We're dividing 69789180 by 23 
The aim is to understand the frequency of 23 in 69789180.

Step 1:
The number 23 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 23

Moving on to step 2:
The number 23 fits into 69 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 69 from 69 leaves us with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 23

Going ahead to step 3:
7 divided by 23 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 23

Step 4:
23 goes into 78 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 303.0
Subtracting 69 from 78 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 23

On to step 5:
When dividing 99 by 23, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 3034.0
If we subtract 92 from 99, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 23

Moving on to step 6:
71 divided by 23 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 30343.0
Deduct 69 from 71 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 23

Step 7:
28 divided by 23 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 303431.0
The remainder is 5 after subtracting 23 from 28.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 23

Going ahead to step 8:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 3034312.0
Subtract 46 from 50 to 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.

Advancing to step 9:
40 divided by 23 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 3034312.1
Subtracting 23 from 40 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
If we divide 170 by 23, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 3034312.17
Deduct 161 from 170 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3034312.173
The remainder is 21 after subtracting 69 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 12:
23 goes into 210 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 3034312.1739
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
30 divided by 23 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 3034312.17391
If we take 23 away from 30, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
If we divide 70 by 23, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 3034312.173913
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 15:
When dividing 10 by 23, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3034312.173913
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
The number 23 fits into 100 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 3034312.17391304
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 3034312.17391304 with a balance of 8e-09.
