We look at the division of 63217699 by 455 
Our goal is to divide 63217699 by 455.

Step 1:
455 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 455

On to step 2:
63 divided by 455 is 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Append the next digit (2) from the dividend to 63 and continue with: 632 / 455

Advancing to step 3:
The number 455 fits into 632 1 times, leaving a remainder of 177.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 177 after subtracting 455 from 632.
Grab the next digit (1) from the dividend, add it to 177, then carry on: 1771 / 455

Advancing to step 4:
The number 455 fits into 1771 3 times, leaving a remainder of 406.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1365 from 1771, we get 406.
Take the next digit (7) from the dividend and append it to 406, then repeat: 4067 / 455

Let's proceed to step 5:
455 goes into 4067 8 times with a remainder of 427.
Write down 8 as next digit of the result. 
Result so far: 138.0
Deduct 3640 from 4067 and we're left with 427.
Take the next digit (6) from the dividend and append it to 427, then repeat: 4276 / 455

Advancing to step 6:
If we divide 4276 by 455, we get 9 and a remainder of 181.
Record the quotient 9 as the next digit in the result. 
Result so far: 1389.0
Subtract 4095 from 4276 to get 181.
Take the next digit (9) from the dividend and append it to 181, then repeat: 1819 / 455

Let's proceed to step 7:
If we divide 1819 by 455, we get 3 and a remainder of 454.
Write down 3 as next digit of the result. 
Result so far: 13893.0
If we subtract 1365 from 1819, we get 454.
Grab the next digit (9) from the dividend, add it to 454, then carry on: 4549 / 455

Going ahead to step 8:
The number 455 fits into 4549 9 times, leaving a remainder of 454.
The number 9 becomes the next digit in our result. 
Result so far: 138939.0
Subtract 4095 from 4549 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 9:
455 goes into 4540 9 times with a remainder of 445.
Record the quotient 9 as the next digit in the result. 
Result so far: 138939.9
If we subtract 4095 from 4540, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 10:
If we divide 4450 by 455, we get 9 and a remainder of 355.
Use 9 as the next digit of our solution. 
Result so far: 138939.99
Deduct 4095 from 4450 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

The final outcome is 138939.99, with a leftover of 0.355.
