We divide 439560 by 23
The aim is to understand the frequency of 23 in 439560.

Let's proceed to step 1:
23 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 23

On to step 2:
The number 23 fits into 43 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 23 away from 43, we end up with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 23

Advancing to step 3:
23 goes into 209 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 207 from 209, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 23

Advancing to step 4:
If we divide 25 by 23, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
If we subtract 23 from 25, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 23

Advancing to step 5:
The number 23 fits into 26 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1911.0
Subtracting 23 from 26 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 23

Advancing to step 6:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 19111.0
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 23 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 19111.3
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
23 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 19111.3
If we take 0 away from 10, we end up 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.

Moving on to step 9:
23 goes into 100 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 19111.304
Deduct 92 from 100 and we're left 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.

Advancing to step 10:
If we divide 80 by 23, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 19111.3043
If we take 69 away from 80, we end up with 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 11:
23 goes into 110 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 19111.30434
Deduct 92 from 110 and we're left 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.

Moving on to step 12:
23 goes into 180 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 19111.304347
Deduct 161 from 180 and we're left 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.

Let's proceed to step 13:
If we divide 190 by 23, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 19111.3043478
If we take 184 away from 190, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
23 goes into 60 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 19111.30434782
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 19111.30434782, and the remainder is 1.4e-08.
