We divide 857013 by 23
The aim is to understand the frequency of 23 in 857013.

Advancing to step 1:
8 divided by 23 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 23

Moving on to step 2:
When dividing 85 by 23, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 69 from 85, we get 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 23

Going ahead to step 3:
If we divide 167 by 23, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 161 from 167 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 23

Advancing to step 4:
23 goes into 60 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 372.0
Subtract 46 from 60 to get 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 23

Going ahead to step 5:
23 goes into 141 6 times with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 3726.0
Subtracting 138 from 141 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 23

Moving on to step 6:
33 divided by 23 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 37261.0
Subtract 23 from 33 to 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.

Let's proceed to step 7:
23 goes into 100 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 37261.4
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
23 goes into 80 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 37261.43
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 9:
23 goes into 110 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 37261.434
Subtract 92 from 110 to get 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 10:
180 divided by 23 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 37261.4347
Deduct 161 from 180 and we're left 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.

Advancing to step 11:
If we divide 190 by 23, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 37261.43478
If we take 184 away from 190, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 37261.434782
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
23 can be fit into 140 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 37261.4347826
Subtract 138 from 140 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
20 divided by 23 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 37261.4347826
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 37261.4347826 with a remaining 2e-08.
