Let's divide 86635 by 23
The aim is to understand the frequency of 23 in 86635.

Let's proceed to step 1:
When dividing 8 by 23, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 23

Let's proceed to step 2:
86 divided by 23 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 69 from 86 and we're left with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 23

Going ahead to step 3:
If we divide 176 by 23, we get 7 and a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 161 from 176 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 23

Let's proceed to step 4:
23 can be fit into 153 6 times, resulting in a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 376.0
If we subtract 138 from 153, we get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 23

Let's proceed to step 5:
The number 23 fits into 155 6 times, leaving a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 3766.0
The remainder is 17 after subtracting 138 from 155.
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 6:
23 can be fit into 170 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 3766.7
If we take 161 away from 170, we end up 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.

Moving on to step 7:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 3766.73
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.

Going ahead to step 8:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 3766.739
If we take 207 away from 210, we end up 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.

Going ahead to step 9:
When dividing 30 by 23, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 3766.7391
If we subtract 23 from 30, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
70 divided by 23 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3766.73913
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.

Moving on to step 11:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3766.73913
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.

Advancing to step 12:
If we divide 100 by 23, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3766.7391304
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3766.73913043
Subtracting 69 from 80 leaves us with 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 3766.73913043 and a remainder of 1.1e-08.
