457392 ÷ 23 
We want to divide 457392 by 23.

Going ahead to step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 23

Let's proceed to step 2:
If we divide 45 by 23, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 23 from 45 to get 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 23

On to step 3:
If we divide 227 by 23, we get 9 and a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 207 away from 227, we end up with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 23

On to step 4:
23 can be fit into 203 8 times, resulting in a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 198.0
If we subtract 184 from 203, we get 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 23

Let's proceed to step 5:
If we divide 199 by 23, we get 8 and a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 1988.0
Subtract 184 from 199 to get 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 23

Let's proceed to step 6:
If we divide 152 by 23, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 19886.0
Subtracting 138 from 152 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 19886.6
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
20 divided by 23 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 19886.6
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 23, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 19886.608
The remainder is 16 after subtracting 184 from 200.
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 10:
23 can be fit into 160 6 times, resulting in a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 19886.6086
If we take 138 away from 160, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 19886.60869
Subtracting 207 from 220 leaves us 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.

Advancing to step 12:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 19886.608695
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 19886.6086956
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 14:
120 divided by 23 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 19886.60869565
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 19886.60869565 with a remaining 5e-09.
