303646 ÷ 45 
We want to divide 303646 by 45.

Let's proceed to step 1:
The number 45 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 45

Let's proceed to step 2:
45 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 45

Advancing to step 3:
303 divided by 45 is 6 with a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 33 after subtracting 270 from 303.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 45

Going ahead to step 4:
When dividing 336 by 45, we get 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 67.0
The remainder is 21 after subtracting 315 from 336.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 45

Let's proceed to step 5:
214 divided by 45 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 674.0
Subtracting 180 from 214 leaves us with 34.
Append the next digit (6) from the dividend to 34 and continue with: 346 / 45

On to step 6:
45 can be fit into 346 7 times, resulting in a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 6747.0
Subtract 315 from 346 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
45 can be fit into 310 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 6747.6
Deduct 270 from 310 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 45 fits into 400 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 6747.68
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
45 can be fit into 400 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 6747.688
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 6747.688 with a balance of 0.004.
