Let's divide 225401 by 23
The aim is to understand the frequency of 23 in 225401.

Let's proceed to step 1:
23 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 23

Going ahead to step 2:
The number 23 fits into 22 0 times, leaving a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 23

On to step 3:
When dividing 225 by 23, we get 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 207 from 225 leaves us with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 23

Moving on to step 4:
23 goes into 184 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we subtract 184 from 184, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 23

Going ahead to step 5:
23 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 980.0
If we take 0 away from 0, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 23

Step 6:
If we divide 1 by 23, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 9800.0
Subtract 0 from 1 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.

Step 7:
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: 9800.0
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.

Let's proceed to step 8:
23 goes into 100 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 9800.04
Subtracting 92 from 100 leaves us 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.

Moving on to step 9:
23 goes into 80 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 9800.043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
If we divide 110 by 23, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 9800.0434
Subtracting 92 from 110 leaves us 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.

Let's proceed to step 11:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 9800.04347
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.

Going ahead to step 12:
If we divide 190 by 23, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 9800.043478
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.

Going ahead to step 13:
23 can be fit into 60 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 9800.0434782
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 9800.04347826
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 9800.04347826, and the remainder is 2e-09.
