51735838 ÷ 15 
We want to figure out the number of times 51735838 can be divided by 15.

On to step 1:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 15

Let's proceed to step 2:
51 divided by 15 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 45 away from 51, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 15

Let's proceed to step 3:
When dividing 67 by 15, we get 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtracting 60 from 67 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 15

Moving on to step 4:
If we divide 73 by 15, we get 4 and a remainder of 13.
The next digit of our result is 4. 
Result so far: 344.0
Subtracting 60 from 73 leaves us with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 15

Going ahead to step 5:
15 goes into 135 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 3449.0
If we take 135 away from 135, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 15

Going ahead to step 6:
If we divide 8 by 15, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 34490.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 15

Moving on to step 7:
When dividing 83 by 15, we get 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 344905.0
If we subtract 75 from 83, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 15

On to step 8:
If we divide 88 by 15, we get 5 and a remainder of 13.
The next digit of our result is 5. 
Result so far: 3449055.0
Subtracting 75 from 88 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
When dividing 130 by 15, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 3449055.8
Deduct 120 from 130 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 3449055.86
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
When dividing 100 by 15, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 3449055.866
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 3449055.866, with a leftover of 0.001.
