726987 ÷ 23 
The aim is to understand the frequency of 23 in 726987.

Let's proceed to step 1:
If we divide 7 by 23, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 23

On to step 2:
If we divide 72 by 23, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 69 from 72 and we're left with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 23

On to step 3:
The number 23 fits into 36 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 13 after subtracting 23 from 36.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 23

Moving on to step 4:
The number 23 fits into 139 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
Subtract 138 from 139 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 23

Moving on to step 5:
If we divide 18 by 23, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 3160.0
If we subtract 0 from 18, we get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 23

On to step 6:
187 divided by 23 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 31608.0
Deduct 184 from 187 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.

On to step 7:
23 goes into 30 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 31608.1
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.

On to step 8:
If we divide 70 by 23, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 31608.13
Subtract 69 from 70 to 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.

Going ahead to step 9:
23 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 31608.13
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 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: 31608.1304
Deduct 92 from 100 and we're left 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.

Let's proceed to step 11:
The number 23 fits into 80 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 31608.13043
If we take 69 away from 80, we end up 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.

Step 12:
If we divide 110 by 23, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 31608.130434
Deduct 92 from 110 and we're left 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.
Write down 7 as next digit of the result. 
Result so far: 31608.1304347
Subtract 161 from 180 to 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.

Let's proceed to step 14:
23 can be fit into 190 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 31608.13043478
If we subtract 184 from 190, we 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.

In conclusion, the division gives 31608.13043478 with a balance of 6e-09.
