We look at the division of 451299 by 23 
Our goal is to divide 451299 by 23.

Advancing to step 1:
23 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 23

Let's proceed to step 2:
The number 23 fits into 45 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 23 from 45 and we're left with 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 23

On to step 3:
23 can be fit into 221 9 times, resulting in a remainder of 14.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 207 from 221 leaves us with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 23

Let's proceed to step 4:
23 can be fit into 142 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 196.0
If we take 138 away from 142, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 23

Advancing to step 5:
The number 23 fits into 49 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 1962.0
The remainder is 3 after subtracting 46 from 49.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 23

Moving on to step 6:
23 goes into 39 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 19621.0
Subtract 23 from 39 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 19621.6
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
If we divide 220 by 23, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 19621.69
Deduct 207 from 220 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 19621.695
The remainder is 15 after subtracting 115 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
If we divide 150 by 23, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 19621.6956
If we subtract 138 from 150, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 19621.69565
If we take 115 away from 120, we end up 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.

Let's proceed to step 12:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 19621.695652
If we subtract 46 from 50, we 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.

Let's proceed to step 13:
The number 23 fits into 40 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 19621.6956521
Subtracting 23 from 40 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 14:
If we divide 170 by 23, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 19621.69565217
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.

The quotient of the division is 19621.69565217, and the remainder is 9e-09.
