We divide 515100 by 23
Let's see how many times 23 fits into 515100.

Step 1:
If we divide 5 by 23, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 23

Advancing to step 2:
23 can be fit into 51 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 46 from 51 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 23

Moving on to step 3:
23 goes into 55 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 9 after subtracting 46 from 55.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 23

Advancing to step 4:
The number 23 fits into 91 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 223.0
If we take 69 away from 91, we end up with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 23

Going ahead to step 5:
When dividing 220 by 23, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 2239.0
Subtracting 207 from 220 leaves us with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 23

Moving on to step 6:
When dividing 130 by 23, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 22395.0
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 23, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 22395.6
Deduct 138 from 150 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 8:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 22395.65
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.

Advancing to step 9:
When dividing 50 by 23, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 22395.652
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.

Step 10:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 22395.6521
The remainder is 17 after subtracting 23 from 40.
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 11:
170 divided by 23 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 22395.65217
Deduct 161 from 170 and we're left 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 12:
When dividing 90 by 23, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 22395.652173
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.

Moving on to step 13:
23 goes into 210 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 22395.6521739
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 14:
30 divided by 23 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 22395.65217391
Subtracting 23 from 30 leaves us 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.

The quotient of the division is 22395.65217391, and the remainder is 7e-09.
