We look at the division of 405736 by 42 
We're looking to find how many times 42 goes into 405736.

Advancing to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 42

Going ahead to step 2:
40 divided by 42 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 42

On to step 3:
405 divided by 42 is 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 378 from 405 leaves us with 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 42

Let's proceed to step 4:
The number 42 fits into 277 6 times, leaving a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Subtracting 252 from 277 leaves us with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 42

Let's proceed to step 5:
The number 42 fits into 253 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 966.0
If we subtract 252 from 253, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 42

Let's proceed to step 6:
42 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 9660.0
If we subtract 0 from 16, we 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 7:
42 can be fit into 160 3 times, resulting in a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 9660.3
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 9660.38
Subtract 336 from 340 to 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.

On to step 9:
When dividing 40 by 42, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 9660.38
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.

On to step 10:
400 divided by 42 is 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 9660.3809
Subtract 378 from 400 to get 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 11:
42 goes into 220 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 9660.38095
If we take 210 away from 220, we end up 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.

On to step 12:
If we divide 100 by 42, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 9660.380952
Deduct 84 from 100 and we're left 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.

Advancing to step 13:
42 goes into 160 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 9660.3809523
Subtracting 126 from 160 leaves us 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 14:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 9660.38095238
Deduct 336 from 340 and we're left 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.

After the division, we end up with 9660.38095238 and a remainder of 4e-09.
