We're dividing 63402404 by 526 
Let's see how many times 526 fits into 63402404.

On to step 1:
When dividing 6 by 526, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 526

Advancing to step 2:
63 divided by 526 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 526

Advancing to step 3:
634 divided by 526 is 1 with a remainder of 108.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 108 after subtracting 526 from 634.
Append the next digit (0) from the dividend to 108 and continue with: 1080 / 526

Step 4:
1080 divided by 526 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1052 from 1080 leaves us with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 526

Advancing to step 5:
526 can be fit into 282 0 times, resulting in a remainder of 282.
Write down 0 as next digit of the result. 
Result so far: 120.0
The remainder is 282 after subtracting 0 from 282.
Take the next digit (4) from the dividend and append it to 282, then repeat: 2824 / 526

Let's proceed to step 6:
If we divide 2824 by 526, we get 5 and a remainder of 194.
The number 5 becomes the next digit in our result. 
Result so far: 1205.0
If we take 2630 away from 2824, we end up with 194.
Include the next digit (0) from the dividend after 194, then repeat: 1940 / 526

Step 7:
1940 divided by 526 is 3 with a remainder of 362.
The next digit of our result is 3. 
Result so far: 12053.0
If we subtract 1578 from 1940, we get 362.
Append the next digit (4) from the dividend to 362 and continue with: 3624 / 526

On to step 8:
3624 divided by 526 is 6 with a remainder of 468.
The next digit of our result is 6. 
Result so far: 120536.0
If we take 3156 away from 3624, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 9:
The number 526 fits into 4680 8 times, leaving a remainder of 472.
Put 8 as the next digit of the answer. 
Result so far: 120536.8
If we subtract 4208 from 4680, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 10:
When dividing 4720 by 526, we get 8 with a remainder of 512.
Write down 8 as next digit of the result. 
Result so far: 120536.88
Deduct 4208 from 4720 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The quotient of the division is 120536.88, and the remainder is 0.512.
