Let's divide 63011771 by 643
We're looking to find how many times 643 goes into 63011771.

On to step 1:
The number 643 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 643

Moving on to step 2:
643 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 643

Let's proceed to step 3:
630 divided by 643 is 0 with a remainder of 630.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 630, we get 630.
Take the next digit (1) from the dividend and append it to 630, then repeat: 6301 / 643

Advancing to step 4:
If we divide 6301 by 643, we get 9 and a remainder of 514.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 5787 from 6301 and we're left with 514.
Append the next digit (1) from the dividend to 514 and continue with: 5141 / 643

Let's proceed to step 5:
When dividing 5141 by 643, we get 7 with a remainder of 640.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we subtract 4501 from 5141, we get 640.
Append the next digit (7) from the dividend to 640 and continue with: 6407 / 643

Advancing to step 6:
If we divide 6407 by 643, we get 9 and a remainder of 620.
Put 9 as the next digit of the answer. 
Result so far: 979.0
Deduct 5787 from 6407 and we're left with 620.
Append the next digit (7) from the dividend to 620 and continue with: 6207 / 643

Advancing to step 7:
643 goes into 6207 9 times with a remainder of 420.
Use 9 as the next digit of our solution. 
Result so far: 9799.0
Subtract 5787 from 6207 to get 420.
Append the next digit (1) from the dividend to 420 and continue with: 4201 / 643

Advancing to step 8:
4201 divided by 643 is 6 with a remainder of 343.
The number 6 becomes the next digit in our result. 
Result so far: 97996.0
Subtract 3858 from 4201 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 9:
The number 643 fits into 3430 5 times, leaving a remainder of 215.
Record the quotient 5 as the next digit in the result. 
Result so far: 97996.5
Subtracting 3215 from 3430 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 10:
If we divide 2150 by 643, we get 3 and a remainder of 221.
Put 3 as the next digit of the answer. 
Result so far: 97996.53
Subtracting 1929 from 2150 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 11:
When dividing 2210 by 643, we get 3 with a remainder of 281.
The next digit of our result is 3. 
Result so far: 97996.533
Subtracting 1929 from 2210 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

The final result is 97996.533 with a remainder of 0.0281.
