80348423 divided by 30 
We want to divide 80348423 by 30.

Let's proceed to step 1:
When dividing 8 by 30, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 30

Advancing to step 2:
If we divide 80 by 30, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 60 away from 80, we end up with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 30

Moving on to step 3:
The number 30 fits into 203 6 times, leaving a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 180 away from 203, we end up with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 30

On to step 4:
If we divide 234 by 30, we get 7 and a remainder of 24.
The next digit of our result is 7. 
Result so far: 267.0
Subtracting 210 from 234 leaves us with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 30

Advancing to step 5:
30 goes into 248 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 2678.0
Subtract 240 from 248 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 30

Going ahead to step 6:
30 can be fit into 84 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 26782.0
Subtracting 60 from 84 leaves us with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 30

Step 7:
30 can be fit into 242 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 267828.0
Deduct 240 from 242 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 30

Going ahead to step 8:
23 divided by 30 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 2678280.0
If we subtract 0 from 23, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
When dividing 230 by 30, we get 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 2678280.7
Deduct 210 from 230 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 2678280.76
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 2678280.766
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 2678280.766, and the remainder is 0.002.
