We divide 405618 by 42
Let's see how many times 42 fits into 405618.

Advancing to step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 42

Advancing to step 2:
If we divide 40 by 42, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 42

Advancing to step 3:
405 divided by 42 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 27 after subtracting 378 from 405.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 42

On to step 4:
If we divide 276 by 42, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 96.0
If we take 252 away from 276, we end up with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 42

Moving on to step 5:
42 goes into 241 5 times with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 965.0
Subtract 210 from 241 to get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 42

Let's proceed to step 6:
42 goes into 318 7 times with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 9657.0
Subtract 294 from 318 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.

On to step 7:
If we divide 240 by 42, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 9657.5
Deduct 210 from 240 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 42, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 9657.57
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 9657.571
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.

Let's proceed to step 10:
When dividing 180 by 42, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 9657.5714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 9657.57142
Subtract 84 from 120 to 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.

Let's proceed to step 12:
When dividing 360 by 42, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 9657.571428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
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: 9657.5714285
Subtract 210 from 240 to 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.

Advancing 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: 9657.57142857
Subtracting 294 from 300 leaves us with 6.
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 outcome is 9657.57142857, with a leftover of 6e-09.
