We're dividing 87223231 by 306 
We're looking to find how many times 306 goes into 87223231.

Let's proceed to step 1:
If we divide 8 by 306, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 306

Going ahead to step 2:
The number 306 fits into 87 0 times, leaving a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Fetch the next digit (2) from the dividend, attach it to 87 and continue: 872 / 306

On to step 3:
306 can be fit into 872 2 times, resulting in a remainder of 260.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 612 from 872 leaves us with 260.
Take the next digit (2) from the dividend and append it to 260, then repeat: 2602 / 306

Moving on to step 4:
306 goes into 2602 8 times with a remainder of 154.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 2448 away from 2602, we end up with 154.
Include the next digit (3) from the dividend after 154, then repeat: 1543 / 306

Step 5:
1543 divided by 306 is 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 285.0
If we subtract 1530 from 1543, we get 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 306

On to step 6:
306 can be fit into 132 0 times, resulting in a remainder of 132.
The number 0 becomes the next digit in our result. 
Result so far: 2850.0
Subtracting 0 from 132 leaves us with 132.
Bring next digit (3) of the dividend behind the 132 and repeat the process: 1323 / 306

Step 7:
The number 306 fits into 1323 4 times, leaving a remainder of 99.
Use 4 as the next digit of our solution. 
Result so far: 28504.0
The remainder is 99 after subtracting 1224 from 1323.
Include the next digit (1) from the dividend after 99, then repeat: 991 / 306

On to step 8:
If we divide 991 by 306, we get 3 and a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 285043.0
Subtracting 918 from 991 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
730 divided by 306 is 2 with a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 285043.2
If we subtract 612 from 730, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 10:
1180 divided by 306 is 3 with a remainder of 262.
Write down 3 as next digit of the result. 
Result so far: 285043.23
Subtracting 918 from 1180 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 11:
The number 306 fits into 2620 8 times, leaving a remainder of 172.
Put 8 as the next digit of the answer. 
Result so far: 285043.238
If we subtract 2448 from 2620, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 12:
1720 divided by 306 is 5 with a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 285043.2385
Subtract 1530 from 1720 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 13:
When dividing 1900 by 306, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 285043.23856
Subtract 1836 from 1900 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
The number 306 fits into 640 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 285043.238562
Subtract 612 from 640 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 15:
306 goes into 280 0 times with a remainder of 280.
The next digit of our result is 0. 
Result so far: 285043.238562
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
306 goes into 2800 9 times with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 285043.23856209
If we subtract 2754 from 2800, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 285043.23856209 with a remaining 4.6e-08.
