39681 divided by 23 
The aim is to understand the frequency of 23 in 39681.

On to step 1:
The number 23 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 23

Advancing to step 2:
23 can be fit into 39 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 23 from 39, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 23

Let's proceed to step 3:
23 goes into 166 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 161 away from 166, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 23

On to step 4:
The number 23 fits into 58 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
The remainder is 12 after subtracting 46 from 58.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 23

Moving on to step 5:
23 goes into 121 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 1725.0
If we take 115 away from 121, we end up 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 6:
The number 23 fits into 60 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 1725.2
If we subtract 46 from 60, we 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.

Advancing to step 7:
140 divided by 23 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 1725.26
Subtract 138 from 140 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 23 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1725.26
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.

Let's proceed to step 9:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1725.2608
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 1725.26086
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.

Let's proceed to step 11:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 1725.260869
If we take 207 away from 220, we end up 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.

Going ahead to step 12:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1725.2608695
Deduct 115 from 130 and we're left 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.

Advancing to step 13:
When dividing 150 by 23, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 1725.26086956
Subtracting 138 from 150 leaves us with 12.
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 outcome is 1725.26086956, with a leftover of 1.2e-08.
