We look at the division of 99586247 by 458 
We want to divide 99586247 by 458.

Step 1:
If we divide 9 by 458, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 458

On to step 2:
If we divide 99 by 458, we get 0 and a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 458

On to step 3:
458 goes into 995 2 times with a remainder of 79.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 916 from 995 leaves us with 79.
Take the next digit (8) from the dividend and append it to 79, then repeat: 798 / 458

Step 4:
The number 458 fits into 798 1 times, leaving a remainder of 340.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 458 from 798 to get 340.
Fetch the next digit (6) from the dividend, attach it to 340 and continue: 3406 / 458

On to step 5:
458 can be fit into 3406 7 times, resulting in a remainder of 200.
Put 7 as the next digit of the answer. 
Result so far: 217.0
Subtract 3206 from 3406 to get 200.
Grab the next digit (2) from the dividend, add it to 200, then carry on: 2002 / 458

Moving on to step 6:
458 goes into 2002 4 times with a remainder of 170.
The next digit of our result is 4. 
Result so far: 2174.0
If we subtract 1832 from 2002, we get 170.
Append the next digit (4) from the dividend to 170 and continue with: 1704 / 458

Advancing to step 7:
The number 458 fits into 1704 3 times, leaving a remainder of 330.
Use 3 as the next digit of our solution. 
Result so far: 21743.0
The remainder is 330 after subtracting 1374 from 1704.
Grab the next digit (7) from the dividend, add it to 330, then carry on: 3307 / 458

Advancing to step 8:
3307 divided by 458 is 7 with a remainder of 101.
Write down 7 as next digit of the result. 
Result so far: 217437.0
Subtract 3206 from 3307 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 9:
458 goes into 1010 2 times with a remainder of 94.
Put 2 as the next digit of the answer. 
Result so far: 217437.2
If we subtract 916 from 1010, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 10:
458 can be fit into 940 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 217437.22
If we take 916 away from 940, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 217437.22 and a remainder of 0.024.
