Let's divide 132391 by 23
The aim is to understand the frequency of 23 in 132391.

Let's proceed to step 1:
23 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 23

Let's proceed to step 2:
The number 23 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 23

Going ahead to step 3:
23 goes into 132 5 times with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 115 from 132 to get 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 23

On to step 4:
When dividing 173 by 23, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 57.0
If we subtract 161 from 173, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 23

On to step 5:
23 can be fit into 129 5 times, resulting in a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 575.0
The remainder is 14 after subtracting 115 from 129.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 23

Moving on to step 6:
The number 23 fits into 141 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 5756.0
If we take 138 away from 141, 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.

Let's proceed to step 7:
23 goes into 30 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 5756.1
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 8:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 5756.13
If we take 69 away from 70, we end up 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.

Step 9:
10 divided by 23 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5756.13
Subtract 0 from 10 to 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.

Let's proceed to step 10:
When dividing 100 by 23, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 5756.1304
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.

On to step 11:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 5756.13043
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.

On to step 12:
When dividing 110 by 23, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 5756.130434
Subtracting 92 from 110 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
180 divided by 23 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 5756.1304347
If we subtract 161 from 180, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
23 goes into 190 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 5756.13043478
Subtract 184 from 190 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 5756.13043478, with a leftover of 6e-09.
