We look at the division of 53434968 by 15 
We want to figure out the number of times 53434968 can be divided by 15.

Going ahead to step 1:
When dividing 5 by 15, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 15

Moving on to step 2:
53 divided by 15 is 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
If we take 45 away from 53, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 15

Moving on to step 3:
15 goes into 84 5 times with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 75 from 84, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 15

Step 4:
93 divided by 15 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 356.0
If we take 90 away from 93, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 15

Going ahead to step 5:
34 divided by 15 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3562.0
Subtracting 30 from 34 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 15

On to step 6:
If we divide 49 by 15, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 35623.0
The remainder is 4 after subtracting 45 from 49.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 15

Moving on to step 7:
15 goes into 46 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 356233.0
If we take 45 away from 46, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 15

Step 8:
18 divided by 15 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 3562331.0
If we subtract 15 from 18, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
15 goes into 30 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 3562331.2
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
0 divided by 15 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3562331.2
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 11:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3562331.2
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 3562331.2, with a leftover of 0.0.
