We look at the division of 898685 by 23 
The aim is to understand the frequency of 23 in 898685.

Going ahead to step 1:
23 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 23

Advancing to step 2:
If we divide 89 by 23, we get 3 and a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 69 from 89 and we're left with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 23

On to step 3:
The number 23 fits into 208 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 207 from 208 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 23

Going ahead to step 4:
23 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 390.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 23

Advancing to step 5:
When dividing 168 by 23, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 3907.0
The remainder is 7 after subtracting 161 from 168.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 23

Going ahead to step 6:
23 can be fit into 75 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 39073.0
Subtracting 69 from 75 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 23 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 39073.2
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
140 divided by 23 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 39073.26
Deduct 138 from 140 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.

Advancing to step 9:
The number 23 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 39073.26
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
23 goes into 200 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 39073.2608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 23, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 39073.26086
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 39073.260869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
If we divide 130 by 23, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 39073.2608695
If we take 115 away from 130, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 39073.26086956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 39073.26086956 with a remainder of 1.2e-08.
