Let's divide 80210 by 8
Our goal is to divide 80210 by 8.

Step 1:
8 can be fit into 8 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 8 away from 8, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 8

Step 2:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 8

Moving on to step 3:
When dividing 2 by 8, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 8

Step 4:
When dividing 21 by 8, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 1002.0
If we subtract 16 from 21, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 8

Going ahead to step 5:
50 divided by 8 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 10026.0
Deduct 48 from 50 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 6:
8 goes into 20 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10026.2
If we take 16 away from 20, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 8, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 10026.25
The remainder is 0 after subtracting 40 from 40.
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 8:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10026.25
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.

Step 9:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10026.25
Subtract 0 from 0 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.

The final outcome is 10026.25, with a leftover of 0.0.
