We look at the division of 872810 by 23 
We want to figure out the number of times 872810 can be divided by 23.

On to step 1:
When dividing 8 by 23, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 23

Let's proceed to step 2:
23 can be fit into 87 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 69 from 87 leaves us with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 23

Moving on to step 3:
23 can be fit into 182 7 times, resulting in a remainder of 21.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 161 from 182 leaves us with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 23

On to step 4:
23 goes into 218 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 379.0
The remainder is 11 after subtracting 207 from 218.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 23

Moving on to step 5:
The number 23 fits into 111 4 times, leaving a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 3794.0
Subtract 92 from 111 to get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 23

Step 6:
23 goes into 190 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 37948.0
Subtract 184 from 190 to get 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:
23 goes into 60 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 37948.2
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:
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: 37948.26
If we take 138 away from 140, we end up with 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 9:
20 divided by 23 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 37948.26
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.

Moving on to step 10:
If we divide 200 by 23, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 37948.2608
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.

Moving on to step 11:
23 goes into 160 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 37948.26086
If we subtract 138 from 160, we 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.

Step 12:
When dividing 220 by 23, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 37948.260869
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.

On to step 13:
23 can be fit into 130 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 37948.2608695
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.

Going ahead to step 14:
23 can be fit into 150 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 37948.26086956
If we subtract 138 from 150, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 37948.26086956 with a remaining 1.2e-08.
