We divide 63986381 by 497
We want to divide 63986381 by 497.

On to step 1:
497 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 497

Let's proceed to step 2:
When dividing 63 by 497, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 497

Moving on to step 3:
497 can be fit into 639 1 times, resulting in a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 497 from 639 leaves us with 142.
Take the next digit (8) from the dividend and append it to 142, then repeat: 1428 / 497

Going ahead to step 4:
497 can be fit into 1428 2 times, resulting in a remainder of 434.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 994 from 1428, we get 434.
Include the next digit (6) from the dividend after 434, then repeat: 4346 / 497

Going ahead to step 5:
497 goes into 4346 8 times with a remainder of 370.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Subtracting 3976 from 4346 leaves us with 370.
Take the next digit (3) from the dividend and append it to 370, then repeat: 3703 / 497

Step 6:
If we divide 3703 by 497, we get 7 and a remainder of 224.
Record the quotient 7 as the next digit in the result. 
Result so far: 1287.0
Subtracting 3479 from 3703 leaves us with 224.
Append the next digit (8) from the dividend to 224 and continue with: 2248 / 497

Moving on to step 7:
497 can be fit into 2248 4 times, resulting in a remainder of 260.
Use 4 as the next digit of our solution. 
Result so far: 12874.0
Subtracting 1988 from 2248 leaves us with 260.
Fetch the next digit (1) from the dividend, attach it to 260 and continue: 2601 / 497

On to step 8:
497 goes into 2601 5 times with a remainder of 116.
Record the quotient 5 as the next digit in the result. 
Result so far: 128745.0
Deduct 2485 from 2601 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 9:
497 goes into 1160 2 times with a remainder of 166.
The next digit of our result is 2. 
Result so far: 128745.2
Deduct 994 from 1160 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 10:
When dividing 1660 by 497, we get 3 with a remainder of 169.
Write down 3 as next digit of the result. 
Result so far: 128745.23
If we take 1491 away from 1660, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 11:
497 goes into 1690 3 times with a remainder of 199.
The next digit of our result is 3. 
Result so far: 128745.233
The remainder is 199 after subtracting 1491 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

After the division, we end up with 128745.233 and a remainder of 0.0199.
