We divide 80286313 by 63
We want to figure out the number of times 80286313 can be divided by 63.

Step 1:
The number 63 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 63

Step 2:
80 divided by 63 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 63 from 80 leaves us with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 63

Advancing to step 3:
172 divided by 63 is 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 12.0
If we take 126 away from 172, we end up with 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 63

Step 4:
The number 63 fits into 468 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 441 from 468, we get 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 63

Going ahead to step 5:
The number 63 fits into 276 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 1274.0
The remainder is 24 after subtracting 252 from 276.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 63

Going ahead to step 6:
63 goes into 243 3 times with a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 12743.0
Subtracting 189 from 243 leaves us with 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 63

On to step 7:
63 goes into 541 8 times with a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 127438.0
The remainder is 37 after subtracting 504 from 541.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 63

Step 8:
When dividing 373 by 63, we get 5 with a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 1274385.0
If we take 315 away from 373, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
63 goes into 580 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 1274385.9
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
The number 63 fits into 130 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 1274385.92
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
The number 63 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 1274385.92
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 63, we get 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 1274385.9206
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
When dividing 220 by 63, we get 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 1274385.92063
Deduct 189 from 220 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
If we divide 310 by 63, we get 4 and a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 1274385.920634
Subtracting 252 from 310 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 15:
If we divide 580 by 63, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 1274385.9206349
Subtracting 567 from 580 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 16:
130 divided by 63 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1274385.92063492
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 1274385.92063492 with a balance of 4e-09.
