18620217 ÷ 513 
We want to figure out the number of times 18620217 can be divided by 513.

On to step 1:
When dividing 1 by 513, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 513

Let's proceed to step 2:
The number 513 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 513

Let's proceed to step 3:
The number 513 fits into 186 0 times, leaving a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 186 after subtracting 0 from 186.
Append the next digit (2) from the dividend to 186 and continue with: 1862 / 513

Going ahead to step 4:
513 goes into 1862 3 times with a remainder of 323.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1539 from 1862 leaves us with 323.
Append the next digit (0) from the dividend to 323 and continue with: 3230 / 513

On to step 5:
513 goes into 3230 6 times with a remainder of 152.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 3078 from 3230 and we're left with 152.
Fetch the next digit (2) from the dividend, attach it to 152 and continue: 1522 / 513

Going ahead to step 6:
If we divide 1522 by 513, we get 2 and a remainder of 496.
Put 2 as the next digit of the answer. 
Result so far: 362.0
If we take 1026 away from 1522, we end up with 496.
Bring next digit (1) of the dividend behind the 496 and repeat the process: 4961 / 513

Moving on to step 7:
If we divide 4961 by 513, we get 9 and a remainder of 344.
Write down 9 as next digit of the result. 
Result so far: 3629.0
The remainder is 344 after subtracting 4617 from 4961.
Take the next digit (7) from the dividend and append it to 344, then repeat: 3447 / 513

On to step 8:
If we divide 3447 by 513, we get 6 and a remainder of 369.
Use 6 as the next digit of our solution. 
Result so far: 36296.0
If we subtract 3078 from 3447, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Advancing to step 9:
513 goes into 3690 7 times with a remainder of 99.
Record the quotient 7 as the next digit in the result. 
Result so far: 36296.7
If we subtract 3591 from 3690, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 10:
The number 513 fits into 990 1 times, leaving a remainder of 477.
The next digit of our result is 1. 
Result so far: 36296.71
Deduct 513 from 990 and we're left with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Let's proceed to step 11:
4770 divided by 513 is 9 with a remainder of 153.
Write down 9 as next digit of the result. 
Result so far: 36296.719
Subtract 4617 from 4770 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 12:
513 goes into 1530 2 times with a remainder of 504.
Use 2 as the next digit of our solution. 
Result so far: 36296.7192
If we take 1026 away from 1530, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 13:
If we divide 5040 by 513, we get 9 and a remainder of 423.
Write down 9 as next digit of the result. 
Result so far: 36296.71929
The remainder is 423 after subtracting 4617 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Let's proceed to step 14:
The number 513 fits into 4230 8 times, leaving a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 36296.719298
If we take 4104 away from 4230, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 15:
1260 divided by 513 is 2 with a remainder of 234.
Put 2 as the next digit of the answer. 
Result so far: 36296.7192982
Subtracting 1026 from 1260 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 16:
513 can be fit into 2340 4 times, resulting in a remainder of 288.
Write down 4 as next digit of the result. 
Result so far: 36296.71929824
If we take 2052 away from 2340, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Our division results in 36296.71929824 with a remaining 2.88e-07.
