We want to divide 43660599 by 515.

On to step 1:
The number 515 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 515

On to step 2:
When dividing 43 by 515, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 515

Let's proceed to step 3:
436 divided by 515 is 0 with a remainder of 436.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 436, we get 436.
Include the next digit (6) from the dividend after 436, then repeat: 4366 / 515

Going ahead to step 4:
When dividing 4366 by 515, we get 8 with a remainder of 246.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 4120 from 4366, we get 246.
Take the next digit (0) from the dividend and append it to 246, then repeat: 2460 / 515

Going ahead to step 5:
2460 divided by 515 is 4 with a remainder of 400.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Deduct 2060 from 2460 and we're left with 400.
Append the next digit (5) from the dividend to 400 and continue with: 4005 / 515

Moving on to step 6:
4005 divided by 515 is 7 with a remainder of 400.
Use 7 as the next digit of our solution. 
Result so far: 847.0
Subtracting 3605 from 4005 leaves us with 400.
Fetch the next digit (9) from the dividend, attach it to 400 and continue: 4009 / 515

Going ahead to step 7:
When dividing 4009 by 515, we get 7 with a remainder of 404.
The next digit of our result is 7. 
Result so far: 8477.0
Deduct 3605 from 4009 and we're left with 404.
Take the next digit (9) from the dividend and append it to 404, then repeat: 4049 / 515

Going ahead to step 8:
The number 515 fits into 4049 7 times, leaving a remainder of 444.
The number 7 becomes the next digit in our result. 
Result so far: 84777.0
Subtract 3605 from 4049 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 9:
4440 divided by 515 is 8 with a remainder of 320.
The number 8 becomes the next digit in our result. 
Result so far: 84777.8
If we take 4120 away from 4440, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
515 can be fit into 3200 6 times, resulting in a remainder of 110.
Use 6 as the next digit of our solution. 
Result so far: 84777.86
If we subtract 3090 from 3200, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 11:
If we divide 1100 by 515, we get 2 and a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 84777.862
If we subtract 1030 from 1100, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
515 can be fit into 700 1 times, resulting in a remainder of 185.
Record the quotient 1 as the next digit in the result. 
Result so far: 84777.8621
Deduct 515 from 700 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 13:
If we divide 1850 by 515, we get 3 and a remainder of 305.
Put 3 as the next digit of the answer. 
Result so far: 84777.86213
If we subtract 1545 from 1850, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 14:
If we divide 3050 by 515, we get 5 and a remainder of 475.
Record the quotient 5 as the next digit in the result. 
Result so far: 84777.862135
If we subtract 2575 from 3050, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Advancing to step 15:
515 goes into 4750 9 times with a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 84777.8621359
Subtracting 4635 from 4750 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 16:
515 can be fit into 1150 2 times, resulting in a remainder of 120.
The next digit of our result is 2. 
Result so far: 84777.86213592
Deduct 1030 from 1150 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 84777.86213592 with a balance of 1.2e-07.
