We look at the division of 752921 by 15 
We want to figure out the number of times 752921 can be divided by 15.

Let's proceed to step 1:
15 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 15

Going ahead to step 2:
15 can be fit into 75 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 75 from 75 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 15

Let's proceed to step 3:
2 divided by 15 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we take 0 away from 2, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 15

Going ahead to step 4:
If we divide 29 by 15, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 501.0
Deduct 15 from 29 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 15

Step 5:
15 goes into 142 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 5019.0
Subtract 135 from 142 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 15

Moving on to step 6:
If we divide 71 by 15, we get 4 and a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 50194.0
Deduct 60 from 71 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 15 fits into 110 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 50194.7
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 50194.73
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 50194.733
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 50194.733, and the remainder is 0.0005.
