456144 ÷ 42 
Our goal is to divide 456144 by 42.

Let's proceed to step 1:
4 divided by 42 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 42

On to step 2:
42 can be fit into 45 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 42 away from 45, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 42

Step 3:
36 divided by 42 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 36 to get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 42

Moving on to step 4:
42 goes into 361 8 times with a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 336 away from 361, we end up with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 42

Step 5:
42 goes into 254 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1086.0
Deduct 252 from 254 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 42

Advancing to step 6:
24 divided by 42 is 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 10860.0
The remainder is 24 after subtracting 0 from 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 10860.5
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 10860.57
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 10860.571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
180 divided by 42 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 10860.5714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
If we divide 120 by 42, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 10860.57142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 10860.571428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
The number 42 fits into 240 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 10860.5714285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
42 goes into 300 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 10860.57142857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 10860.57142857 with a remainder of 6e-09.
