Let's divide 89670 by 23
The aim is to understand the frequency of 23 in 89670.

On to step 1:
When dividing 8 by 23, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 23

On to step 2:
89 divided by 23 is 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 20 after subtracting 69 from 89.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 23

Moving on to step 3:
The number 23 fits into 206 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Deduct 184 from 206 and we're left with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 23

Let's proceed to step 4:
23 goes into 227 9 times with a remainder of 20.
The next digit of our result is 9. 
Result so far: 389.0
Subtract 207 from 227 to get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 23

Moving on to step 5:
When dividing 200 by 23, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 3898.0
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 6:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 3898.6
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
220 divided by 23 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 3898.69
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
If we divide 130 by 23, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3898.695
Deduct 115 from 130 and we're left 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 9:
150 divided by 23 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 3898.6956
If we take 138 away from 150, we end up 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.

Advancing to step 10:
120 divided by 23 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3898.69565
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.

Step 11:
When dividing 50 by 23, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 3898.695652
If we take 46 away from 50, we end up 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.

Advancing to step 12:
40 divided by 23 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 3898.6956521
Subtracting 23 from 40 leaves us 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.

Going ahead to step 13:
When dividing 170 by 23, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 3898.69565217
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.

After the division, we end up with 3898.69565217 and a remainder of 9e-09.
