We're dividing 80422130 by 302 
We want to figure out the number of times 80422130 can be divided by 302.

Moving on to step 1:
302 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 302

Let's proceed to step 2:
302 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 302

Going ahead to step 3:
302 goes into 804 2 times with a remainder of 200.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 604 from 804 leaves us with 200.
Bring next digit (2) of the dividend behind the 200 and repeat the process: 2002 / 302

Going ahead to step 4:
If we divide 2002 by 302, we get 6 and a remainder of 190.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 1812 from 2002 and we're left with 190.
Take the next digit (2) from the dividend and append it to 190, then repeat: 1902 / 302

On to step 5:
1902 divided by 302 is 6 with a remainder of 90.
Record the quotient 6 as the next digit in the result. 
Result so far: 266.0
Deduct 1812 from 1902 and we're left with 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 302

Moving on to step 6:
If we divide 901 by 302, we get 2 and a remainder of 297.
Use 2 as the next digit of our solution. 
Result so far: 2662.0
Subtracting 604 from 901 leaves us with 297.
Take the next digit (3) from the dividend and append it to 297, then repeat: 2973 / 302

Advancing to step 7:
If we divide 2973 by 302, we get 9 and a remainder of 255.
Write down 9 as next digit of the result. 
Result so far: 26629.0
If we subtract 2718 from 2973, we get 255.
Include the next digit (0) from the dividend after 255, then repeat: 2550 / 302

Step 8:
When dividing 2550 by 302, we get 8 with a remainder of 134.
The next digit of our result is 8. 
Result so far: 266298.0
If we take 2416 away from 2550, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 9:
302 goes into 1340 4 times with a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 266298.4
Deduct 1208 from 1340 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 10:
302 can be fit into 1320 4 times, resulting in a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 266298.44
If we subtract 1208 from 1320, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The quotient of the division is 266298.44, and the remainder is 0.112.
