154255 divided by 45 
Let's see how many times 45 fits into 154255.

Step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 45

Moving on to step 2:
45 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 45

Moving on to step 3:
If we divide 154 by 45, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 135 from 154 and we're left with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 45

Going ahead to step 4:
45 goes into 192 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 180 from 192, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 45

Moving on to step 5:
45 can be fit into 125 2 times, resulting in a remainder of 35.
The next digit of our result is 2. 
Result so far: 342.0
Subtract 90 from 125 to get 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 45

Step 6:
If we divide 355 by 45, we get 7 and a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 3427.0
Subtracting 315 from 355 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
45 goes into 400 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 3427.8
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
45 can be fit into 400 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 3427.88
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 3427.88, and the remainder is 0.04.
