We divide 807145 by 23
The aim is to understand the frequency of 23 in 807145.

On to step 1:
The number 23 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 23

Advancing to step 2:
23 goes into 80 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 69 from 80, we get 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 23

Advancing to step 3:
23 can be fit into 117 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we take 115 away from 117, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 23

Advancing to step 4:
21 divided by 23 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 350.0
If we subtract 0 from 21, we get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 23

Going ahead to step 5:
When dividing 214 by 23, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 3509.0
Deduct 207 from 214 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 23

Let's proceed to step 6:
The number 23 fits into 75 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 35093.0
Deduct 69 from 75 and we're left 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.

Advancing to step 7:
When dividing 60 by 23, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 35093.2
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
When dividing 140 by 23, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 35093.26
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.

Step 9:
When dividing 20 by 23, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 35093.26
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.

On to step 10:
23 goes into 200 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 35093.2608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
23 goes into 160 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 35093.26086
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
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: 35093.260869
If we take 207 away from 220, we end up with 13.
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 13:
If we divide 130 by 23, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 35093.2608695
Deduct 115 from 130 and we're left 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 14:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 35093.26086956
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 35093.26086956 with a remainder of 1.2e-08.
