We look at the division of 412156 by 20 
We're looking to find how many times 20 goes into 412156.

Let's proceed to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 20

Moving on to step 2:
41 divided by 20 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 40 away from 41, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 20

Step 3:
12 divided by 20 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 20

Going ahead to step 4:
When dividing 121 by 20, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 206.0
If we take 120 away from 121, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 20

Step 5:
20 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 2060.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 20

Let's proceed to step 6:
When dividing 156 by 20, we get 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 20607.0
Deduct 140 from 156 and we're left 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.

Step 7:
When dividing 160 by 20, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 20607.8
Deduct 160 from 160 and we're left 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.

Advancing to step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20607.8
Deduct 0 from 0 and we're left 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.

Let's proceed to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 20607.8
If we subtract 0 from 0, 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.

Our division results in 20607.8 with a remaining 0.0.
