We divide 409455 by 42
Let's see how many times 42 fits into 409455.

On 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
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 42

Let's proceed to step 2:
42 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 42

On to step 3:
42 can be fit into 409 9 times, resulting in a remainder of 31.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 378 from 409 to get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 42

Advancing to step 4:
42 goes into 314 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Deduct 294 from 314 and we're left with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 42

Step 5:
If we divide 205 by 42, we get 4 and a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 974.0
If we subtract 168 from 205, we get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 42

Moving on to step 6:
42 can be fit into 375 8 times, resulting in a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 9748.0
Subtracting 336 from 375 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
When dividing 390 by 42, we get 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 9748.9
Deduct 378 from 390 and we're left 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.

Advancing to step 8:
120 divided by 42 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 9748.92
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
When dividing 360 by 42, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 9748.928
Subtracting 336 from 360 leaves us with 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 10:
When dividing 240 by 42, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 9748.9285
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.

On to step 11:
If we divide 300 by 42, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 9748.92857
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.

Advancing to step 12:
If we divide 60 by 42, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 9748.928571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 9748.9285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
If we divide 120 by 42, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 9748.92857142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 9748.92857142, and the remainder is 3.6e-08.
