When dividing 5 by 455, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 455

Advancing to step 2:
56 divided by 455 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Fetch the next digit (0) from the dividend, attach it to 56 and continue: 560 / 455

Let's proceed to step 3:
455 goes into 560 1 times with a remainder of 105.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 455 from 560, we get 105.
Grab the next digit (0) from the dividend, add it to 105, then carry on: 1050 / 455

Step 4:
455 can be fit into 1050 2 times, resulting in a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 910 from 1050 to get 140.
Take the next digit (4) from the dividend and append it to 140, then repeat: 1404 / 455

Moving on to step 5:
When dividing 1404 by 455, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 123.0
Subtract 1365 from 1404 to get 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 455

Step 6:
455 goes into 395 0 times with a remainder of 395.
Write down 0 as next digit of the result. 
Result so far: 1230.0
Deduct 0 from 395 and we're left with 395.
Append the next digit (7) from the dividend to 395 and continue with: 3957 / 455

Going ahead to step 7:
When dividing 3957 by 455, we get 8 with a remainder of 317.
Use 8 as the next digit of our solution. 
Result so far: 12308.0
Subtracting 3640 from 3957 leaves us with 317.
Include the next digit (8) from the dividend after 317, then repeat: 3178 / 455

Going ahead to step 8:
The number 455 fits into 3178 6 times, leaving a remainder of 448.
Write down 6 as next digit of the result. 
Result so far: 123086.0
Subtract 2730 from 3178 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 9:
4480 divided by 455 is 9 with a remainder of 385.
Record the quotient 9 as the next digit in the result. 
Result so far: 123086.9
If we take 4095 away from 4480, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 10:
455 can be fit into 3850 8 times, resulting in a remainder of 210.
Put 8 as the next digit of the answer. 
Result so far: 123086.98
The remainder is 210 after subtracting 3640 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 11:
455 can be fit into 2100 4 times, resulting in a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 123086.984
Subtracting 1820 from 2100 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
The number 455 fits into 2800 6 times, leaving a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 123086.9846
The remainder is 70 after subtracting 2730 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
455 can be fit into 700 1 times, resulting in a remainder of 245.
The next digit of our result is 1. 
Result so far: 123086.98461
If we take 455 away from 700, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 14:
If we divide 2450 by 455, we get 5 and a remainder of 175.
The next digit of our result is 5. 
Result so far: 123086.984615
The remainder is 175 after subtracting 2275 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 15:
455 can be fit into 1750 3 times, resulting in a remainder of 385.
Put 3 as the next digit of the answer. 
Result so far: 123086.9846153
Subtract 1365 from 1750 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 16:
3850 divided by 455 is 8 with a remainder of 210.
Write down 8 as next digit of the result. 
Result so far: 123086.98461538
Deduct 3640 from 3850 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 123086.98461538, with a leftover of 2.1e-07.
