206151 divided by 20 
Let's see how many times 20 fits into 206151.

Advancing to step 1:
When dividing 2 by 20, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 20

On to step 2:
20 can be fit into 20 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 20 from 20 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 20

Going ahead to step 3:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 20

On to step 4:
20 goes into 61 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Subtracting 60 from 61 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 20

Moving on to step 5:
20 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 1030.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 20

Let's proceed to step 6:
If we divide 151 by 20, we get 7 and a remainder of 11.
The next digit of our result is 7. 
Result so far: 10307.0
If we take 140 away from 151, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
When dividing 110 by 20, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10307.5
Subtract 100 from 110 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.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10307.55
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.

Our division results in 10307.55 with a remaining 0.0.
