We divide 661773 by 45
We're looking to find how many times 45 goes into 661773.

On to step 1:
6 divided by 45 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 45

Step 2:
When dividing 66 by 45, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 45 from 66 and we're left with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 45

Advancing to step 3:
45 goes into 211 4 times with a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 180 from 211, we get 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 45

Advancing to step 4:
45 goes into 317 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 147.0
If we take 315 away from 317, we end up with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 45

Advancing to step 5:
When dividing 27 by 45, we get 0 with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 1470.0
If we subtract 0 from 27, we get 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 45

Let's proceed to step 6:
The number 45 fits into 273 6 times, leaving a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 14706.0
If we subtract 270 from 273, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 45 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 14706.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 14706.06
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 14706.066
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 14706.066 with a remainder of 0.003.
