Let's divide 902386 by 80
Our goal is to divide 902386 by 80.

Going ahead to step 1:
80 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 80

Moving on to step 2:
80 goes into 90 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 90 leaves us with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 80

Advancing to step 3:
The number 80 fits into 102 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 80 from 102 and we're left with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 80

Let's proceed to step 4:
If we divide 223 by 80, we get 2 and a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtract 160 from 223 to get 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 80

Let's proceed to step 5:
When dividing 638 by 80, we get 7 with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 1127.0
If we take 560 away from 638, we end up with 78.
Append the next digit (6) from the dividend to 78 and continue with: 786 / 80

Going ahead to step 6:
80 can be fit into 786 9 times, resulting in a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 11279.0
If we subtract 720 from 786, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 7:
80 goes into 660 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 11279.8
Deduct 640 from 660 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 11279.82
If we take 160 away from 200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11279.825
If we take 400 away from 400, 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 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11279.825
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.

On to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11279.825
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.

The final result is 11279.825 with a remainder of 0.0.
