39691758 ÷ 303 
Our goal is to divide 39691758 by 303.

Advancing to step 1:
If we divide 3 by 303, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 303

Let's proceed to step 2:
303 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 303

Let's proceed to step 3:
303 can be fit into 396 1 times, resulting in a remainder of 93.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 303 from 396 and we're left with 93.
Take the next digit (9) from the dividend and append it to 93, then repeat: 939 / 303

Step 4:
When dividing 939 by 303, we get 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 909 away from 939, we end up with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 303

Going ahead to step 5:
The number 303 fits into 301 0 times, leaving a remainder of 301.
The next digit of our result is 0. 
Result so far: 130.0
Subtracting 0 from 301 leaves us with 301.
Include the next digit (7) from the dividend after 301, then repeat: 3017 / 303

On to step 6:
303 goes into 3017 9 times with a remainder of 290.
Use 9 as the next digit of our solution. 
Result so far: 1309.0
If we take 2727 away from 3017, we end up with 290.
Grab the next digit (5) from the dividend, add it to 290, then carry on: 2905 / 303

On to step 7:
If we divide 2905 by 303, we get 9 and a remainder of 178.
Put 9 as the next digit of the answer. 
Result so far: 13099.0
If we subtract 2727 from 2905, we get 178.
Take the next digit (8) from the dividend and append it to 178, then repeat: 1788 / 303

Let's proceed to step 8:
303 can be fit into 1788 5 times, resulting in a remainder of 273.
The next digit of our result is 5. 
Result so far: 130995.0
Subtracting 1515 from 1788 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 9:
303 can be fit into 2730 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 130995.9
If we take 2727 away from 2730, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
303 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 130995.9
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
The number 303 fits into 300 0 times, leaving a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 130995.9
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 130995.9, with a leftover of 0.03.
