We divide 201645 by 23
The aim is to understand the frequency of 23 in 201645.

Advancing to step 1:
The number 23 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 23

Moving on to step 2:
If we divide 20 by 23, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 23

Advancing to step 3:
23 can be fit into 201 8 times, resulting in a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 184 from 201 and we're left with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 23

On to step 4:
176 divided by 23 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtracting 161 from 176 leaves us with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 23

Going ahead to step 5:
If we divide 154 by 23, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 876.0
If we take 138 away from 154, we end up with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 23

Step 6:
If we divide 165 by 23, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 8767.0
If we subtract 161 from 165, we 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.

Moving on to step 7:
23 goes into 40 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 8767.1
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.

Moving on to step 8:
170 divided by 23 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 8767.17
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
If we divide 90 by 23, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 8767.173
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
When dividing 210 by 23, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 8767.1739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 8767.17391
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.

On to step 12:
23 goes into 70 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 8767.173913
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.

Advancing to step 13:
The number 23 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8767.173913
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 23, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 8767.17391304
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.

After the division, we end up with 8767.17391304 and a remainder of 8e-09.
