We look at the division of 86950475 by 502 
Our goal is to divide 86950475 by 502.

Step 1:
When dividing 8 by 502, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 502

Advancing to step 2:
When dividing 86 by 502, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 502

Moving on to step 3:
502 can be fit into 869 1 times, resulting in a remainder of 367.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 502 from 869, we get 367.
Take the next digit (5) from the dividend and append it to 367, then repeat: 3675 / 502

Let's proceed to step 4:
When dividing 3675 by 502, we get 7 with a remainder of 161.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 3514 away from 3675, we end up with 161.
Append the next digit (0) from the dividend to 161 and continue with: 1610 / 502

Step 5:
1610 divided by 502 is 3 with a remainder of 104.
The next digit of our result is 3. 
Result so far: 173.0
Deduct 1506 from 1610 and we're left with 104.
Grab the next digit (4) from the dividend, add it to 104, then carry on: 1044 / 502

Let's proceed to step 6:
The number 502 fits into 1044 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1732.0
The remainder is 40 after subtracting 1004 from 1044.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 502

Step 7:
502 goes into 407 0 times with a remainder of 407.
Use 0 as the next digit of our solution. 
Result so far: 17320.0
Deduct 0 from 407 and we're left with 407.
Fetch the next digit (5) from the dividend, attach it to 407 and continue: 4075 / 502

Moving on to step 8:
When dividing 4075 by 502, we get 8 with a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 173208.0
The remainder is 59 after subtracting 4016 from 4075.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
502 goes into 590 1 times with a remainder of 88.
Put 1 as the next digit of the answer. 
Result so far: 173208.1
The remainder is 88 after subtracting 502 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
502 goes into 880 1 times with a remainder of 378.
Put 1 as the next digit of the answer. 
Result so far: 173208.11
Subtract 502 from 880 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The quotient of the division is 173208.11, and the remainder is 0.378.
