640098 divided by 63 
Let's see how many times 63 fits into 640098.

Step 1:
The number 63 fits into 6 0 times, leaving 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 (4) from the dividend, attach it to 6 and continue: 64 / 63

On to step 2:
When dividing 64 by 63, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 63 away from 64, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 63

Advancing to step 3:
The number 63 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 10 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 63

Advancing to step 4:
63 can be fit into 100 1 times, resulting in a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
If we take 63 away from 100, we end up with 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 63

Going ahead to step 5:
If we divide 379 by 63, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 1016.0
Subtracting 378 from 379 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 63

Step 6:
63 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 10160.0
The remainder is 18 after subtracting 0 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
63 goes into 180 2 times with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 10160.2
If we subtract 126 from 180, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
If we divide 540 by 63, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 10160.28
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
360 divided by 63 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 10160.285
The remainder is 45 after subtracting 315 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
The number 63 fits into 450 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 10160.2857
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
When dividing 90 by 63, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 10160.28571
If we take 63 away from 90, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
63 can be fit into 270 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 10160.285714
The remainder is 18 after subtracting 252 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
When dividing 180 by 63, we get 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 10160.2857142
Subtracting 126 from 180 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 14:
63 goes into 540 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 10160.28571428
The remainder is 36 after subtracting 504 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 10160.28571428, with a leftover of 3.6e-08.
