We look at the division of 803357 by 166 
Our goal is to divide 803357 by 166.

Going ahead to step 1:
8 divided by 166 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 166

Let's proceed to step 2:
When dividing 80 by 166, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 166

On to step 3:
If we divide 803 by 166, we get 4 and a remainder of 139.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 664 from 803, we get 139.
Append the next digit (3) from the dividend to 139 and continue with: 1393 / 166

Let's proceed to step 4:
166 can be fit into 1393 8 times, resulting in a remainder of 65.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 1328 from 1393 leaves us with 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 166

Going ahead to step 5:
If we divide 655 by 166, we get 3 and a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 483.0
If we subtract 498 from 655, we get 157.
Fetch the next digit (7) from the dividend, attach it to 157 and continue: 1577 / 166

Moving on to step 6:
166 can be fit into 1577 9 times, resulting in a remainder of 83.
The next digit of our result is 9. 
Result so far: 4839.0
Deduct 1494 from 1577 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 7:
830 divided by 166 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4839.5
If we subtract 830 from 830, 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 8:
When dividing 0 by 166, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4839.5
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.

Going ahead to step 9:
If we divide 0 by 166, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4839.5
Subtracting 0 from 0 leaves us 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 outcome is 4839.5, with a leftover of 0.0.
