491278 ÷ 39 
We want to figure out the number of times 491278 can be divided by 39.

Advancing to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 39

Going ahead to step 2:
39 can be fit into 49 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 39 from 49 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 39

Moving on to step 3:
39 can be fit into 101 2 times, resulting in a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 78 from 101, we get 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 39

Step 4:
If we divide 232 by 39, we get 5 and a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtract 195 from 232 to get 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 39

Let's proceed to step 5:
If we divide 377 by 39, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 1259.0
Subtract 351 from 377 to get 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 39

On to step 6:
39 goes into 268 6 times with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 12596.0
The remainder is 34 after subtracting 234 from 268.
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 7:
340 divided by 39 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 12596.8
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
When dividing 280 by 39, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 12596.87
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
70 divided by 39 is 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 12596.871
Subtracting 39 from 70 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 10:
The number 39 fits into 310 7 times, leaving a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 12596.8717
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
370 divided by 39 is 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 12596.87179
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
190 divided by 39 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 12596.871794
If we take 156 away from 190, we end up 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.

Advancing to step 13:
If we divide 340 by 39, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 12596.8717948
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
The number 39 fits into 280 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 12596.87179487
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 12596.87179487, with a leftover of 7e-09.
