We're dividing 8455407 by 502 
We want to divide 8455407 by 502.

Let's proceed to step 1:
8 divided by 502 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 502

Advancing to step 2:
502 goes into 84 0 times with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Take the next digit (5) from the dividend and append it to 84, then repeat: 845 / 502

Advancing to step 3:
The number 502 fits into 845 1 times, leaving a remainder of 343.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 502 from 845 to get 343.
Grab the next digit (5) from the dividend, add it to 343, then carry on: 3435 / 502

Advancing to step 4:
The number 502 fits into 3435 6 times, leaving a remainder of 423.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 3012 from 3435 to get 423.
Take the next digit (4) from the dividend and append it to 423, then repeat: 4234 / 502

Advancing to step 5:
4234 divided by 502 is 8 with a remainder of 218.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
Deduct 4016 from 4234 and we're left with 218.
Grab the next digit (0) from the dividend, add it to 218, then carry on: 2180 / 502

Advancing to step 6:
2180 divided by 502 is 4 with a remainder of 172.
The number 4 becomes the next digit in our result. 
Result so far: 1684.0
If we subtract 2008 from 2180, we get 172.
Fetch the next digit (7) from the dividend, attach it to 172 and continue: 1727 / 502

Step 7:
When dividing 1727 by 502, we get 3 with a remainder of 221.
Write down 3 as next digit of the result. 
Result so far: 16843.0
Deduct 1506 from 1727 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Going ahead to step 8:
If we divide 2210 by 502, we get 4 and a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 16843.4
The remainder is 202 after subtracting 2008 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 9:
502 can be fit into 2020 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 16843.44
Subtracting 2008 from 2020 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 16843.44, with a leftover of 0.012.
