We look at the division of 445086 by 20 
We want to figure out the number of times 445086 can be divided by 20.

Going ahead to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 20

Going ahead to step 2:
20 can be fit into 44 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we take 40 away from 44, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 20

Advancing to step 3:
When dividing 45 by 20, we get 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 40 away from 45, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 20

Going ahead to step 4:
20 can be fit into 50 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 222.0
Deduct 40 from 50 and we're left with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 20

Let's proceed to step 5:
When dividing 108 by 20, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 2225.0
Subtracting 100 from 108 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 20

Moving on to step 6:
If we divide 86 by 20, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 22254.0
Deduct 80 from 86 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
20 goes into 60 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 22254.3
If we subtract 60 from 60, 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.

Step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22254.3
The remainder is 0 after subtracting 0 from 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 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22254.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 22254.3, with a leftover of 0.0.
