Let's divide 520517 by 23
We want to divide 520517 by 23.

On to step 1:
If we divide 5 by 23, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 23

On to step 2:
When dividing 52 by 23, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 46 from 52, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 23

Going ahead to step 3:
The number 23 fits into 60 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 46 from 60 and we're left with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 23

Advancing to step 4:
If we divide 145 by 23, we get 6 and a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 226.0
Subtracting 138 from 145 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 23

Let's proceed to step 5:
23 can be fit into 71 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 2263.0
If we subtract 69 from 71, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 23

Let's proceed to step 6:
When dividing 27 by 23, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 22631.0
The remainder is 4 after subtracting 23 from 27.
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 7:
23 goes into 40 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 22631.1
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.

Advancing to step 8:
If we divide 170 by 23, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 22631.17
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 22631.173
If we take 69 away from 90, we end up 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.

On to step 10:
23 can be fit into 210 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 22631.1739
If we take 207 away from 210, we end up with 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 11:
If we divide 30 by 23, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 22631.17391
If we subtract 23 from 30, we 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.

Going ahead to step 12:
The number 23 fits into 70 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 22631.173913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
If we divide 10 by 23, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 22631.173913
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 23 fits into 100 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 22631.17391304
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 22631.17391304 and a remainder of 8e-09.
