Let's divide 309405 by 36
We want to figure out the number of times 309405 can be divided by 36.

On to step 1:
When dividing 3 by 36, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 36

Going ahead to step 2:
When dividing 30 by 36, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 36

Let's proceed to step 3:
If we divide 309 by 36, we get 8 and a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 288 from 309 to get 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 36

Going ahead to step 4:
36 can be fit into 214 5 times, resulting in a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 180 from 214 to get 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 36

Going ahead to step 5:
36 goes into 340 9 times with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 859.0
Subtracting 324 from 340 leaves us with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 36

On to step 6:
When dividing 165 by 36, we get 4 with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 8594.0
If we take 144 away from 165, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 36, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8594.5
If we subtract 180 from 210, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 36 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8594.58
Subtracting 288 from 300 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 36, we get 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 8594.583
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
120 divided by 36 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 8594.5833
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 8594.5833, and the remainder is 0.00012.
