Let's divide 210185 by 20
We want to figure out the number of times 210185 can be divided by 20.

Step 1:
If we divide 2 by 20, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 20

Moving on to step 2:
20 can be fit into 21 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 20 from 21 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 20

Moving on to step 3:
The number 20 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 20

Advancing to step 4:
20 can be fit into 101 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtract 100 from 101 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 20

Advancing to step 5:
The number 20 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 1050.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 20

Step 6:
The number 20 fits into 185 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 10509.0
Subtracting 180 from 185 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 20, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 10509.2
Deduct 40 from 50 and we're left 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.

Going ahead to step 8:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10509.25
If we take 100 away from 100, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10509.25
Subtracting 0 from 0 leaves us with 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 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10509.25
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.

Our division results in 10509.25 with a remaining 0.0.
