We look at the division of 149278 by 45 
We want to divide 149278 by 45.

On to step 1:
If we divide 1 by 45, we get 0 and 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.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 45

Advancing to step 2:
If we divide 14 by 45, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 45

Going ahead to step 3:
45 can be fit into 149 3 times, resulting in a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 135 from 149 and we're left with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 45

On to step 4:
The number 45 fits into 142 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 135 from 142 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 45

On to step 5:
The number 45 fits into 77 1 times, leaving a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 331.0
The remainder is 32 after subtracting 45 from 77.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 45

Let's proceed to step 6:
When dividing 328 by 45, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3317.0
The remainder is 13 after subtracting 315 from 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
When dividing 130 by 45, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 3317.2
If we take 90 away from 130, 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.

Moving on to step 8:
45 goes into 400 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 3317.28
Subtracting 360 from 400 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 9:
45 goes into 400 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 3317.288
The remainder is 40 after subtracting 360 from 400.
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 3317.288, and the remainder is 0.004.
