We divide 511144 by 42
Let's see how many times 42 fits into 511144.

Step 1:
42 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 42

Moving on to step 2:
51 divided by 42 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 42 from 51 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 42

Let's proceed to step 3:
When dividing 91 by 42, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 84 from 91 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 42

Step 4:
When dividing 71 by 42, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we subtract 42 from 71, we get 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 42

Step 5:
294 divided by 42 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 1217.0
The remainder is 0 after subtracting 294 from 294.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 42

On to step 6:
If we divide 4 by 42, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 12170.0
If we subtract 0 from 4, 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.

Step 7:
When dividing 40 by 42, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 12170.0
If we take 0 away from 40, we end up 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 8:
If we divide 400 by 42, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 12170.09
If we take 378 away from 400, 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 9:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 12170.095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 12170.0952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
42 goes into 160 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 12170.09523
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.

Moving on to step 12:
42 goes into 340 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 12170.095238
The remainder is 4 after subtracting 336 from 340.
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 13:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12170.095238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 12170.09523809
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.

The final result is 12170.09523809 with a remainder of 2.2e-08.
