Let's divide 63135424 by 904
We want to figure out the number of times 63135424 can be divided by 904.

On to step 1:
If we divide 6 by 904, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 904

Let's proceed to step 2:
When dividing 63 by 904, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 904

On to step 3:
When dividing 631 by 904, we get 0 with a remainder of 631.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 631, we end up with 631.
Include the next digit (3) from the dividend after 631, then repeat: 6313 / 904

Let's proceed to step 4:
904 goes into 6313 6 times with a remainder of 889.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 5424 away from 6313, we end up with 889.
Take the next digit (5) from the dividend and append it to 889, then repeat: 8895 / 904

Let's proceed to step 5:
The number 904 fits into 8895 9 times, leaving a remainder of 759.
The next digit of our result is 9. 
Result so far: 69.0
If we subtract 8136 from 8895, we get 759.
Take the next digit (4) from the dividend and append it to 759, then repeat: 7594 / 904

Advancing to step 6:
When dividing 7594 by 904, we get 8 with a remainder of 362.
Put 8 as the next digit of the answer. 
Result so far: 698.0
If we take 7232 away from 7594, we end up with 362.
Fetch the next digit (2) from the dividend, attach it to 362 and continue: 3622 / 904

Going ahead to step 7:
904 can be fit into 3622 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 6984.0
Deduct 3616 from 3622 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 904

Moving on to step 8:
904 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 69840.0
If we subtract 0 from 64, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
640 divided by 904 is 0 with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 69840.0
Deduct 0 from 640 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 10:
904 can be fit into 6400 7 times, resulting in a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 69840.07
Subtract 6328 from 6400 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
When dividing 720 by 904, we get 0 with a remainder of 720.
Put 0 as the next digit of the answer. 
Result so far: 69840.07
If we take 0 away from 720, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 12:
When dividing 7200 by 904, we get 7 with a remainder of 872.
The next digit of our result is 7. 
Result so far: 69840.0707
Subtract 6328 from 7200 to get 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Let's proceed to step 13:
When dividing 8720 by 904, we get 9 with a remainder of 584.
Record the quotient 9 as the next digit in the result. 
Result so far: 69840.07079
If we subtract 8136 from 8720, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 14:
904 goes into 5840 6 times with a remainder of 416.
The next digit of our result is 6. 
Result so far: 69840.070796
Deduct 5424 from 5840 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 15:
904 goes into 4160 4 times with a remainder of 544.
Record the quotient 4 as the next digit in the result. 
Result so far: 69840.0707964
Deduct 3616 from 4160 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 16:
When dividing 5440 by 904, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 69840.07079646
Subtracting 5424 from 5440 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.

The final result is 69840.07079646 with a remainder of 1.6e-08.
