81244214 ÷ 502 
Our goal is to divide 81244214 by 502.

On to step 1:
502 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 502

Let's proceed to step 2:
If we divide 81 by 502, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 502

Let's proceed to step 3:
812 divided by 502 is 1 with a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 502 away from 812, we end up with 310.
Bring next digit (4) of the dividend behind the 310 and repeat the process: 3104 / 502

Step 4:
3104 divided by 502 is 6 with a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 3012 away from 3104, we end up with 92.
Append the next digit (4) from the dividend to 92 and continue with: 924 / 502

Step 5:
502 goes into 924 1 times with a remainder of 422.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Deduct 502 from 924 and we're left with 422.
Grab the next digit (2) from the dividend, add it to 422, then carry on: 4222 / 502

Advancing to step 6:
If we divide 4222 by 502, we get 8 and a remainder of 206.
Use 8 as the next digit of our solution. 
Result so far: 1618.0
Subtracting 4016 from 4222 leaves us with 206.
Grab the next digit (1) from the dividend, add it to 206, then carry on: 2061 / 502

Advancing to step 7:
If we divide 2061 by 502, we get 4 and a remainder of 53.
The next digit of our result is 4. 
Result so far: 16184.0
If we take 2008 away from 2061, we end up with 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 502

On to step 8:
When dividing 534 by 502, we get 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 161841.0
If we subtract 502 from 534, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
If we divide 320 by 502, we get 0 and a remainder of 320.
The next digit of our result is 0. 
Result so far: 161841.0
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
If we divide 3200 by 502, we get 6 and a remainder of 188.
Write down 6 as next digit of the result. 
Result so far: 161841.06
Deduct 3012 from 3200 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 11:
When dividing 1880 by 502, we get 3 with a remainder of 374.
The next digit of our result is 3. 
Result so far: 161841.063
If we take 1506 away from 1880, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 12:
The number 502 fits into 3740 7 times, leaving a remainder of 226.
Use 7 as the next digit of our solution. 
Result so far: 161841.0637
If we take 3514 away from 3740, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 13:
When dividing 2260 by 502, we get 4 with a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 161841.06374
If we subtract 2008 from 2260, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 14:
502 goes into 2520 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 161841.063745
If we take 2510 away from 2520, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
502 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 161841.063745
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
The number 502 fits into 1000 1 times, leaving a remainder of 498.
The number 1 becomes the next digit in our result. 
Result so far: 161841.06374501
If we subtract 502 from 1000, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

The final result is 161841.06374501 with a remainder of 4.98e-07.
