We divide 31516549 by 23
The aim is to understand the frequency of 23 in 31516549.

Going ahead to step 1:
23 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 23

On to step 2:
When dividing 31 by 23, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 23 away from 31, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 23

On to step 3:
23 can be fit into 85 3 times, resulting in a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 69 from 85 leaves us with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 23

Let's proceed to step 4:
23 can be fit into 161 7 times, resulting in a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtract 161 from 161 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 23

Advancing to step 5:
23 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 1370.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 23

On to step 6:
If we divide 65 by 23, we get 2 and a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 13702.0
Subtract 46 from 65 to get 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 23

Going ahead to step 7:
The number 23 fits into 194 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 137028.0
Deduct 184 from 194 and we're left with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 23

Advancing to step 8:
109 divided by 23 is 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 1370284.0
Deduct 92 from 109 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 23 fits into 170 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 1370284.7
Subtracting 161 from 170 leaves us with 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.
The next digit of our result is 3. 
Result so far: 1370284.73
The remainder is 21 after subtracting 69 from 90.
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:
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: 1370284.739
If we subtract 207 from 210, we get 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.
Put 1 as the next digit of the answer. 
Result so far: 1370284.7391
Deduct 23 from 30 and we're left 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.

Going ahead to step 13:
When dividing 70 by 23, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1370284.73913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
23 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1370284.73913
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.

Let's proceed to step 15:
23 goes into 100 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1370284.7391304
Subtracting 92 from 100 leaves us 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.

Let's proceed to step 16:
When dividing 80 by 23, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 1370284.73913043
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.

The quotient of the division is 1370284.73913043, and the remainder is 1.1e-08.
