345729 divided by 23 
The aim is to understand the frequency of 23 in 345729.

Going ahead to step 1:
23 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 23

Advancing to step 2:
When dividing 34 by 23, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 23 away from 34, we end up with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 23

Advancing to step 3:
The number 23 fits into 115 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 0 after subtracting 115 from 115.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 23

Let's proceed to step 4:
The number 23 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 23

Step 5:
23 goes into 72 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 1503.0
Subtracting 69 from 72 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 23

Step 6:
39 divided by 23 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 15031.0
If we subtract 23 from 39, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 15031.6
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 15031.69
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
23 goes into 130 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 15031.695
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
23 can be fit into 150 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 15031.6956
Subtracting 138 from 150 leaves us 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.

Moving on to step 11:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 15031.69565
Deduct 115 from 120 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
If we divide 50 by 23, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 15031.695652
Subtracting 46 from 50 leaves us 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.

On to step 13:
23 goes into 40 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 15031.6956521
Deduct 23 from 40 and we're left 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 14:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 15031.69565217
Deduct 161 from 170 and we're left 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.

Our division results in 15031.69565217 with a remaining 9e-09.
