820172 divided by 1 
Our goal is to divide 820172 by 1.

Let's proceed to step 1:
8 divided by 1 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Let's proceed to step 2:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
If we subtract 2 from 2, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Going ahead to step 3:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
If we take 0 away from 0, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Let's proceed to step 4:
1 can be fit into 1 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 8201.0
Subtract 1 from 1 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

On to step 5:
7 divided by 1 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 82017.0
If we take 7 away from 7, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

On to step 6:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 820172.0
Subtract 2 from 2 to 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.

Let's proceed to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 820172.0
If we take 0 away from 0, 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.

Step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 820172.0
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 820172.0 with a remaining 0.0.
