We divide 866620 by 45
Let's see how many times 45 fits into 866620.

Going ahead to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 45

Moving on to step 2:
When dividing 86 by 45, we get 1 with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 41 after subtracting 45 from 86.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 45

Let's proceed to step 3:
If we divide 416 by 45, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 405 from 416, we get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 45

Let's proceed to step 4:
The number 45 fits into 116 2 times, leaving a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Deduct 90 from 116 and we're left with 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 45

Moving on to step 5:
45 can be fit into 262 5 times, resulting in a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 1925.0
If we subtract 225 from 262, we get 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 45

On to step 6:
45 goes into 370 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 19258.0
If we take 360 away from 370, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
When dividing 100 by 45, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 19258.2
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 45 fits into 100 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 19258.22
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 19258.22 with a remaining 0.01.
