We look at the division of 42446673 by 423 
Our goal is to divide 42446673 by 423.

On to step 1:
If we divide 4 by 423, we get 0 and 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.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 423

Going ahead to step 2:
423 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 423

Advancing to step 3:
If we divide 424 by 423, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 423 from 424 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 423

Step 4:
423 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 423

Going ahead to step 5:
423 can be fit into 146 0 times, resulting in a remainder of 146.
The next digit of our result is 0. 
Result so far: 100.0
If we take 0 away from 146, we end up with 146.
Append the next digit (6) from the dividend to 146 and continue with: 1466 / 423

Let's proceed to step 6:
When dividing 1466 by 423, we get 3 with a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 1003.0
Subtract 1269 from 1466 to get 197.
Append the next digit (7) from the dividend to 197 and continue with: 1977 / 423

Let's proceed to step 7:
If we divide 1977 by 423, we get 4 and a remainder of 285.
Record the quotient 4 as the next digit in the result. 
Result so far: 10034.0
Subtract 1692 from 1977 to get 285.
Take the next digit (3) from the dividend and append it to 285, then repeat: 2853 / 423

On to step 8:
2853 divided by 423 is 6 with a remainder of 315.
The number 6 becomes the next digit in our result. 
Result so far: 100346.0
The remainder is 315 after subtracting 2538 from 2853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 9:
423 goes into 3150 7 times with a remainder of 189.
Record the quotient 7 as the next digit in the result. 
Result so far: 100346.7
Subtracting 2961 from 3150 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 10:
The number 423 fits into 1890 4 times, leaving a remainder of 198.
Record the quotient 4 as the next digit in the result. 
Result so far: 100346.74
Subtract 1692 from 1890 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 11:
423 can be fit into 1980 4 times, resulting in a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 100346.744
Subtracting 1692 from 1980 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

In conclusion, the division gives 100346.744 with a balance of 0.0288.
