We look at the division of 40689177 by 502 
We want to figure out the number of times 40689177 can be divided by 502.

On to step 1:
502 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 502

Going ahead to step 2:
When dividing 40 by 502, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 502

Going ahead to step 3:
502 can be fit into 406 0 times, resulting in a remainder of 406.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 406 leaves us with 406.
Grab the next digit (8) from the dividend, add it to 406, then carry on: 4068 / 502

Moving on to step 4:
When dividing 4068 by 502, we get 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 52 after subtracting 4016 from 4068.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 502

Advancing to step 5:
529 divided by 502 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 81.0
Subtracting 502 from 529 leaves us with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 502

Moving on to step 6:
If we divide 271 by 502, we get 0 and a remainder of 271.
Write down 0 as next digit of the result. 
Result so far: 810.0
Deduct 0 from 271 and we're left with 271.
Append the next digit (7) from the dividend to 271 and continue with: 2717 / 502

On to step 7:
The number 502 fits into 2717 5 times, leaving a remainder of 207.
The next digit of our result is 5. 
Result so far: 8105.0
If we subtract 2510 from 2717, we get 207.
Include the next digit (7) from the dividend after 207, then repeat: 2077 / 502

Step 8:
If we divide 2077 by 502, we get 4 and a remainder of 69.
The next digit of our result is 4. 
Result so far: 81054.0
Subtracting 2008 from 2077 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
502 can be fit into 690 1 times, resulting in a remainder of 188.
Put 1 as the next digit of the answer. 
Result so far: 81054.1
The remainder is 188 after subtracting 502 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 10:
If we divide 1880 by 502, we get 3 and a remainder of 374.
Write down 3 as next digit of the result. 
Result so far: 81054.13
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.

Step 11:
If we divide 3740 by 502, we get 7 and a remainder of 226.
The number 7 becomes the next digit in our result. 
Result so far: 81054.137
Deduct 3514 from 3740 and we're left 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.

Going ahead to step 12:
The number 502 fits into 2260 4 times, leaving a remainder of 252.
The number 4 becomes the next digit in our result. 
Result so far: 81054.1374
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.

Going ahead to step 13:
When dividing 2520 by 502, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 81054.13745
Subtracting 2510 from 2520 leaves us 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.

Going ahead to step 14:
502 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 81054.13745
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
502 goes into 1000 1 times with a remainder of 498.
Use 1 as the next digit of our solution. 
Result so far: 81054.1374501
Subtracting 502 from 1000 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Moving on to step 16:
When dividing 4980 by 502, we get 9 with a remainder of 462.
Record the quotient 9 as the next digit in the result. 
Result so far: 81054.13745019
If we take 4518 away from 4980, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

In conclusion, the division gives 81054.13745019 with a balance of 4.62e-07.
