13398087 ÷ 750 
Our goal is to divide 13398087 by 750.

Going ahead to step 1:
When dividing 1 by 750, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 750

On to step 2:
750 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 750

Step 3:
The number 750 fits into 133 0 times, leaving a remainder of 133.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 133, we end up with 133.
Fetch the next digit (9) from the dividend, attach it to 133 and continue: 1339 / 750

Going ahead to step 4:
The number 750 fits into 1339 1 times, leaving a remainder of 589.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 750 from 1339 and we're left with 589.
Include the next digit (8) from the dividend after 589, then repeat: 5898 / 750

Let's proceed to step 5:
750 goes into 5898 7 times with a remainder of 648.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 648 after subtracting 5250 from 5898.
Include the next digit (0) from the dividend after 648, then repeat: 6480 / 750

Advancing to step 6:
750 can be fit into 6480 8 times, resulting in a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 178.0
The remainder is 480 after subtracting 6000 from 6480.
Grab the next digit (8) from the dividend, add it to 480, then carry on: 4808 / 750

Let's proceed to step 7:
When dividing 4808 by 750, we get 6 with a remainder of 308.
Record the quotient 6 as the next digit in the result. 
Result so far: 1786.0
If we take 4500 away from 4808, we end up with 308.
Bring next digit (7) of the dividend behind the 308 and repeat the process: 3087 / 750

Going ahead to step 8:
750 goes into 3087 4 times with a remainder of 87.
The number 4 becomes the next digit in our result. 
Result so far: 17864.0
If we subtract 3000 from 3087, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 9:
The number 750 fits into 870 1 times, leaving a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 17864.1
Subtract 750 from 870 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
750 goes into 1200 1 times with a remainder of 450.
Write down 1 as next digit of the result. 
Result so far: 17864.11
The remainder is 450 after subtracting 750 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

The quotient of the division is 17864.11, and the remainder is 0.45.
