201190 ÷ 23 
The aim is to understand the frequency of 23 in 201190.

Going ahead to 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 (0) from the dividend, add it to 2, then carry on: 20 / 23

Going ahead to step 2:
23 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 23

Step 3:
23 goes into 201 8 times with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 184 away from 201, we end up with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 23

Let's proceed to step 4:
When dividing 171 by 23, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 87.0
Subtracting 161 from 171 leaves us with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 23

Moving on to step 5:
The number 23 fits into 109 4 times, leaving a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 874.0
The remainder is 17 after subtracting 92 from 109.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 23

On to step 6:
If we divide 170 by 23, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 8747.0
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 7:
23 goes into 90 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 8747.3
Deduct 69 from 90 and we're left 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.

Advancing to step 8:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 8747.39
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
The number 23 fits into 30 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 8747.391
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.

Advancing to step 10:
The number 23 fits into 70 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 8747.3913
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.

Advancing to step 11:
When dividing 10 by 23, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 8747.3913
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.

On to step 12:
23 goes into 100 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 8747.391304
If we take 92 away from 100, we end up 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.

Step 13:
80 divided by 23 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 8747.3913043
Deduct 69 from 80 and we're left 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 14:
The number 23 fits into 110 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 8747.39130434
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.

The final result is 8747.39130434 with a remainder of 1.8e-08.
