Let's divide 30302 by 39
We want to figure out the number of times 30302 can be divided by 39.

Going ahead to step 1:
If we divide 3 by 39, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 39

Moving on to step 2:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 39

On to step 3:
39 goes into 303 7 times with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 273 from 303 leaves us with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 39

Step 4:
If we divide 300 by 39, we get 7 and a remainder of 27.
The next digit of our result is 7. 
Result so far: 77.0
The remainder is 27 after subtracting 273 from 300.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 39

Advancing to step 5:
The number 39 fits into 272 6 times, leaving a remainder of 38.
The next digit of our result is 6. 
Result so far: 776.0
Deduct 234 from 272 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 6:
When dividing 380 by 39, we get 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 776.9
The remainder is 29 after subtracting 351 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
The number 39 fits into 290 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 776.97
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
When dividing 170 by 39, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 776.974
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
39 goes into 140 3 times with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 776.9743
If we subtract 117 from 140, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
230 divided by 39 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 776.97435
If we subtract 195 from 230, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
39 can be fit into 350 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 776.974358
If we take 312 away from 350, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 776.9743589
Subtract 351 from 380 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
290 divided by 39 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 776.97435897
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 776.97435897 with a remaining 1.7e-08.
