We look at the division of 83394 by 80 
Let's see how many times 80 fits into 83394.

Step 1:
8 divided by 80 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 80

Going ahead to step 2:
83 divided by 80 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 80 from 83 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 80

Advancing to step 3:
The number 80 fits into 33 0 times, leaving a remainder of 33.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 33 after subtracting 0 from 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 80

Step 4:
80 can be fit into 339 4 times, resulting in a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we subtract 320 from 339, we get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 80

Step 5:
When dividing 194 by 80, we get 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 1042.0
Deduct 160 from 194 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 6:
80 can be fit into 340 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1042.4
Subtract 320 from 340 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1042.42
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1042.425
If we subtract 400 from 400, 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.

Advancing to step 9:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1042.425
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 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1042.425
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.

After the division, we end up with 1042.425 and a remainder of 0.0.
