661058 divided by 45 
We want to figure out the number of times 661058 can be divided by 45.

On to step 1:
6 divided by 45 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 45

On to step 2:
45 goes into 66 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 45 away from 66, we end up with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 45

Moving on 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
Subtracting 180 from 211 leaves us with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 45

Advancing to step 4:
If we divide 310 by 45, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 146.0
Subtract 270 from 310 to get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 45

Moving on to step 5:
The number 45 fits into 405 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 1469.0
The remainder is 0 after subtracting 405 from 405.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 45

Advancing to step 6:
The number 45 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 14690.0
The remainder is 8 after subtracting 0 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
The number 45 fits into 80 1 times, leaving a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 14690.1
Subtracting 45 from 80 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 14690.17
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
When dividing 350 by 45, we get 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 14690.177
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 14690.177 with a remainder of 0.0035.
