We're dividing 877630 by 23 
The aim is to understand the frequency of 23 in 877630.

On to step 1:
8 divided by 23 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 23

Let's proceed to step 2:
87 divided by 23 is 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 69 away from 87, we end up with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 23

Step 3:
When dividing 187 by 23, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 184 from 187 and we're left with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 23

Step 4:
36 divided by 23 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 381.0
Deduct 23 from 36 and we're left with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 23

Let's proceed to step 5:
The number 23 fits into 133 5 times, leaving a remainder of 18.
The next digit of our result is 5. 
Result so far: 3815.0
Subtract 115 from 133 to get 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 23

On to step 6:
If we divide 180 by 23, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 38157.0
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 38157.8
The remainder is 6 after subtracting 184 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
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: 38157.82
If we take 46 away from 60, we end up 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.

On to step 9:
If we divide 140 by 23, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 38157.826
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.

Advancing to step 10:
The number 23 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 38157.826
If we subtract 0 from 20, we 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.

Step 11:
23 goes into 200 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 38157.82608
Deduct 184 from 200 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 38157.826086
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
When dividing 220 by 23, we get 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 38157.8260869
Deduct 207 from 220 and we're left 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.

Advancing to step 14:
When dividing 130 by 23, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 38157.82608695
If we take 115 away from 130, we end up 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.

In conclusion, the division gives 38157.82608695 with a balance of 1.5e-08.
