63596977 ÷ 15 
We want to divide 63596977 by 15.

Step 1:
6 divided by 15 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 15

On to step 2:
If we divide 63 by 15, we get 4 and a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 60 from 63 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 15

Let's proceed to step 3:
If we divide 35 by 15, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 30 from 35 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 15

On to step 4:
15 goes into 59 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 423.0
Subtract 45 from 59 to get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 15

Going ahead to step 5:
If we divide 146 by 15, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 4239.0
Subtracting 135 from 146 leaves us with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 15

Going ahead to step 6:
When dividing 119 by 15, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 42397.0
Subtracting 105 from 119 leaves us with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 15

Going ahead to step 7:
When dividing 147 by 15, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 423979.0
Subtracting 135 from 147 leaves us with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 15

Step 8:
15 goes into 127 8 times with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 4239798.0
Deduct 120 from 127 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
70 divided by 15 is 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4239798.4
Subtract 60 from 70 to 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.

Step 10:
15 goes into 100 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 4239798.46
If we subtract 90 from 100, 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.

Let's proceed to step 11:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 4239798.466
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 4239798.466 and a remainder of 0.001.
