661275 divided by 45 
We want to figure out the number of times 661275 can be divided by 45.

Step 1:
45 can be fit into 6 0 times, resulting in 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.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 45

Going ahead to step 2:
45 can be fit into 66 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 66, we get 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 45

Step 3:
The number 45 fits into 211 4 times, leaving a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 180 from 211 to get 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 45

Going ahead to step 4:
The number 45 fits into 312 6 times, leaving a remainder of 42.
The next digit of our result is 6. 
Result so far: 146.0
Deduct 270 from 312 and we're left with 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 45

On to step 5:
45 can be fit into 427 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 1469.0
Deduct 405 from 427 and we're left with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 45

Step 6:
The number 45 fits into 225 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 14695.0
If we subtract 225 from 225, 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.

On to step 7:
45 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 14695.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14695.0
Subtract 0 from 0 to 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.

Our division results in 14695.0 with a remaining 0.0.
