63807821 ÷ 491 
We want to divide 63807821 by 491.

Moving on to step 1:
When dividing 6 by 491, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 491

Let's proceed to step 2:
491 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 491

Advancing to step 3:
The number 491 fits into 638 1 times, leaving a remainder of 147.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 491 from 638, we get 147.
Take the next digit (0) from the dividend and append it to 147, then repeat: 1470 / 491

Let's proceed to step 4:
When dividing 1470 by 491, we get 2 with a remainder of 488.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 982 from 1470 to get 488.
Take the next digit (7) from the dividend and append it to 488, then repeat: 4887 / 491

Step 5:
If we divide 4887 by 491, we get 9 and a remainder of 468.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
The remainder is 468 after subtracting 4419 from 4887.
Grab the next digit (8) from the dividend, add it to 468, then carry on: 4688 / 491

Advancing to step 6:
The number 491 fits into 4688 9 times, leaving a remainder of 269.
Put 9 as the next digit of the answer. 
Result so far: 1299.0
Subtracting 4419 from 4688 leaves us with 269.
Append the next digit (2) from the dividend to 269 and continue with: 2692 / 491

Let's proceed to step 7:
If we divide 2692 by 491, we get 5 and a remainder of 237.
Put 5 as the next digit of the answer. 
Result so far: 12995.0
If we subtract 2455 from 2692, we get 237.
Bring next digit (1) of the dividend behind the 237 and repeat the process: 2371 / 491

Going ahead to step 8:
If we divide 2371 by 491, we get 4 and a remainder of 407.
Write down 4 as next digit of the result. 
Result so far: 129954.0
If we take 1964 away from 2371, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 9:
4070 divided by 491 is 8 with a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 129954.8
Subtract 3928 from 4070 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 10:
The number 491 fits into 1420 2 times, leaving a remainder of 438.
Record the quotient 2 as the next digit in the result. 
Result so far: 129954.82
If we take 982 away from 1420, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 11:
491 goes into 4380 8 times with a remainder of 452.
Write down 8 as next digit of the result. 
Result so far: 129954.828
Deduct 3928 from 4380 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 12:
4520 divided by 491 is 9 with a remainder of 101.
Record the quotient 9 as the next digit in the result. 
Result so far: 129954.8289
The remainder is 101 after subtracting 4419 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 13:
491 can be fit into 1010 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 129954.82892
The remainder is 28 after subtracting 982 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
If we divide 280 by 491, we get 0 and a remainder of 280.
The next digit of our result is 0. 
Result so far: 129954.82892
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 15:
491 can be fit into 2800 5 times, resulting in a remainder of 345.
The next digit of our result is 5. 
Result so far: 129954.8289205
If we take 2455 away from 2800, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Going ahead to step 16:
491 can be fit into 3450 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 129954.82892057
The remainder is 13 after subtracting 3437 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 129954.82892057 with a balance of 1.3e-08.
