78085498 ÷ 518 
Our goal is to divide 78085498 by 518.

Going ahead to step 1:
7 divided by 518 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 518

On to step 2:
If we divide 78 by 518, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 518

Moving on to step 3:
If we divide 780 by 518, we get 1 and a remainder of 262.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 518 from 780 and we're left with 262.
Grab the next digit (8) from the dividend, add it to 262, then carry on: 2628 / 518

On to step 4:
When dividing 2628 by 518, we get 5 with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2590 away from 2628, we end up with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 518

On to step 5:
When dividing 385 by 518, we get 0 with a remainder of 385.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Deduct 0 from 385 and we're left with 385.
Bring next digit (4) of the dividend behind the 385 and repeat the process: 3854 / 518

Let's proceed to step 6:
If we divide 3854 by 518, we get 7 and a remainder of 228.
Record the quotient 7 as the next digit in the result. 
Result so far: 1507.0
The remainder is 228 after subtracting 3626 from 3854.
Append the next digit (9) from the dividend to 228 and continue with: 2289 / 518

On to step 7:
If we divide 2289 by 518, we get 4 and a remainder of 217.
Use 4 as the next digit of our solution. 
Result so far: 15074.0
Subtracting 2072 from 2289 leaves us with 217.
Grab the next digit (8) from the dividend, add it to 217, then carry on: 2178 / 518

Going ahead to step 8:
2178 divided by 518 is 4 with a remainder of 106.
Use 4 as the next digit of our solution. 
Result so far: 150744.0
If we take 2072 away from 2178, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 9:
518 goes into 1060 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 150744.2
Deduct 1036 from 1060 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
518 goes into 240 0 times with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 150744.2
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
518 can be fit into 2400 4 times, resulting in a remainder of 328.
Write down 4 as next digit of the result. 
Result so far: 150744.204
If we subtract 2072 from 2400, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 12:
The number 518 fits into 3280 6 times, leaving a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 150744.2046
Subtracting 3108 from 3280 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 13:
518 can be fit into 1720 3 times, resulting in a remainder of 166.
The next digit of our result is 3. 
Result so far: 150744.20463
If we subtract 1554 from 1720, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 14:
The number 518 fits into 1660 3 times, leaving a remainder of 106.
Record the quotient 3 as the next digit in the result. 
Result so far: 150744.204633
Deduct 1554 from 1660 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

After the division, we end up with 150744.204633 and a remainder of 1.06e-05.
