We look at the division of 63997581 by 415 
Let's see how many times 415 fits into 63997581.

Advancing to step 1:
If we divide 6 by 415, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 415

On to step 2:
When dividing 63 by 415, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 415

Moving on to step 3:
The number 415 fits into 639 1 times, leaving a remainder of 224.
Record the quotient 1 as the next digit in the 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

Step 4:
415 can be fit into 2249 5 times, resulting in a remainder of 174.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 174 after subtracting 2075 from 2249.
Include the next digit (7) from the dividend after 174, then repeat: 1747 / 415

Let's proceed to step 5:
The number 415 fits into 1747 4 times, leaving a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 154.0
If we take 1660 away from 1747, we end up with 87.
Append the next digit (5) from the dividend to 87 and continue with: 875 / 415

Step 6:
415 can be fit into 875 2 times, resulting in a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 1542.0
Subtract 830 from 875 to get 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 415

Let's proceed to step 7:
When dividing 458 by 415, we get 1 with a remainder of 43.
The next digit of our result is 1. 
Result so far: 15421.0
Subtract 415 from 458 to get 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 415

Moving on to step 8:
415 can be fit into 431 1 times, resulting in a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 154211.0
Subtracting 415 from 431 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
415 can be fit into 160 0 times, resulting in a remainder of 160.
The next digit of our result is 0. 
Result so far: 154211.0
If we subtract 0 from 160, we get 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 10:
The number 415 fits into 1600 3 times, leaving a remainder of 355.
Record the quotient 3 as the next digit in the result. 
Result so far: 154211.03
If we subtract 1245 from 1600, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 11:
415 goes into 3550 8 times with a remainder of 230.
Record the quotient 8 as the next digit in the result. 
Result so far: 154211.038
If we subtract 3320 from 3550, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 12:
When dividing 2300 by 415, we get 5 with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 154211.0385
If we subtract 2075 from 2300, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 13:
415 goes into 2250 5 times with a remainder of 175.
The next digit of our result is 5. 
Result so far: 154211.03855
Subtracting 2075 from 2250 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The quotient of the division is 154211.03855, and the remainder is 0.000175.
