Let's divide 201937 by 23
The aim is to understand the frequency of 23 in 201937.

Going ahead to step 1:
23 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 23

Advancing to step 2:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 23

Let's proceed to step 3:
If we divide 201 by 23, we get 8 and a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 184 away from 201, we end up with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 23

Advancing to step 4:
If we divide 179 by 23, we get 7 and a remainder of 18.
The next digit of our result is 7. 
Result so far: 87.0
If we subtract 161 from 179, we get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 23

Step 5:
23 goes into 183 7 times with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 877.0
The remainder is 22 after subtracting 161 from 183.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 23

Advancing to step 6:
If we divide 227 by 23, we get 9 and a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 8779.0
Subtract 207 from 227 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8779.8
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
The number 23 fits into 160 6 times, leaving a remainder of 22.
The next digit of our result is 6. 
Result so far: 8779.86
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
If we divide 220 by 23, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 8779.869
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
If we divide 130 by 23, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 8779.8695
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
If we divide 150 by 23, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 8779.86956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
If we divide 120 by 23, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 8779.869565
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 8779.8695652
If we subtract 46 from 50, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
If we divide 40 by 23, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 8779.86956521
If we subtract 23 from 40, we 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.

Our division results in 8779.86956521 with a remaining 1.7e-08.
