801636 divided by 23 
The aim is to understand the frequency of 23 in 801636.

On to step 1:
8 divided by 23 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 23

Let's proceed to step 2:
When dividing 80 by 23, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 69 away from 80, we end up with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 23

Advancing to step 3:
23 can be fit into 111 4 times, resulting in a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtract 92 from 111 to get 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 23

On to step 4:
196 divided by 23 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 348.0
The remainder is 12 after subtracting 184 from 196.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 23

Step 5:
If we divide 123 by 23, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 3485.0
Subtract 115 from 123 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 23

Going ahead to step 6:
23 goes into 86 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 34853.0
The remainder is 17 after subtracting 69 from 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
170 divided by 23 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 34853.7
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.

Moving on to step 8:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 34853.73
Subtracting 69 from 90 leaves us 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.

On to step 9:
If we divide 210 by 23, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 34853.739
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 10:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 34853.7391
Deduct 23 from 30 and we're left 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 11:
If we divide 70 by 23, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 34853.73913
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.

Let's proceed to step 12:
When dividing 10 by 23, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 34853.73913
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
23 goes into 100 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 34853.7391304
If we subtract 92 from 100, we 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.

Let's proceed to step 14:
If we divide 80 by 23, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 34853.73913043
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 34853.73913043 and a remainder of 1.1e-08.
