We're dividing 30309209 by 45 
Our goal is to divide 30309209 by 45.

Let's proceed to step 1:
3 divided by 45 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 45

Going ahead to step 2:
30 divided by 45 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 45

On to step 3:
When dividing 303 by 45, we get 6 with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 270 from 303, we get 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 45

Going ahead to step 4:
45 can be fit into 330 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Deduct 315 from 330 and we're left with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 45

On to step 5:
If we divide 159 by 45, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 673.0
Subtract 135 from 159 to get 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 45

Moving on to step 6:
45 goes into 242 5 times with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 6735.0
If we subtract 225 from 242, we get 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 45

Moving on to step 7:
170 divided by 45 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 67353.0
Subtract 135 from 170 to get 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 45

Going ahead to step 8:
When dividing 359 by 45, we get 7 with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 673537.0
Deduct 315 from 359 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
When dividing 440 by 45, we get 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 673537.9
If we take 405 away from 440, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
When dividing 350 by 45, we get 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 673537.97
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
45 goes into 350 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 673537.977
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 673537.977 with a remaining 0.0035.
