39577888 ÷ 518 
Our goal is to divide 39577888 by 518.

Let's proceed to step 1:
If we divide 3 by 518, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 518

Let's proceed to step 2:
518 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 518

Moving on to step 3:
518 goes into 395 0 times with a remainder of 395.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 395, we get 395.
Include the next digit (7) from the dividend after 395, then repeat: 3957 / 518

Moving on to step 4:
3957 divided by 518 is 7 with a remainder of 331.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 3626 from 3957 and we're left with 331.
Append the next digit (7) from the dividend to 331 and continue with: 3317 / 518

Let's proceed to step 5:
When dividing 3317 by 518, we get 6 with a remainder of 209.
Use 6 as the next digit of our solution. 
Result so far: 76.0
If we subtract 3108 from 3317, we get 209.
Grab the next digit (8) from the dividend, add it to 209, then carry on: 2098 / 518

On to step 6:
If we divide 2098 by 518, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 764.0
If we take 2072 away from 2098, we end up with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 518

Going ahead to step 7:
518 goes into 268 0 times with a remainder of 268.
Write down 0 as next digit of the result. 
Result so far: 7640.0
If we subtract 0 from 268, we get 268.
Append the next digit (8) from the dividend to 268 and continue with: 2688 / 518

On to step 8:
If we divide 2688 by 518, we get 5 and a remainder of 98.
Write down 5 as next digit of the result. 
Result so far: 76405.0
Subtract 2590 from 2688 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 9:
The number 518 fits into 980 1 times, leaving a remainder of 462.
The next digit of our result is 1. 
Result so far: 76405.1
The remainder is 462 after subtracting 518 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 10:
4620 divided by 518 is 8 with a remainder of 476.
Record the quotient 8 as the next digit in the result. 
Result so far: 76405.18
If we take 4144 away from 4620, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 11:
The number 518 fits into 4760 9 times, leaving a remainder of 98.
Use 9 as the next digit of our solution. 
Result so far: 76405.189
Subtract 4662 from 4760 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 12:
980 divided by 518 is 1 with a remainder of 462.
Write down 1 as next digit of the result. 
Result so far: 76405.1891
Deduct 518 from 980 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Let's proceed to step 13:
The number 518 fits into 4620 8 times, leaving a remainder of 476.
The next digit of our result is 8. 
Result so far: 76405.18918
If we take 4144 away from 4620, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 14:
518 can be fit into 4760 9 times, resulting in a remainder of 98.
Put 9 as the next digit of the answer. 
Result so far: 76405.189189
Subtracting 4662 from 4760 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 15:
980 divided by 518 is 1 with a remainder of 462.
Record the quotient 1 as the next digit in the result. 
Result so far: 76405.1891891
Subtract 518 from 980 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 16:
If we divide 4620 by 518, we get 8 and a remainder of 476.
The number 8 becomes the next digit in our result. 
Result so far: 76405.18918918
Subtract 4144 from 4620 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The final outcome is 76405.18918918, with a leftover of 4.76e-07.
