Let's divide 81049310 by 309
We want to figure out the number of times 81049310 can be divided by 309.

Moving on to step 1:
8 divided by 309 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 309

Going ahead to step 2:
309 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 309

Moving on to step 3:
When dividing 810 by 309, we get 2 with a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 192 after subtracting 618 from 810.
Include the next digit (4) from the dividend after 192, then repeat: 1924 / 309

Let's proceed to step 4:
The number 309 fits into 1924 6 times, leaving a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 1854 from 1924 leaves us with 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 309

On to step 5:
709 divided by 309 is 2 with a remainder of 91.
Record the quotient 2 as the next digit in the result. 
Result so far: 262.0
Subtracting 618 from 709 leaves us with 91.
Bring next digit (3) of the dividend behind the 91 and repeat the process: 913 / 309

Let's proceed to step 6:
If we divide 913 by 309, we get 2 and a remainder of 295.
Record the quotient 2 as the next digit in the result. 
Result so far: 2622.0
Subtracting 618 from 913 leaves us with 295.
Grab the next digit (1) from the dividend, add it to 295, then carry on: 2951 / 309

Advancing to step 7:
When dividing 2951 by 309, we get 9 with a remainder of 170.
Record the quotient 9 as the next digit in the result. 
Result so far: 26229.0
The remainder is 170 after subtracting 2781 from 2951.
Fetch the next digit (0) from the dividend, attach it to 170 and continue: 1700 / 309

Moving on to step 8:
309 goes into 1700 5 times with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 262295.0
Subtracting 1545 from 1700 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 9:
309 can be fit into 1550 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 262295.5
Subtract 1545 from 1550 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
50 divided by 309 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 262295.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
If we divide 500 by 309, we get 1 and a remainder of 191.
The number 1 becomes the next digit in our result. 
Result so far: 262295.501
Subtracting 309 from 500 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 12:
309 can be fit into 1910 6 times, resulting in a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 262295.5016
Deduct 1854 from 1910 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
The number 309 fits into 560 1 times, leaving a remainder of 251.
The number 1 becomes the next digit in our result. 
Result so far: 262295.50161
Subtracting 309 from 560 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 14:
The number 309 fits into 2510 8 times, leaving a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 262295.501618
If we take 2472 away from 2510, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 15:
When dividing 380 by 309, we get 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 262295.5016181
Deduct 309 from 380 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 16:
309 goes into 710 2 times with a remainder of 92.
The next digit of our result is 2. 
Result so far: 262295.50161812
Subtracting 618 from 710 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 262295.50161812 with a remainder of 9.2e-08.
