Let's divide 63864145 by 81
Our goal is to divide 63864145 by 81.

Let's proceed to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 81

Moving on to step 2:
81 goes into 63 0 times with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 81

Advancing to step 3:
81 can be fit into 638 7 times, resulting in a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 71 after subtracting 567 from 638.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 81

Going ahead to step 4:
81 can be fit into 716 8 times, resulting in a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we subtract 648 from 716, we get 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 81

Step 5:
81 goes into 684 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 788.0
Subtract 648 from 684 to get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 81

On to step 6:
When dividing 361 by 81, we get 4 with a remainder of 37.
The next digit of our result is 4. 
Result so far: 7884.0
If we subtract 324 from 361, we get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 81

On to step 7:
The number 81 fits into 374 4 times, leaving a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 78844.0
Subtracting 324 from 374 leaves us with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 81

Moving on to step 8:
When dividing 505 by 81, we get 6 with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 788446.0
If we take 486 away from 505, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
When dividing 190 by 81, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 788446.2
Subtracting 162 from 190 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
The number 81 fits into 280 3 times, leaving a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 788446.23
Deduct 243 from 280 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
81 can be fit into 370 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 788446.234
Deduct 324 from 370 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
If we divide 460 by 81, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 788446.2345
If we subtract 405 from 460, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 13:
81 goes into 550 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 788446.23456
Subtract 486 from 550 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
640 divided by 81 is 7 with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 788446.234567
The remainder is 73 after subtracting 567 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 15:
The number 81 fits into 730 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 788446.2345679
If we subtract 729 from 730, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 16:
81 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 788446.2345679
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 788446.2345679, and the remainder is 1e-08.
