We're dividing 148419 by 45 
We want to divide 148419 by 45.

On to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 45

Let's proceed 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
If we subtract 0 from 14, we get 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 45

Advancing to step 3:
The number 45 fits into 148 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 135 from 148 leaves us with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 45

Advancing to step 4:
134 divided by 45 is 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 32.0
The remainder is 44 after subtracting 90 from 134.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 45

Going ahead to step 5:
45 can be fit into 441 9 times, resulting in a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 329.0
Subtract 405 from 441 to get 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 45

Let's proceed to step 6:
If we divide 369 by 45, we get 8 and a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 3298.0
Subtract 360 from 369 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 45 fits into 90 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 3298.2
If we subtract 90 from 90, we 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:
If we divide 0 by 45, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3298.2
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.

Moving on to step 9:
The number 45 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3298.2
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.

The final outcome is 3298.2, with a leftover of 0.0.
