338310 ÷ 28 
We want to figure out the number of times 338310 can be divided by 28.

On to step 1:
3 divided by 28 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 28

Moving on to step 2:
If we divide 33 by 28, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 5 after subtracting 28 from 33.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 28

Advancing to step 3:
The number 28 fits into 58 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 56 from 58 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 28

Advancing to step 4:
28 can be fit into 23 0 times, resulting in a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 28

Moving on to step 5:
If we divide 231 by 28, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 1208.0
Deduct 224 from 231 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 28

Moving on to step 6:
28 goes into 70 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 12082.0
Subtracting 56 from 70 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
The number 28 fits into 140 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12082.5
If we take 140 away from 140, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 28 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12082.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 28, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12082.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 12082.5, with a leftover of 0.0.
