Let's divide 141312 by 45
We want to figure out the number of times 141312 can be divided by 45.

Moving on to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 45

Advancing to step 2:
45 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 45

Step 3:
45 goes into 141 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 6 after subtracting 135 from 141.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 45

Moving on to step 4:
45 can be fit into 63 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 45 from 63 to get 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 45

Let's proceed to step 5:
181 divided by 45 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 314.0
Deduct 180 from 181 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 45

Going ahead to step 6:
12 divided by 45 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 3140.0
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.

Going ahead to step 7:
The number 45 fits into 120 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 3140.2
Subtracting 90 from 120 leaves us 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.

Let's proceed to step 8:
300 divided by 45 is 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 3140.26
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
45 goes into 300 6 times with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 3140.266
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 3140.266, with a leftover of 0.003.
