353270 ÷ 45 
We want to figure out the number of times 353270 can be divided by 45.

Step 1:
45 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 45

Going ahead to step 2:
35 divided by 45 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 45

Moving on to step 3:
If we divide 353 by 45, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 315 from 353 and we're left with 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 45

Moving on to step 4:
If we divide 382 by 45, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtracting 360 from 382 leaves us with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 45

Let's proceed to step 5:
45 can be fit into 227 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 785.0
If we take 225 away from 227, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 45

Moving on to step 6:
20 divided by 45 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7850.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
If we divide 200 by 45, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 7850.4
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 45 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 7850.44
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 7850.44, with a leftover of 0.02.
