671370 ÷ 23 
We're looking to find how many times 23 goes into 671370.

Going ahead to step 1:
If we divide 6 by 23, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 23

Let's proceed to step 2:
If we divide 67 by 23, we get 2 and a remainder of 21.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 46 from 67 leaves us with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 23

Let's proceed to step 3:
When dividing 211 by 23, we get 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 207 from 211 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 23

On to step 4:
43 divided by 23 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 291.0
Subtracting 23 from 43 leaves us with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 23

On to step 5:
23 can be fit into 207 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 2919.0
The remainder is 0 after subtracting 207 from 207.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 23

Going ahead to step 6:
23 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 29190.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
0 divided by 23 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 29190.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 23 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29190.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 29190.0 with a balance of 0.0.
