671771 divided by 45 
Let's see how many times 45 fits into 671771.

On to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 45

Moving on to step 2:
45 can be fit into 67 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 45 from 67 leaves us with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 45

Step 3:
45 goes into 221 4 times with a remainder of 41.
The next digit of our result is 4. 
Result so far: 14.0
If we take 180 away from 221, we end up with 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 45

Step 4:
417 divided by 45 is 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 149.0
Subtract 405 from 417 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 45

Going ahead to step 5:
When dividing 127 by 45, we get 2 with a remainder of 37.
The next digit of our result is 2. 
Result so far: 1492.0
Deduct 90 from 127 and we're left with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 45

Let's proceed to step 6:
If we divide 371 by 45, we get 8 and a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 14928.0
If we take 360 away from 371, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
45 goes into 110 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 14928.2
Deduct 90 from 110 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.

On to step 8:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 14928.24
Deduct 180 from 200 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.

Advancing to step 9:
When dividing 200 by 45, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 14928.244
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.

The quotient of the division is 14928.244, and the remainder is 0.002.
