803988 ÷ 63 
We want to figure out the number of times 803988 can be divided by 63.

Going ahead to step 1:
63 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 63

Advancing to step 2:
63 goes into 80 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 63 from 80 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 63

Advancing to step 3:
If we divide 173 by 63, we get 2 and a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 126 from 173, we get 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 63

Moving on to step 4:
The number 63 fits into 479 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
The remainder is 38 after subtracting 441 from 479.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 63

Going ahead to step 5:
63 goes into 388 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 1276.0
Subtracting 378 from 388 leaves us with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 63

On to step 6:
If we divide 108 by 63, we get 1 and a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 12761.0
Deduct 63 from 108 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
When dividing 450 by 63, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 12761.7
If we take 441 away from 450, we end up 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.

Step 8:
The number 63 fits into 90 1 times, leaving a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 12761.71
If we subtract 63 from 90, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
If we divide 270 by 63, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 12761.714
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
When dividing 180 by 63, we get 2 with a remainder of 54.
The next digit of our result is 2. 
Result so far: 12761.7142
If we take 126 away from 180, we end up 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.

Going ahead to step 11:
540 divided by 63 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 12761.71428
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
63 can be fit into 360 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 12761.714285
Subtracting 315 from 360 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 13:
If we divide 450 by 63, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 12761.7142857
If we subtract 441 from 450, we get 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 14:
90 divided by 63 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 12761.71428571
Subtract 63 from 90 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 12761.71428571 with a balance of 2.7e-08.
