We divide 679809 by 23
The aim is to understand the frequency of 23 in 679809.

On to step 1:
The number 23 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 23

Step 2:
67 divided by 23 is 2 with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 21 after subtracting 46 from 67.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 23

Going ahead to step 3:
When dividing 219 by 23, we get 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 207 from 219 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 23

Going ahead to step 4:
The number 23 fits into 128 5 times, leaving a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 295.0
If we subtract 115 from 128, we get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 23

Step 5:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2955.0
Deduct 115 from 130 and we're left with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 23

Advancing to step 6:
23 can be fit into 159 6 times, resulting in a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 29556.0
If we take 138 away from 159, 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.

Moving on to step 7:
23 goes into 210 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 29556.9
If we take 207 away from 210, we end up 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.

Step 8:
If we divide 30 by 23, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 29556.91
Subtracting 23 from 30 leaves us 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.

Moving on to step 9:
23 goes into 70 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 29556.913
If we subtract 69 from 70, we 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.

On to step 10:
If we divide 10 by 23, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 29556.913
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.

Step 11:
23 goes into 100 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 29556.91304
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.

Going ahead to step 12:
80 divided by 23 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 29556.913043
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.

Going ahead to step 13:
110 divided by 23 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 29556.9130434
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.

Advancing to step 14:
23 goes into 180 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 29556.91304347
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.

After the division, we end up with 29556.91304347 and a remainder of 1.9e-08.
