We look at the division of 63539317 by 864 
Our goal is to divide 63539317 by 864.

Step 1:
864 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 864

Moving on to step 2:
When dividing 63 by 864, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 864

On to step 3:
864 can be fit into 635 0 times, resulting in a remainder of 635.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 635 to get 635.
Bring next digit (3) of the dividend behind the 635 and repeat the process: 6353 / 864

Step 4:
864 goes into 6353 7 times with a remainder of 305.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 6048 from 6353, we get 305.
Fetch the next digit (9) from the dividend, attach it to 305 and continue: 3059 / 864

On to step 5:
3059 divided by 864 is 3 with a remainder of 467.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Deduct 2592 from 3059 and we're left with 467.
Fetch the next digit (3) from the dividend, attach it to 467 and continue: 4673 / 864

Let's proceed to step 6:
The number 864 fits into 4673 5 times, leaving a remainder of 353.
Record the quotient 5 as the next digit in the result. 
Result so far: 735.0
The remainder is 353 after subtracting 4320 from 4673.
Fetch the next digit (1) from the dividend, attach it to 353 and continue: 3531 / 864

On to step 7:
864 goes into 3531 4 times with a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 7354.0
Subtract 3456 from 3531 to get 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 864

Step 8:
757 divided by 864 is 0 with a remainder of 757.
Use 0 as the next digit of our solution. 
Result so far: 73540.0
If we take 0 away from 757, we end up with 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Step 9:
864 can be fit into 7570 8 times, resulting in a remainder of 658.
Put 8 as the next digit of the answer. 
Result so far: 73540.8
Subtract 6912 from 7570 to get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Let's proceed to step 10:
6580 divided by 864 is 7 with a remainder of 532.
Put 7 as the next digit of the answer. 
Result so far: 73540.87
Subtract 6048 from 6580 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 11:
5320 divided by 864 is 6 with a remainder of 136.
The next digit of our result is 6. 
Result so far: 73540.876
If we take 5184 away from 5320, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 12:
When dividing 1360 by 864, we get 1 with a remainder of 496.
The number 1 becomes the next digit in our result. 
Result so far: 73540.8761
Subtracting 864 from 1360 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 13:
When dividing 4960 by 864, we get 5 with a remainder of 640.
Record the quotient 5 as the next digit in the result. 
Result so far: 73540.87615
The remainder is 640 after subtracting 4320 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 14:
864 goes into 6400 7 times with a remainder of 352.
Use 7 as the next digit of our solution. 
Result so far: 73540.876157
If we take 6048 away from 6400, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 15:
864 can be fit into 3520 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 73540.8761574
Subtracting 3456 from 3520 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 16:
When dividing 640 by 864, we get 0 with a remainder of 640.
The next digit of our result is 0. 
Result so far: 73540.8761574
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The quotient of the division is 73540.8761574, and the remainder is 6.4e-07.
