Let's divide 15338791 by 516
We're looking to find how many times 516 goes into 15338791.

On to step 1:
1 divided by 516 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 516

Moving on to step 2:
516 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 516

Moving on to step 3:
If we divide 153 by 516, we get 0 and a remainder of 153.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 153 and we're left with 153.
Grab the next digit (3) from the dividend, add it to 153, then carry on: 1533 / 516

Going ahead to step 4:
If we divide 1533 by 516, we get 2 and a remainder of 501.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1032 from 1533, we get 501.
Append the next digit (8) from the dividend to 501 and continue with: 5018 / 516

Advancing to step 5:
The number 516 fits into 5018 9 times, leaving a remainder of 374.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 4644 from 5018 leaves us with 374.
Take the next digit (7) from the dividend and append it to 374, then repeat: 3747 / 516

Step 6:
If we divide 3747 by 516, we get 7 and a remainder of 135.
The next digit of our result is 7. 
Result so far: 297.0
Subtracting 3612 from 3747 leaves us with 135.
Fetch the next digit (9) from the dividend, attach it to 135 and continue: 1359 / 516

Going ahead to step 7:
If we divide 1359 by 516, we get 2 and a remainder of 327.
Record the quotient 2 as the next digit in the result. 
Result so far: 2972.0
Subtract 1032 from 1359 to get 327.
Bring next digit (1) of the dividend behind the 327 and repeat the process: 3271 / 516

Going ahead to step 8:
516 can be fit into 3271 6 times, resulting in a remainder of 175.
Put 6 as the next digit of the answer. 
Result so far: 29726.0
The remainder is 175 after subtracting 3096 from 3271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 9:
1750 divided by 516 is 3 with a remainder of 202.
Use 3 as the next digit of our solution. 
Result so far: 29726.3
Deduct 1548 from 1750 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 10:
The number 516 fits into 2020 3 times, leaving a remainder of 472.
Record the quotient 3 as the next digit in the result. 
Result so far: 29726.33
Subtracting 1548 from 2020 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

After the division, we end up with 29726.33 and a remainder of 0.472.
