Let's divide 72945186 by 502
We want to divide 72945186 by 502.

On to step 1:
If we divide 7 by 502, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 502

Going ahead to step 2:
When dividing 72 by 502, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 502

Going ahead to step 3:
502 can be fit into 729 1 times, resulting in a remainder of 227.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 227 after subtracting 502 from 729.
Fetch the next digit (4) from the dividend, attach it to 227 and continue: 2274 / 502

Moving on to step 4:
When dividing 2274 by 502, we get 4 with a remainder of 266.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 266 after subtracting 2008 from 2274.
Bring next digit (5) of the dividend behind the 266 and repeat the process: 2665 / 502

Going ahead to step 5:
502 can be fit into 2665 5 times, resulting in a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Subtract 2510 from 2665 to get 155.
Take the next digit (1) from the dividend and append it to 155, then repeat: 1551 / 502

Going ahead to step 6:
The number 502 fits into 1551 3 times, leaving a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 1453.0
Deduct 1506 from 1551 and we're left with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 502

Going ahead to step 7:
When dividing 458 by 502, we get 0 with a remainder of 458.
The number 0 becomes the next digit in our result. 
Result so far: 14530.0
Deduct 0 from 458 and we're left with 458.
Fetch the next digit (6) from the dividend, attach it to 458 and continue: 4586 / 502

Moving on to step 8:
If we divide 4586 by 502, we get 9 and a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 145309.0
The remainder is 68 after subtracting 4518 from 4586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
680 divided by 502 is 1 with a remainder of 178.
Put 1 as the next digit of the answer. 
Result so far: 145309.1
Subtract 502 from 680 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 10:
The number 502 fits into 1780 3 times, leaving a remainder of 274.
Write down 3 as next digit of the result. 
Result so far: 145309.13
If we take 1506 away from 1780, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 11:
When dividing 2740 by 502, we get 5 with a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 145309.135
The remainder is 230 after subtracting 2510 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 12:
2300 divided by 502 is 4 with a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 145309.1354
Subtracting 2008 from 2300 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 13:
If we divide 2920 by 502, we get 5 and a remainder of 410.
Write down 5 as next digit of the result. 
Result so far: 145309.13545
If we take 2510 away from 2920, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 14:
The number 502 fits into 4100 8 times, leaving a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 145309.135458
The remainder is 84 after subtracting 4016 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 15:
The number 502 fits into 840 1 times, leaving a remainder of 338.
The number 1 becomes the next digit in our result. 
Result so far: 145309.1354581
Subtract 502 from 840 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 16:
If we divide 3380 by 502, we get 6 and a remainder of 368.
The next digit of our result is 6. 
Result so far: 145309.13545816
Subtracting 3012 from 3380 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The quotient of the division is 145309.13545816, and the remainder is 3.68e-07.
