169320 ÷ 45 
Let's see how many times 45 fits into 169320.

Step 1:
The number 45 fits into 1 0 times, leaving 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 (6) of the dividend behind the 1 and repeat the process: 16 / 45

Moving on to step 2:
16 divided by 45 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 45

Step 3:
45 can be fit into 169 3 times, resulting in a remainder of 34.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 135 from 169, we get 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 45

Step 4:
343 divided by 45 is 7 with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 37.0
The remainder is 28 after subtracting 315 from 343.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 45

Advancing to step 5:
When dividing 282 by 45, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 376.0
Deduct 270 from 282 and we're left with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 45

Let's proceed to step 6:
120 divided by 45 is 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 3762.0
Deduct 90 from 120 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 7:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 3762.6
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 3762.66
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 3762.66, and the remainder is 0.03.
