Let's divide 39679824 by 491
Our goal is to divide 39679824 by 491.

Step 1:
The number 491 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 491

Step 2:
39 divided by 491 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 491

Moving on to step 3:
The number 491 fits into 396 0 times, leaving a remainder of 396.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 396, we end up with 396.
Bring next digit (7) of the dividend behind the 396 and repeat the process: 3967 / 491

Step 4:
The number 491 fits into 3967 8 times, leaving a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 3928 from 3967 to get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 491

Let's proceed to step 5:
The number 491 fits into 399 0 times, leaving a remainder of 399.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we subtract 0 from 399, we get 399.
Bring next digit (8) of the dividend behind the 399 and repeat the process: 3998 / 491

Moving on to step 6:
If we divide 3998 by 491, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 808.0
If we take 3928 away from 3998, we end up with 70.
Fetch the next digit (2) from the dividend, attach it to 70 and continue: 702 / 491

Going ahead to step 7:
When dividing 702 by 491, we get 1 with a remainder of 211.
Record the quotient 1 as the next digit in the result. 
Result so far: 8081.0
If we subtract 491 from 702, we get 211.
Include the next digit (4) from the dividend after 211, then repeat: 2114 / 491

Moving on to step 8:
491 goes into 2114 4 times with a remainder of 150.
The number 4 becomes the next digit in our result. 
Result so far: 80814.0
The remainder is 150 after subtracting 1964 from 2114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 9:
1500 divided by 491 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 80814.3
The remainder is 27 after subtracting 1473 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
The number 491 fits into 270 0 times, leaving a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 80814.3
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 11:
The number 491 fits into 2700 5 times, leaving a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 80814.305
If we take 2455 away from 2700, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 12:
2450 divided by 491 is 4 with a remainder of 486.
Write down 4 as next digit of the result. 
Result so far: 80814.3054
Deduct 1964 from 2450 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 13:
4860 divided by 491 is 9 with a remainder of 441.
Write down 9 as next digit of the result. 
Result so far: 80814.30549
If we take 4419 away from 4860, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Going ahead to step 14:
491 can be fit into 4410 8 times, resulting in a remainder of 482.
Write down 8 as next digit of the result. 
Result so far: 80814.305498
Subtract 3928 from 4410 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 15:
491 goes into 4820 9 times with a remainder of 401.
Record the quotient 9 as the next digit in the result. 
Result so far: 80814.3054989
Subtracting 4419 from 4820 leaves us with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Step 16:
The number 491 fits into 4010 8 times, leaving a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 80814.30549898
Subtract 3928 from 4010 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

In conclusion, the division gives 80814.30549898 with a balance of 8.2e-08.
