Let's divide 3612 by 45
We want to figure out the number of times 3612 can be divided by 45.

Step 1:
When dividing 3 by 45, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 45

Moving on to step 2:
When dividing 36 by 45, we get 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 45

Advancing to step 3:
45 can be fit into 361 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 360 from 361 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 45

Advancing to step 4:
45 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 12 after subtracting 0 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 5:
45 can be fit into 120 2 times, resulting in a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 80.2
If we take 90 away from 120, we end up 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.

Step 6:
When dividing 300 by 45, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 80.26
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.

Advancing to step 7:
If we divide 300 by 45, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 80.266
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.

After the division, we end up with 80.266 and a remainder of 0.003.
