163931 ÷ 63 
Let's see how many times 63 fits into 163931.

Step 1:
The number 63 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 63

Step 2:
63 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 63

On to step 3:
63 goes into 163 2 times with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 37 after subtracting 126 from 163.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 63

On to step 4:
63 goes into 379 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we subtract 378 from 379, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 63

Let's proceed to step 5:
If we divide 13 by 63, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 260.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 63

Step 6:
When dividing 131 by 63, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2602.0
The remainder is 5 after subtracting 126 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 63, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 2602.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
The number 63 fits into 500 7 times, leaving a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 2602.07
Subtract 441 from 500 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
590 divided by 63 is 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 2602.079
The remainder is 23 after subtracting 567 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
63 can be fit into 230 3 times, resulting in a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 2602.0793
If we subtract 189 from 230, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 11:
410 divided by 63 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 2602.07936
The remainder is 32 after subtracting 378 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
The number 63 fits into 320 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 2602.079365
Subtracting 315 from 320 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
When dividing 50 by 63, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 2602.079365
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
63 goes into 500 7 times with a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 2602.07936507
If we subtract 441 from 500, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 2602.07936507 and a remainder of 5.9e-08.
