We divide 80641 by 502
We're looking to find how many times 502 goes into 80641.

Going ahead to step 1:
8 divided by 502 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 502

Moving on to step 2:
If we divide 80 by 502, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (6) from the dividend, attach it to 80 and continue: 806 / 502

Advancing to step 3:
502 goes into 806 1 times with a remainder of 304.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 304 after subtracting 502 from 806.
Append the next digit (4) from the dividend to 304 and continue with: 3044 / 502

Step 4:
3044 divided by 502 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 3012 from 3044 leaves us with 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 502

On to step 5:
When dividing 321 by 502, we get 0 with a remainder of 321.
The next digit of our result is 0. 
Result so far: 160.0
Deduct 0 from 321 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 6:
The number 502 fits into 3210 6 times, leaving a remainder of 198.
Use 6 as the next digit of our solution. 
Result so far: 160.6
If we subtract 3012 from 3210, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 7:
When dividing 1980 by 502, we get 3 with a remainder of 474.
Put 3 as the next digit of the answer. 
Result so far: 160.63
Subtracting 1506 from 1980 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 8:
502 goes into 4740 9 times with a remainder of 222.
Record the quotient 9 as the next digit in the result. 
Result so far: 160.639
Deduct 4518 from 4740 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 9:
2220 divided by 502 is 4 with a remainder of 212.
Write down 4 as next digit of the result. 
Result so far: 160.6394
If we take 2008 away from 2220, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 10:
502 goes into 2120 4 times with a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 160.63944
If we subtract 2008 from 2120, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 160.63944 with a remainder of 0.000112.
