We're dividing 450049 by 42 
We want to divide 450049 by 42.

Let's proceed to step 1:
4 divided by 42 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 42

Moving on to step 2:
45 divided by 42 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 42 from 45 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 42

On to step 3:
42 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 42

Moving on to step 4:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we subtract 294 from 300, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 42

Step 5:
42 can be fit into 64 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1071.0
If we subtract 42 from 64, we get 22.
Take the next digit (9) from the dividend and append it to 22, then repeat: 229 / 42

Step 6:
42 can be fit into 229 5 times, resulting in a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 10715.0
Subtracting 210 from 229 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
If we divide 190 by 42, we get 4 and a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 10715.4
Deduct 168 from 190 and we're left 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.

On to step 8:
42 goes into 220 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10715.45
Deduct 210 from 220 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.

Step 9:
100 divided by 42 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 10715.452
Subtract 84 from 100 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 10:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 10715.4523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10715.45238
If we take 336 away from 340, we end up 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.

Moving on to step 12:
When dividing 40 by 42, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10715.45238
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 10715.4523809
Deduct 378 from 400 and we're left 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.

Step 14:
If we divide 220 by 42, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 10715.45238095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 10715.45238095 with a balance of 1e-08.
