Let's divide 643850 by 63
Let's see how many times 63 fits into 643850.

Let's proceed to step 1:
If we divide 6 by 63, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 63

Let's proceed to step 2:
63 goes into 64 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 63 from 64, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 63

Moving on to step 3:
63 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 63

Step 4:
63 goes into 138 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtract 126 from 138 to get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 63

Going ahead to step 5:
63 can be fit into 125 1 times, resulting in a remainder of 62.
The next digit of our result is 1. 
Result so far: 1021.0
Deduct 63 from 125 and we're left with 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 63

Let's proceed to step 6:
The number 63 fits into 620 9 times, leaving a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 10219.0
If we subtract 567 from 620, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
63 can be fit into 530 8 times, resulting in a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 10219.8
If we subtract 504 from 530, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
63 goes into 260 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 10219.84
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 63, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 10219.841
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
63 can be fit into 170 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 10219.8412
Subtracting 126 from 170 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
The number 63 fits into 440 6 times, leaving a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 10219.84126
Subtracting 378 from 440 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
63 goes into 620 9 times with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 10219.841269
If we subtract 567 from 620, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 13:
If we divide 530 by 63, we get 8 and a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 10219.8412698
Subtract 504 from 530 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
63 can be fit into 260 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 10219.84126984
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 10219.84126984, with a leftover of 8e-09.
