151520 ÷ 45 
Our goal is to divide 151520 by 45.

Going ahead to step 1:
1 divided by 45 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 45

Advancing to step 2:
When dividing 15 by 45, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 45

Going ahead to step 3:
When dividing 151 by 45, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 135 from 151 to get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 45

On to step 4:
45 goes into 165 3 times with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 135 from 165 to get 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 45

Advancing to step 5:
45 can be fit into 302 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 336.0
The remainder is 32 after subtracting 270 from 302.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 45

On to step 6:
45 goes into 320 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 3367.0
If we subtract 315 from 320, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 45, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 3367.1
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
45 can be fit into 50 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 3367.11
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 3367.11 and a remainder of 0.005.
