We look at the division of 750712 by 23 
The aim is to understand the frequency of 23 in 750712.

Advancing to step 1:
23 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 23

Step 2:
75 divided by 23 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 69 from 75 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 23

Going ahead to step 3:
60 divided by 23 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 14 after subtracting 46 from 60.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 23

Step 4:
If we divide 147 by 23, we get 6 and a remainder of 9.
The next digit of our result is 6. 
Result so far: 326.0
Subtracting 138 from 147 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 23

On to step 5:
If we divide 91 by 23, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 3263.0
The remainder is 22 after subtracting 69 from 91.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 23

Let's proceed to step 6:
When dividing 222 by 23, we get 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 32639.0
Subtracting 207 from 222 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.

Going ahead to step 7:
When dividing 150 by 23, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 32639.6
If we subtract 138 from 150, we get 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 8:
If we divide 120 by 23, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 32639.65
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 32639.652
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.

Moving on to step 10:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 32639.6521
The remainder is 17 after subtracting 23 from 40.
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 11:
If we divide 170 by 23, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 32639.65217
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 32639.652173
If we subtract 69 from 90, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
23 goes into 210 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 32639.6521739
Subtracting 207 from 210 leaves us 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 14:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 32639.65217391
If we take 23 away from 30, we end up 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.

After the division, we end up with 32639.65217391 and a remainder of 7e-09.
