Let's divide 1665585 by 518
Let's see how many times 518 fits into 1665585.

Let's proceed to step 1:
The number 518 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 518

Advancing to step 2:
When dividing 16 by 518, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 518

Let's proceed to step 3:
The number 518 fits into 166 0 times, leaving a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 166, we get 166.
Append the next digit (5) from the dividend to 166 and continue with: 1665 / 518

On to step 4:
The number 518 fits into 1665 3 times, leaving a remainder of 111.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 1554 from 1665 leaves us with 111.
Fetch the next digit (5) from the dividend, attach it to 111 and continue: 1115 / 518

Let's proceed to step 5:
The number 518 fits into 1115 2 times, leaving a remainder of 79.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 1036 from 1115 to get 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 518

Step 6:
When dividing 798 by 518, we get 1 with a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 321.0
Deduct 518 from 798 and we're left with 280.
Take the next digit (5) from the dividend and append it to 280, then repeat: 2805 / 518

On to step 7:
If we divide 2805 by 518, we get 5 and a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 3215.0
Subtracting 2590 from 2805 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 8:
2150 divided by 518 is 4 with a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 3215.4
The remainder is 78 after subtracting 2072 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
518 goes into 780 1 times with a remainder of 262.
Put 1 as the next digit of the answer. 
Result so far: 3215.41
If we subtract 518 from 780, we get 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 10:
The number 518 fits into 2620 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3215.415
Subtracting 2590 from 2620 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
300 divided by 518 is 0 with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 3215.415
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 12:
If we divide 3000 by 518, we get 5 and a remainder of 410.
Put 5 as the next digit of the answer. 
Result so far: 3215.41505
Deduct 2590 from 3000 and we're left 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.

Step 13:
If we divide 4100 by 518, we get 7 and a remainder of 474.
The next digit of our result is 7. 
Result so far: 3215.415057
The remainder is 474 after subtracting 3626 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 14:
If we divide 4740 by 518, we get 9 and a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 3215.4150579
If we take 4662 away from 4740, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 15:
If we divide 780 by 518, we get 1 and a remainder of 262.
Use 1 as the next digit of our solution. 
Result so far: 3215.41505791
Subtract 518 from 780 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

The final outcome is 3215.41505791, with a leftover of 2.62e-07.
