Let's divide 7631378 by 518
We want to divide 7631378 by 518.

On to step 1:
When dividing 7 by 518, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 518

On to step 2:
If we divide 76 by 518, we get 0 and a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 518

Advancing to step 3:
763 divided by 518 is 1 with a remainder of 245.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 518 from 763 leaves us with 245.
Bring next digit (1) of the dividend behind the 245 and repeat the process: 2451 / 518

Moving on to step 4:
If we divide 2451 by 518, we get 4 and a remainder of 379.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 379 after subtracting 2072 from 2451.
Bring next digit (3) of the dividend behind the 379 and repeat the process: 3793 / 518

Step 5:
If we divide 3793 by 518, we get 7 and a remainder of 167.
The next digit of our result is 7. 
Result so far: 147.0
Deduct 3626 from 3793 and we're left with 167.
Take the next digit (7) from the dividend and append it to 167, then repeat: 1677 / 518

Step 6:
When dividing 1677 by 518, we get 3 with a remainder of 123.
Record the quotient 3 as the next digit in the result. 
Result so far: 1473.0
Subtract 1554 from 1677 to get 123.
Take the next digit (8) from the dividend and append it to 123, then repeat: 1238 / 518

Going ahead to step 7:
If we divide 1238 by 518, we get 2 and a remainder of 202.
The number 2 becomes the next digit in our result. 
Result so far: 14732.0
Subtract 1036 from 1238 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 8:
If we divide 2020 by 518, we get 3 and a remainder of 466.
The next digit of our result is 3. 
Result so far: 14732.3
Subtract 1554 from 2020 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 9:
4660 divided by 518 is 8 with a remainder of 516.
Write down 8 as next digit of the result. 
Result so far: 14732.38
If we subtract 4144 from 4660, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 10:
5160 divided by 518 is 9 with a remainder of 498.
Write down 9 as next digit of the result. 
Result so far: 14732.389
If we take 4662 away from 5160, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 11:
4980 divided by 518 is 9 with a remainder of 318.
Use 9 as the next digit of our solution. 
Result so far: 14732.3899
Deduct 4662 from 4980 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

The final result is 14732.3899 with a remainder of 0.00318.
