 102 is 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 309125.6372
If we subtract 204 from 260, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
If we divide 560 by 102, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 309125.63725
If we take 510 away from 560, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
The number 102 fits into 500 4 times, leaving a remainder of 92.
Put 4 as the next digit of the answer. 
Result so far: 309125.637254
Deduct 408 from 500 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 15:
102 can be fit into 920 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 309125.6372549
Deduct 918 from 920 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 16:
102 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 309125.6372549
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 309125.6372549 and a remainder of 2e-08.
