Let's divide 666881 by 45
We want to figure out the number of times 666881 can be divided by 45.

On to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 45

Let's proceed to step 2:
66 divided by 45 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 45 from 66 and we're left with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 45

Moving on to step 3:
When dividing 216 by 45, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 180 from 216, we get 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 45

Going ahead to step 4:
45 can be fit into 368 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 148.0
If we take 360 away from 368, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 45

Step 5:
When dividing 88 by 45, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1481.0
Subtract 45 from 88 to get 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 45

Step 6:
When dividing 431 by 45, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 14819.0
The remainder is 26 after subtracting 405 from 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
If we divide 260 by 45, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 14819.5
Subtracting 225 from 260 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:
350 divided by 45 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 14819.57
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.

On to step 9:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 14819.577
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.

Our division results in 14819.577 with a remaining 0.0035.
