63995145 divided by 415 
Our goal is to divide 63995145 by 415.

On to step 1:
415 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 415

On to step 2:
415 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 415

Step 3:
If we divide 639 by 415, we get 1 and a remainder of 224.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 415 from 639 leaves us with 224.
Fetch the next digit (9) from the dividend, attach it to 224 and continue: 2249 / 415

Going ahead to step 4:
2249 divided by 415 is 5 with a remainder of 174.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2075 from 2249 to get 174.
Bring next digit (5) of the dividend behind the 174 and repeat the process: 1745 / 415

Moving on to step 5:
415 goes into 1745 4 times with a remainder of 85.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtracting 1660 from 1745 leaves us with 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 415

Going ahead to step 6:
415 can be fit into 851 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 1542.0
Subtracting 830 from 851 leaves us with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 415

Advancing to step 7:
415 goes into 214 0 times with a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 15420.0
Subtract 0 from 214 to get 214.
Take the next digit (5) from the dividend and append it to 214, then repeat: 2145 / 415

On to step 8:
2145 divided by 415 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 154205.0
Subtracting 2075 from 2145 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
If we divide 700 by 415, we get 1 and a remainder of 285.
Put 1 as the next digit of the answer. 
Result so far: 154205.1
Deduct 415 from 700 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 10:
415 can be fit into 2850 6 times, resulting in a remainder of 360.
Record the quotient 6 as the next digit in the result. 
Result so far: 154205.16
If we subtract 2490 from 2850, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 11:
415 goes into 3600 8 times with a remainder of 280.
The next digit of our result is 8. 
Result so far: 154205.168
The remainder is 280 after subtracting 3320 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
415 can be fit into 2800 6 times, resulting in a remainder of 310.
Record the quotient 6 as the next digit in the result. 
Result so far: 154205.1686
Deduct 2490 from 2800 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 13:
3100 divided by 415 is 7 with a remainder of 195.
Use 7 as the next digit of our solution. 
Result so far: 154205.16867
If we take 2905 away from 3100, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 14:
415 can be fit into 1950 4 times, resulting in a remainder of 290.
The number 4 becomes the next digit in our result. 
Result so far: 154205.168674
Deduct 1660 from 1950 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 15:
If we divide 2900 by 415, we get 6 and a remainder of 410.
Put 6 as the next digit of the answer. 
Result so far: 154205.1686746
If we take 2490 away from 2900, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 16:
415 goes into 4100 9 times with a remainder of 365.
Record the quotient 9 as the next digit in the result. 
Result so far: 154205.16867469
If we take 3735 away from 4100, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

After the division, we end up with 154205.16867469 and a remainder of 3.65e-07.
