Let's divide 183989 by 23
The aim is to understand the frequency of 23 in 183989.

Moving on to step 1:
1 divided by 23 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 23

Moving on to step 2:
If we divide 18 by 23, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 23

Moving on to step 3:
23 goes into 183 7 times with a remainder of 22.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 161 from 183 and we're left with 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 23

Let's proceed to step 4:
23 can be fit into 229 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we subtract 207 from 229, we get 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 23

On to step 5:
If we divide 228 by 23, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 799.0
Subtracting 207 from 228 leaves us with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 23

On to step 6:
23 can be fit into 219 9 times, resulting in a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 7999.0
Deduct 207 from 219 and we're left 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.

Step 7:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 7999.5
Subtract 115 from 120 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 7999.52
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 23, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 7999.521
If we take 23 away from 40, we end up 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.

Advancing to step 10:
The number 23 fits into 170 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 7999.5217
The remainder is 9 after subtracting 161 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 7999.52173
Deduct 69 from 90 and we're left 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 12:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 7999.521739
Deduct 207 from 210 and we're left 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.

Moving on to step 13:
The number 23 fits into 30 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 7999.5217391
Subtracting 23 from 30 leaves us 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 14:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 7999.52173913
If we subtract 69 from 70, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 7999.52173913 with a remainder of 1e-09.
