8518488 ÷ 802 
Our goal is to divide 8518488 by 802.

Advancing to step 1:
8 divided by 802 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 802

Going ahead to step 2:
802 goes into 85 0 times with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 802

Going ahead to step 3:
When dividing 851 by 802, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 49 after subtracting 802 from 851.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 802

Let's proceed to step 4:
802 can be fit into 498 0 times, resulting in a remainder of 498.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 498 and we're left with 498.
Grab the next digit (4) from the dividend, add it to 498, then carry on: 4984 / 802

Moving on to step 5:
The number 802 fits into 4984 6 times, leaving a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 106.0
If we subtract 4812 from 4984, we get 172.
Include the next digit (8) from the dividend after 172, then repeat: 1728 / 802

Step 6:
1728 divided by 802 is 2 with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 1062.0
If we subtract 1604 from 1728, we get 124.
Include the next digit (8) from the dividend after 124, then repeat: 1248 / 802

On to step 7:
1248 divided by 802 is 1 with a remainder of 446.
The next digit of our result is 1. 
Result so far: 10621.0
The remainder is 446 after subtracting 802 from 1248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Going ahead to step 8:
If we divide 4460 by 802, we get 5 and a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 10621.5
Deduct 4010 from 4460 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 9:
4500 divided by 802 is 5 with a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 10621.55
If we take 4010 away from 4500, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The quotient of the division is 10621.55, and the remainder is 0.49.
