We're dividing 86389027 by 502 
We're looking to find how many times 502 goes into 86389027.

Let's proceed to step 1:
8 divided by 502 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 502

Step 2:
If we divide 86 by 502, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 502

On to step 3:
The number 502 fits into 863 1 times, leaving a remainder of 361.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 502 from 863 and we're left with 361.
Include the next digit (8) from the dividend after 361, then repeat: 3618 / 502

On to step 4:
The number 502 fits into 3618 7 times, leaving a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 3514 from 3618 leaves us with 104.
Grab the next digit (9) from the dividend, add it to 104, then carry on: 1049 / 502

On to step 5:
502 can be fit into 1049 2 times, resulting in a remainder of 45.
The next digit of our result is 2. 
Result so far: 172.0
Subtract 1004 from 1049 to get 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 502

Step 6:
When dividing 450 by 502, we get 0 with a remainder of 450.
The number 0 becomes the next digit in our result. 
Result so far: 1720.0
Subtract 0 from 450 to get 450.
Take the next digit (2) from the dividend and append it to 450, then repeat: 4502 / 502

On to step 7:
502 goes into 4502 8 times with a remainder of 486.
Record the quotient 8 as the next digit in the result. 
Result so far: 17208.0
If we take 4016 away from 4502, we end up with 486.
Grab the next digit (7) from the dividend, add it to 486, then carry on: 4867 / 502

Step 8:
4867 divided by 502 is 9 with a remainder of 349.
The next digit of our result is 9. 
Result so far: 172089.0
If we take 4518 away from 4867, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 9:
3490 divided by 502 is 6 with a remainder of 478.
Write down 6 as next digit of the result. 
Result so far: 172089.6
If we subtract 3012 from 3490, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 10:
When dividing 4780 by 502, we get 9 with a remainder of 262.
Put 9 as the next digit of the answer. 
Result so far: 172089.69
If we take 4518 away from 4780, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 11:
2620 divided by 502 is 5 with a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 172089.695
Subtracting 2510 from 2620 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 12:
When dividing 1100 by 502, we get 2 with a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 172089.6952
Subtract 1004 from 1100 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
502 goes into 960 1 times with a remainder of 458.
The number 1 becomes the next digit in our result. 
Result so far: 172089.69521
If we subtract 502 from 960, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 14:
If we divide 4580 by 502, we get 9 and a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 172089.695219
If we subtract 4518 from 4580, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 15:
When dividing 620 by 502, we get 1 with a remainder of 118.
Use 1 as the next digit of our solution. 
Result so far: 172089.6952191
The remainder is 118 after subtracting 502 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 16:
When dividing 1180 by 502, we get 2 with a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 172089.69521912
The remainder is 176 after subtracting 1004 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final result is 172089.69521912 with a remainder of 1.76e-07.
