We look at the division of 81486146 by 502 
Let's see how many times 502 fits into 81486146.

Advancing to step 1:
502 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 502

On to step 2:
81 divided by 502 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (4) of the dividend behind the 81 and repeat the process: 814 / 502

On to step 3:
814 divided by 502 is 1 with a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 502 from 814 and we're left with 312.
Take the next digit (8) from the dividend and append it to 312, then repeat: 3128 / 502

Going ahead to step 4:
3128 divided by 502 is 6 with a remainder of 116.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 3012 from 3128 to get 116.
Fetch the next digit (6) from the dividend, attach it to 116 and continue: 1166 / 502

On to step 5:
If we divide 1166 by 502, we get 2 and a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 162.0
Subtract 1004 from 1166 to get 162.
Fetch the next digit (1) from the dividend, attach it to 162 and continue: 1621 / 502

Advancing to step 6:
The number 502 fits into 1621 3 times, leaving a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 1623.0
Subtracting 1506 from 1621 leaves us with 115.
Bring next digit (4) of the dividend behind the 115 and repeat the process: 1154 / 502

Let's proceed to step 7:
502 can be fit into 1154 2 times, resulting in a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 16232.0
Deduct 1004 from 1154 and we're left with 150.
Append the next digit (6) from the dividend to 150 and continue with: 1506 / 502

Step 8:
502 goes into 1506 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 162323.0
If we subtract 1506 from 1506, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 502 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 162323.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 502 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 162323.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 162323.0, with a leftover of 0.0.
