We're dividing 80239210 by 309 
Let's see how many times 309 fits into 80239210.

On to step 1:
309 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
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 / 309

Going ahead to step 2:
If we divide 80 by 309, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 309

Advancing to step 3:
The number 309 fits into 802 2 times, leaving a remainder of 184.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 618 from 802 and we're left with 184.
Include the next digit (3) from the dividend after 184, then repeat: 1843 / 309

Step 4:
When dividing 1843 by 309, we get 5 with a remainder of 298.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 1545 from 1843 to get 298.
Grab the next digit (9) from the dividend, add it to 298, then carry on: 2989 / 309

Moving on to step 5:
If we divide 2989 by 309, we get 9 and a remainder of 208.
Write down 9 as next digit of the result. 
Result so far: 259.0
If we subtract 2781 from 2989, we get 208.
Grab the next digit (2) from the dividend, add it to 208, then carry on: 2082 / 309

Step 6:
If we divide 2082 by 309, we get 6 and a remainder of 228.
Record the quotient 6 as the next digit in the result. 
Result so far: 2596.0
Subtracting 1854 from 2082 leaves us with 228.
Take the next digit (1) from the dividend and append it to 228, then repeat: 2281 / 309

Step 7:
The number 309 fits into 2281 7 times, leaving a remainder of 118.
Put 7 as the next digit of the answer. 
Result so far: 25967.0
Subtract 2163 from 2281 to get 118.
Fetch the next digit (0) from the dividend, attach it to 118 and continue: 1180 / 309

Moving on to step 8:
The number 309 fits into 1180 3 times, leaving a remainder of 253.
Record the quotient 3 as the next digit in the result. 
Result so far: 259673.0
Subtract 927 from 1180 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 9:
If we divide 2530 by 309, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 259673.8
Subtract 2472 from 2530 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
The number 309 fits into 580 1 times, leaving a remainder of 271.
The next digit of our result is 1. 
Result so far: 259673.81
If we subtract 309 from 580, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 11:
If we divide 2710 by 309, we get 8 and a remainder of 238.
The number 8 becomes the next digit in our result. 
Result so far: 259673.818
Subtracting 2472 from 2710 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 12:
309 can be fit into 2380 7 times, resulting in a remainder of 217.
The number 7 becomes the next digit in our result. 
Result so far: 259673.8187
The remainder is 217 after subtracting 2163 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 13:
309 can be fit into 2170 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 259673.81877
If we subtract 2163 from 2170, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 259673.81877, and the remainder is 7e-06.
