89947748 ÷ 309 
Our goal is to divide 89947748 by 309.

Step 1:
309 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 309

Moving on to step 2:
If we divide 89 by 309, we get 0 and a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Fetch the next digit (9) from the dividend, attach it to 89 and continue: 899 / 309

Going ahead to step 3:
When dividing 899 by 309, we get 2 with a remainder of 281.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 618 from 899, we get 281.
Bring next digit (4) of the dividend behind the 281 and repeat the process: 2814 / 309

Advancing to step 4:
309 goes into 2814 9 times with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 2781 from 2814 and we're left with 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 309

Going ahead to step 5:
309 can be fit into 337 1 times, resulting in a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 291.0
The remainder is 28 after subtracting 309 from 337.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 309

Going ahead to step 6:
287 divided by 309 is 0 with a remainder of 287.
The number 0 becomes the next digit in our result. 
Result so far: 2910.0
Subtracting 0 from 287 leaves us with 287.
Grab the next digit (4) from the dividend, add it to 287, then carry on: 2874 / 309

Moving on to step 7:
The number 309 fits into 2874 9 times, leaving a remainder of 93.
The next digit of our result is 9. 
Result so far: 29109.0
Deduct 2781 from 2874 and we're left with 93.
Fetch the next digit (8) from the dividend, attach it to 93 and continue: 938 / 309

Step 8:
309 goes into 938 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 291093.0
If we subtract 927 from 938, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
309 can be fit into 110 0 times, resulting in a remainder of 110.
The next digit of our result is 0. 
Result so far: 291093.0
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
If we divide 1100 by 309, we get 3 and a remainder of 173.
Write down 3 as next digit of the result. 
Result so far: 291093.03
Deduct 927 from 1100 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 11:
When dividing 1730 by 309, we get 5 with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 291093.035
If we subtract 1545 from 1730, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 12:
1850 divided by 309 is 5 with a remainder of 305.
The next digit of our result is 5. 
Result so far: 291093.0355
Deduct 1545 from 1850 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

The quotient of the division is 291093.0355, and the remainder is 0.00305.
