We look at the division of 63405385 by 315 
We want to divide 63405385 by 315.

Step 1:
315 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 315

Step 2:
315 goes into 63 0 times with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 315

On to step 3:
634 divided by 315 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we take 630 away from 634, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 315

On to step 4:
315 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 40 leaves us with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 315

Going ahead to step 5:
315 goes into 405 1 times with a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 201.0
If we take 315 away from 405, we end up with 90.
Bring next digit (3) of the dividend behind the 90 and repeat the process: 903 / 315

On to step 6:
When dividing 903 by 315, we get 2 with a remainder of 273.
The number 2 becomes the next digit in our result. 
Result so far: 2012.0
Deduct 630 from 903 and we're left with 273.
Bring next digit (8) of the dividend behind the 273 and repeat the process: 2738 / 315

On to step 7:
2738 divided by 315 is 8 with a remainder of 218.
The next digit of our result is 8. 
Result so far: 20128.0
Subtract 2520 from 2738 to get 218.
Fetch the next digit (5) from the dividend, attach it to 218 and continue: 2185 / 315

On to step 8:
2185 divided by 315 is 6 with a remainder of 295.
Write down 6 as next digit of the result. 
Result so far: 201286.0
Deduct 1890 from 2185 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 9:
315 goes into 2950 9 times with a remainder of 115.
Record the quotient 9 as the next digit in the result. 
Result so far: 201286.9
If we take 2835 away from 2950, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 10:
315 goes into 1150 3 times with a remainder of 205.
The number 3 becomes the next digit in our result. 
Result so far: 201286.93
Subtract 945 from 1150 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 11:
When dividing 2050 by 315, we get 6 with a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 201286.936
Deduct 1890 from 2050 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
315 can be fit into 1600 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 201286.9365
Subtract 1575 from 1600 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
If we divide 250 by 315, we get 0 and a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 201286.9365
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
315 goes into 2500 7 times with a remainder of 295.
Record the quotient 7 as the next digit in the result. 
Result so far: 201286.936507
Subtract 2205 from 2500 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 15:
315 goes into 2950 9 times with a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 201286.9365079
Deduct 2835 from 2950 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 16:
The number 315 fits into 1150 3 times, leaving a remainder of 205.
The number 3 becomes the next digit in our result. 
Result so far: 201286.93650793
If we subtract 945 from 1150, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

In conclusion, the division gives 201286.93650793 with a balance of 2.05e-07.
