666196 divided by 45 
Let's see how many times 45 fits into 666196.

Going ahead to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 45

On to step 2:
45 can be fit into 66 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 45 from 66 leaves us with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 45

Going ahead to step 3:
45 can be fit into 216 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 180 from 216 leaves us with 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 45

Going ahead to step 4:
When dividing 361 by 45, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 148.0
If we subtract 360 from 361, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 45

Moving on to step 5:
45 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 1480.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 45

Let's proceed to step 6:
196 divided by 45 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 14804.0
If we take 180 away from 196, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
When dividing 160 by 45, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 14804.3
The remainder is 25 after subtracting 135 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
45 can be fit into 250 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 14804.35
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
When dividing 250 by 45, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 14804.355
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 14804.355 and a remainder of 0.0025.
