We look at the division of 870963 by 23 
We want to divide 870963 by 23.

Advancing to step 1:
8 divided by 23 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 23

Step 2:
If we divide 87 by 23, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 69 from 87 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 23

Going ahead to step 3:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 161 from 180 and we're left with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 23

Moving on to step 4:
23 goes into 199 8 times with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 378.0
Subtracting 184 from 199 leaves us with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 23

Going ahead to step 5:
23 can be fit into 156 6 times, resulting in a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 3786.0
If we take 138 away from 156, we end up with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 23

Let's proceed to step 6:
183 divided by 23 is 7 with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 37867.0
If we subtract 161 from 183, 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.

Advancing to step 7:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 37867.9
Subtracting 207 from 220 leaves us 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.

Going ahead to step 8:
If we divide 130 by 23, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 37867.95
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
If we divide 150 by 23, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 37867.956
Subtract 138 from 150 to 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.

Moving on to step 10:
23 goes into 120 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 37867.9565
Subtracting 115 from 120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
The number 23 fits into 50 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 37867.95652
If we subtract 46 from 50, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
When dividing 40 by 23, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 37867.956521
Deduct 23 from 40 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.

Moving on to step 13:
23 goes into 170 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 37867.9565217
If we take 161 away from 170, we end up 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.

On to step 14:
23 can be fit into 90 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 37867.95652173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 37867.95652173, and the remainder is 2.1e-08.
