We look at the division of 63504916 by 400 
We want to divide 63504916 by 400.

Let's proceed to step 1:
When dividing 6 by 400, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 400

Going ahead to step 2:
When dividing 63 by 400, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Take the next digit (5) from the dividend and append it to 63, then repeat: 635 / 400

Advancing to step 3:
When dividing 635 by 400, we get 1 with a remainder of 235.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 400 away from 635, we end up with 235.
Bring next digit (0) of the dividend behind the 235 and repeat the process: 2350 / 400

Let's proceed to step 4:
If we divide 2350 by 400, we get 5 and a remainder of 350.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 350 after subtracting 2000 from 2350.
Include the next digit (4) from the dividend after 350, then repeat: 3504 / 400

Moving on to step 5:
If we divide 3504 by 400, we get 8 and a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Subtracting 3200 from 3504 leaves us with 304.
Take the next digit (9) from the dividend and append it to 304, then repeat: 3049 / 400

On to step 6:
If we divide 3049 by 400, we get 7 and a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 1587.0
Deduct 2800 from 3049 and we're left with 249.
Append the next digit (1) from the dividend to 249 and continue with: 2491 / 400

On to step 7:
The number 400 fits into 2491 6 times, leaving a remainder of 91.
Write down 6 as next digit of the result. 
Result so far: 15876.0
The remainder is 91 after subtracting 2400 from 2491.
Grab the next digit (6) from the dividend, add it to 91, then carry on: 916 / 400

Let's proceed to step 8:
400 can be fit into 916 2 times, resulting in a remainder of 116.
Write down 2 as next digit of the result. 
Result so far: 158762.0
Subtracting 800 from 916 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 9:
400 can be fit into 1160 2 times, resulting in a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 158762.2
Subtract 800 from 1160 to 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.

Step 10:
400 goes into 3600 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 158762.29
The remainder is 0 after subtracting 3600 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
If we divide 0 by 400, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 158762.29
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
400 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 158762.29
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 158762.29, and the remainder is 0.0.
