We look at the division of 498438 by 23 
We want to figure out the number of times 498438 can be divided by 23.

Step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 23

Step 2:
When dividing 49 by 23, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 46 from 49 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 23

Step 3:
When dividing 38 by 23, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 23 from 38 leaves us with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 23

On to step 4:
The number 23 fits into 154 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 216.0
Deduct 138 from 154 and we're left with 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 23

Going ahead to step 5:
The number 23 fits into 163 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 2167.0
Subtract 161 from 163 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 23

On to step 6:
When dividing 28 by 23, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 21671.0
If we take 23 away from 28, 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.

On to step 7:
50 divided by 23 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 21671.2
Deduct 46 from 50 and we're left with 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 8:
40 divided by 23 is 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 21671.21
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.

Let's proceed to step 9:
When dividing 170 by 23, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 21671.217
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.

Moving on to step 10:
If we divide 90 by 23, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 21671.2173
Subtract 69 from 90 to get 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 11:
When dividing 210 by 23, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 21671.21739
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.

Going ahead to step 12:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 21671.217391
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.

Moving on to step 13:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 21671.2173913
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
23 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 21671.2173913
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 21671.2173913, with a leftover of 1e-08.
