42290806 divided by 424 
We want to figure out the number of times 42290806 can be divided by 424.

On to step 1:
4 divided by 424 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 424

On to step 2:
424 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 424

Step 3:
424 goes into 422 0 times with a remainder of 422.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 422, we get 422.
Fetch the next digit (9) from the dividend, attach it to 422 and continue: 4229 / 424

Moving on to step 4:
4229 divided by 424 is 9 with a remainder of 413.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 3816 from 4229 to get 413.
Append the next digit (0) from the dividend to 413 and continue with: 4130 / 424

On to step 5:
If we divide 4130 by 424, we get 9 and a remainder of 314.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 3816 from 4130 to get 314.
Bring next digit (8) of the dividend behind the 314 and repeat the process: 3148 / 424

Step 6:
If we divide 3148 by 424, we get 7 and a remainder of 180.
Write down 7 as next digit of the result. 
Result so far: 997.0
Subtracting 2968 from 3148 leaves us with 180.
Take the next digit (0) from the dividend and append it to 180, then repeat: 1800 / 424

Advancing to step 7:
424 can be fit into 1800 4 times, resulting in a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 9974.0
If we subtract 1696 from 1800, we get 104.
Fetch the next digit (6) from the dividend, attach it to 104 and continue: 1046 / 424

Let's proceed to step 8:
424 can be fit into 1046 2 times, resulting in a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 99742.0
Deduct 848 from 1046 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 9:
The number 424 fits into 1980 4 times, leaving a remainder of 284.
Put 4 as the next digit of the answer. 
Result so far: 99742.4
Deduct 1696 from 1980 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 10:
2840 divided by 424 is 6 with a remainder of 296.
Use 6 as the next digit of our solution. 
Result so far: 99742.46
If we take 2544 away from 2840, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 11:
When dividing 2960 by 424, we get 6 with a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 99742.466
If we take 2544 away from 2960, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The final outcome is 99742.466, with a leftover of 0.0416.
