We look at the division of 49687810 by 509 
We want to figure out the number of times 49687810 can be divided by 509.

Advancing to step 1:
4 divided by 509 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 509

Let's proceed to step 2:
509 goes into 49 0 times with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 509

Moving on to step 3:
If we divide 496 by 509, we get 0 and a remainder of 496.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 496 after subtracting 0 from 496.
Take the next digit (8) from the dividend and append it to 496, then repeat: 4968 / 509

Moving on to step 4:
When dividing 4968 by 509, we get 9 with a remainder of 387.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 4581 from 4968 leaves us with 387.
Fetch the next digit (7) from the dividend, attach it to 387 and continue: 3877 / 509

On to step 5:
509 can be fit into 3877 7 times, resulting in a remainder of 314.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtract 3563 from 3877 to get 314.
Fetch the next digit (8) from the dividend, attach it to 314 and continue: 3148 / 509

Moving on to step 6:
509 goes into 3148 6 times with a remainder of 94.
The number 6 becomes the next digit in our result. 
Result so far: 976.0
Subtract 3054 from 3148 to get 94.
Grab the next digit (1) from the dividend, add it to 94, then carry on: 941 / 509

Going ahead to step 7:
When dividing 941 by 509, we get 1 with a remainder of 432.
Write down 1 as next digit of the result. 
Result so far: 9761.0
Deduct 509 from 941 and we're left with 432.
Grab the next digit (0) from the dividend, add it to 432, then carry on: 4320 / 509

On to step 8:
509 can be fit into 4320 8 times, resulting in a remainder of 248.
Record the quotient 8 as the next digit in the result. 
Result so far: 97618.0
Subtract 4072 from 4320 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 9:
509 can be fit into 2480 4 times, resulting in a remainder of 444.
Put 4 as the next digit of the answer. 
Result so far: 97618.4
If we take 2036 away from 2480, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 10:
If we divide 4440 by 509, we get 8 and a remainder of 368.
The next digit of our result is 8. 
Result so far: 97618.48
The remainder is 368 after subtracting 4072 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 11:
The number 509 fits into 3680 7 times, leaving a remainder of 117.
The next digit of our result is 7. 
Result so far: 97618.487
If we take 3563 away from 3680, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 12:
509 can be fit into 1170 2 times, resulting in a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 97618.4872
The remainder is 152 after subtracting 1018 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 13:
1520 divided by 509 is 2 with a remainder of 502.
The next digit of our result is 2. 
Result so far: 97618.48722
If we take 1018 away from 1520, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

The final outcome is 97618.48722, with a leftover of 0.000502.
