23931280 ÷ 902 
The aim is to understand the frequency of 902 in 23931280.

Moving on to step 1:
902 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 902

Advancing to step 2:
When dividing 23 by 902, we get 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 902

Moving on to step 3:
If we divide 239 by 902, we get 0 and a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 239 leaves us with 239.
Take the next digit (3) from the dividend and append it to 239, then repeat: 2393 / 902

On to step 4:
902 goes into 2393 2 times with a remainder of 589.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1804 from 2393 to get 589.
Fetch the next digit (1) from the dividend, attach it to 589 and continue: 5891 / 902

Moving on to step 5:
902 can be fit into 5891 6 times, resulting in a remainder of 479.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 5412 from 5891 and we're left with 479.
Grab the next digit (2) from the dividend, add it to 479, then carry on: 4792 / 902

Moving on to step 6:
When dividing 4792 by 902, we get 5 with a remainder of 282.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
If we subtract 4510 from 4792, we get 282.
Bring next digit (8) of the dividend behind the 282 and repeat the process: 2828 / 902

On to step 7:
2828 divided by 902 is 3 with a remainder of 122.
Use 3 as the next digit of our solution. 
Result so far: 2653.0
Deduct 2706 from 2828 and we're left with 122.
Append the next digit (0) from the dividend to 122 and continue with: 1220 / 902

Moving on to step 8:
The number 902 fits into 1220 1 times, leaving a remainder of 318.
Write down 1 as next digit of the result. 
Result so far: 26531.0
The remainder is 318 after subtracting 902 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 9:
When dividing 3180 by 902, we get 3 with a remainder of 474.
Record the quotient 3 as the next digit in the result. 
Result so far: 26531.3
If we subtract 2706 from 3180, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Moving on to step 10:
When dividing 4740 by 902, we get 5 with a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 26531.35
The remainder is 230 after subtracting 4510 from 4740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 11:
2300 divided by 902 is 2 with a remainder of 496.
The next digit of our result is 2. 
Result so far: 26531.352
Deduct 1804 from 2300 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 12:
The number 902 fits into 4960 5 times, leaving a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 26531.3525
Deduct 4510 from 4960 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 13:
4500 divided by 902 is 4 with a remainder of 892.
Write down 4 as next digit of the result. 
Result so far: 26531.35254
Deduct 3608 from 4500 and we're left with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Step 14:
If we divide 8920 by 902, we get 9 and a remainder of 802.
Record the quotient 9 as the next digit in the result. 
Result so far: 26531.352549
Subtracting 8118 from 8920 leaves us with 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Let's proceed to step 15:
When dividing 8020 by 902, we get 8 with a remainder of 804.
The number 8 becomes the next digit in our result. 
Result so far: 26531.3525498
The remainder is 804 after subtracting 7216 from 8020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Moving on to step 16:
902 can be fit into 8040 8 times, resulting in a remainder of 824.
Record the quotient 8 as the next digit in the result. 
Result so far: 26531.35254988
Deduct 7216 from 8040 and we're left with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

In conclusion, the division gives 26531.35254988 with a balance of 8.24e-07.
