We're dividing 63378615 by 458 
We're looking to find how many times 458 goes into 63378615.

Step 1:
458 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 458

On to step 2:
The number 458 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 458

Let's proceed to step 3:
458 goes into 633 1 times with a remainder of 175.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 458 from 633 to get 175.
Fetch the next digit (7) from the dividend, attach it to 175 and continue: 1757 / 458

Advancing to step 4:
When dividing 1757 by 458, we get 3 with a remainder of 383.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 383 after subtracting 1374 from 1757.
Fetch the next digit (8) from the dividend, attach it to 383 and continue: 3838 / 458

Step 5:
458 can be fit into 3838 8 times, resulting in a remainder of 174.
Write down 8 as next digit of the result. 
Result so far: 138.0
If we subtract 3664 from 3838, we get 174.
Append the next digit (6) from the dividend to 174 and continue with: 1746 / 458

Let's proceed to step 6:
458 can be fit into 1746 3 times, resulting in a remainder of 372.
The number 3 becomes the next digit in our result. 
Result so far: 1383.0
The remainder is 372 after subtracting 1374 from 1746.
Append the next digit (1) from the dividend to 372 and continue with: 3721 / 458

Going ahead to step 7:
When dividing 3721 by 458, we get 8 with a remainder of 57.
The number 8 becomes the next digit in our result. 
Result so far: 13838.0
Subtracting 3664 from 3721 leaves us with 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 458

Moving on to step 8:
The number 458 fits into 575 1 times, leaving a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 138381.0
The remainder is 117 after subtracting 458 from 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 9:
458 can be fit into 1170 2 times, resulting in a remainder of 254.
The number 2 becomes the next digit in our result. 
Result so far: 138381.2
The remainder is 254 after subtracting 916 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 10:
458 can be fit into 2540 5 times, resulting in a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 138381.25
If we subtract 2290 from 2540, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 11:
When dividing 2500 by 458, we get 5 with a remainder of 210.
The next digit of our result is 5. 
Result so far: 138381.255
If we subtract 2290 from 2500, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

In conclusion, the division gives 138381.255 with a balance of 0.021.
