We look at the division of 154413 by 45 
Our goal is to divide 154413 by 45.

Step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 45

Let's proceed to step 2:
15 divided by 45 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 45

Step 3:
The number 45 fits into 154 3 times, leaving a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 19 after subtracting 135 from 154.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 45

Step 4:
If we divide 194 by 45, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 34.0
The remainder is 14 after subtracting 180 from 194.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 45

On to step 5:
If we divide 141 by 45, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 343.0
Deduct 135 from 141 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 45

Let's proceed to step 6:
45 goes into 63 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 3431.0
If we subtract 45 from 63, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
45 can be fit into 180 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 3431.4
Subtract 180 from 180 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
45 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3431.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3431.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3431.4 with a remaining 0.0.
