We divide 724871 by 23
The aim is to understand the frequency of 23 in 724871.

Going ahead to step 1:
7 divided by 23 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 23

Moving 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
If we subtract 69 from 72, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 23

Step 3:
34 divided by 23 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 23 from 34 to get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 23

Going ahead to step 4:
118 divided by 23 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 315.0
Subtracting 115 from 118 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 23

Going ahead to step 5:
23 goes into 37 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 3151.0
If we take 23 away from 37, we end up with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 23

On to step 6:
141 divided by 23 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 31516.0
Subtract 138 from 141 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
23 goes into 30 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 31516.1
The remainder is 7 after subtracting 23 from 30.
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:
If we divide 70 by 23, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 31516.13
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.

Let's proceed to step 9:
If we divide 10 by 23, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 31516.13
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.

Step 10:
When dividing 100 by 23, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 31516.1304
If we take 92 away from 100, we end up 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:
80 divided by 23 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 31516.13043
Subtract 69 from 80 to 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.

Step 12:
110 divided by 23 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 31516.130434
If we take 92 away from 110, we end up 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.

Advancing to step 13:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 31516.1304347
Subtracting 161 from 180 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
23 goes into 190 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 31516.13043478
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.

After the division, we end up with 31516.13043478 and a remainder of 6e-09.
