We're dividing 671980 by 23 
We want to figure out the number of times 671980 can be divided by 23.

Moving on to step 1:
6 divided by 23 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 23

Step 2:
23 can be fit into 67 2 times, resulting in a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 46 away from 67, we end up with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 23

On to step 3:
When dividing 211 by 23, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 207 from 211 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 23

Going ahead to step 4:
23 can be fit into 49 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 292.0
If we subtract 46 from 49, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 23

Going ahead to step 5:
The number 23 fits into 38 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 2921.0
Subtracting 23 from 38 leaves us with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 23

Moving on to step 6:
When dividing 150 by 23, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 29216.0
If we take 138 away from 150, we end up 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.

On to step 7:
120 divided by 23 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 29216.5
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.

On to step 8:
If we divide 50 by 23, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 29216.52
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 23, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 29216.521
If we subtract 23 from 40, we get 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 10:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 29216.5217
Subtracting 161 from 170 leaves us 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 11:
When dividing 90 by 23, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 29216.52173
If we subtract 69 from 90, we 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.

Advancing to step 12:
When dividing 210 by 23, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 29216.521739
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
If we divide 30 by 23, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 29216.5217391
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
If we divide 70 by 23, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 29216.52173913
Deduct 69 from 70 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 29216.52173913 with a balance of 1e-09.
