440387 ÷ 42 
We're looking to find how many times 42 goes into 440387.

Let's proceed to step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 42

On to step 2:
42 can be fit into 44 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 44 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 42

Moving on to step 3:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 42

Let's proceed to step 4:
The number 42 fits into 203 4 times, leaving a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtract 168 from 203 to get 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 42

On to step 5:
42 can be fit into 358 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1048.0
Subtracting 336 from 358 leaves us with 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 42

Step 6:
The number 42 fits into 227 5 times, leaving a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 10485.0
The remainder is 17 after subtracting 210 from 227.
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 7:
The number 42 fits into 170 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 10485.4
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
42 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10485.4
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
200 divided by 42 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 10485.404
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
42 goes into 320 7 times with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 10485.4047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 10485.40476
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 10485.404761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
380 divided by 42 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 10485.4047619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
20 divided by 42 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10485.4047619
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 10485.4047619 with a remainder of 2e-08.
