195149 divided by 45 
We want to divide 195149 by 45.

Advancing to step 1:
The number 45 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 45

Advancing to step 2:
The number 45 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 45

Step 3:
The number 45 fits into 195 4 times, leaving a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 180 from 195, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 45

Step 4:
151 divided by 45 is 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 135 from 151 and we're left with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 45

Going ahead to step 5:
If we divide 164 by 45, we get 3 and a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
Subtracting 135 from 164 leaves us with 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 45

Step 6:
The number 45 fits into 299 6 times, leaving a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 4336.0
If we take 270 away from 299, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
290 divided by 45 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 4336.6
Deduct 270 from 290 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 4336.64
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 45 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4336.644
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 4336.644, with a leftover of 0.002.
