Let's divide 515994 by 23
We want to figure out the number of times 515994 can be divided by 23.

On to step 1:
The number 23 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 23

On to step 2:
When dividing 51 by 23, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 46 from 51 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 23

Advancing to step 3:
23 can be fit into 55 2 times, resulting in a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 46 from 55 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 23

Step 4:
If we divide 99 by 23, we get 4 and a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 224.0
Subtracting 92 from 99 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 23

Advancing to step 5:
The number 23 fits into 79 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 2243.0
Subtract 69 from 79 to get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 23

On to step 6:
The number 23 fits into 104 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 22434.0
Deduct 92 from 104 and we're left 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:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 22434.5
If we subtract 115 from 120, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 22434.52
Subtract 46 from 50 to 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.

Advancing to step 9:
40 divided by 23 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 22434.521
Subtract 23 from 40 to 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.

On to step 10:
170 divided by 23 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 22434.5217
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 11:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 22434.52173
Deduct 69 from 90 and we're left with 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:
The number 23 fits into 210 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 22434.521739
If we subtract 207 from 210, we 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.

Advancing to step 13:
If we divide 30 by 23, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 22434.5217391
If we take 23 away from 30, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
23 goes into 70 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 22434.52173913
If we take 69 away from 70, we end up 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 22434.52173913 with a balance of 1e-09.
