153309 divided by 45 
We want to divide 153309 by 45.

Going ahead to step 1:
45 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 45

Going ahead to step 2:
If we divide 15 by 45, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 45

On to step 3:
45 goes into 153 3 times with a remainder of 18.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 18 after subtracting 135 from 153.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 45

Step 4:
183 divided by 45 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we take 180 away from 183, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 45

Advancing to step 5:
If we divide 30 by 45, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 340.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 45

On to step 6:
45 can be fit into 309 6 times, resulting in a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 3406.0
If we subtract 270 from 309, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
390 divided by 45 is 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 3406.8
If we subtract 360 from 390, 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.

Moving on to step 8:
300 divided by 45 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 3406.86
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 3406.866
Subtract 270 from 300 to 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.

In conclusion, the division gives 3406.866 with a balance of 0.003.
