619556 ÷ 23 
The aim is to understand the frequency of 23 in 619556.

Going ahead to step 1:
6 divided by 23 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 23

Advancing to step 2:
61 divided by 23 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 46 from 61 and we're left with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 23

On to step 3:
If we divide 159 by 23, we get 6 and a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 138 from 159 and we're left with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 23

Step 4:
The number 23 fits into 215 9 times, leaving a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 269.0
The remainder is 8 after subtracting 207 from 215.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 23

Advancing to step 5:
23 can be fit into 85 3 times, resulting in a remainder of 16.
The next digit of our result is 3. 
Result so far: 2693.0
Subtracting 69 from 85 leaves us with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 23

Advancing to step 6:
166 divided by 23 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 26937.0
The remainder is 5 after subtracting 161 from 166.
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 7:
50 divided by 23 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 26937.2
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.

Going ahead to step 8:
If we divide 40 by 23, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 26937.21
Subtract 23 from 40 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
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: 26937.217
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.

Step 10:
90 divided by 23 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 26937.2173
Subtracting 69 from 90 leaves us 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 11:
When dividing 210 by 23, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 26937.21739
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 12:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 26937.217391
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.

Advancing to step 13:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 26937.2173913
If we take 69 away from 70, we end up 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.

On to step 14:
10 divided by 23 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 26937.2173913
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 26937.2173913 with a remainder of 1e-08.
