We're dividing 63258299 by 13 
We want to figure out the number of times 63258299 can be divided by 13.

Moving on to step 1:
If we divide 6 by 13, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 13

On to step 2:
63 divided by 13 is 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 52 from 63, we get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 13

Step 3:
112 divided by 13 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
The remainder is 8 after subtracting 104 from 112.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 13

Let's proceed to step 4:
When dividing 85 by 13, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 486.0
If we subtract 78 from 85, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 13

On to step 5:
If we divide 78 by 13, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 4866.0
Subtract 78 from 78 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 13

On to step 6:
13 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 48660.0
If we take 0 away from 2, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 13

On to step 7:
13 can be fit into 29 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 486602.0
Subtract 26 from 29 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 13

Moving on to step 8:
The number 13 fits into 39 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 4866023.0
Deduct 39 from 39 and we're left 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.

Let's proceed to step 9:
The number 13 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4866023.0
Deduct 0 from 0 and we're left 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.

Going ahead to step 10:
13 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4866023.0
Subtracting 0 from 0 leaves us 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 final result is 4866023.0 with a remainder of 0.0.
