Let's divide 42840402 by 844
Our goal is to divide 42840402 by 844.

On to step 1:
844 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 844

Step 2:
If we divide 42 by 844, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 844

Step 3:
844 goes into 428 0 times with a remainder of 428.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 428, we get 428.
Include the next digit (4) from the dividend after 428, then repeat: 4284 / 844

Going ahead to step 4:
844 goes into 4284 5 times with a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4220 from 4284 to get 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 844

Step 5:
The number 844 fits into 640 0 times, leaving a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 640 after subtracting 0 from 640.
Grab the next digit (4) from the dividend, add it to 640, then carry on: 6404 / 844

On to step 6:
If we divide 6404 by 844, we get 7 and a remainder of 496.
Use 7 as the next digit of our solution. 
Result so far: 507.0
Subtract 5908 from 6404 to get 496.
Take the next digit (0) from the dividend and append it to 496, then repeat: 4960 / 844

Moving on to step 7:
4960 divided by 844 is 5 with a remainder of 740.
The number 5 becomes the next digit in our result. 
Result so far: 5075.0
If we take 4220 away from 4960, we end up with 740.
Fetch the next digit (2) from the dividend, attach it to 740 and continue: 7402 / 844

On to step 8:
844 can be fit into 7402 8 times, resulting in a remainder of 650.
The number 8 becomes the next digit in our result. 
Result so far: 50758.0
Deduct 6752 from 7402 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 9:
The number 844 fits into 6500 7 times, leaving a remainder of 592.
Put 7 as the next digit of the answer. 
Result so far: 50758.7
If we subtract 5908 from 6500, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 10:
If we divide 5920 by 844, we get 7 and a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 50758.77
Deduct 5908 from 5920 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.

After the division, we end up with 50758.77 and a remainder of 0.012.
