225574 divided by 23 
The aim is to understand the frequency of 23 in 225574.

Step 1:
The number 23 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 23

Let's proceed to step 2:
The number 23 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 23

Moving on to step 3:
225 divided by 23 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 18 after subtracting 207 from 225.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 23

Step 4:
If we divide 185 by 23, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Deduct 184 from 185 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 23

Going ahead to step 5:
If we divide 17 by 23, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 980.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 23

Let's proceed to step 6:
174 divided by 23 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 9807.0
The remainder is 13 after subtracting 161 from 174.
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 7:
130 divided by 23 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 9807.5
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.

Advancing to step 8:
150 divided by 23 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 9807.56
Deduct 138 from 150 and we're left 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.

Let's proceed to step 9:
If we divide 120 by 23, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 9807.565
If we take 115 away from 120, we end up 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.

Moving on to step 10:
If we divide 50 by 23, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 9807.5652
If we subtract 46 from 50, we get 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 11:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 9807.56521
If we take 23 away from 40, we end up 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 12:
23 goes into 170 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 9807.565217
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.

Advancing to step 13:
When dividing 90 by 23, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 9807.5652173
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
23 goes into 210 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 9807.56521739
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.

The quotient of the division is 9807.56521739, and the remainder is 3e-09.
