5464399 ÷ 15 
We want to divide 5464399 by 15.

Going ahead to step 1:
15 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 15

Moving on to step 2:
15 can be fit into 54 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
If we take 45 away from 54, we end up with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 15

Going ahead to step 3:
96 divided by 15 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 36.0
If we take 90 away from 96, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 15

Moving on to step 4:
15 can be fit into 64 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 364.0
If we subtract 60 from 64, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 15

Let's proceed to step 5:
When dividing 43 by 15, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 3642.0
Deduct 30 from 43 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 15

Let's proceed to step 6:
15 goes into 139 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 36429.0
Subtracting 135 from 139 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 15

Let's proceed to step 7:
When dividing 49 by 15, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 364293.0
Deduct 45 from 49 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 15 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 364293.2
If we take 30 away from 40, we end up 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 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 364293.26
If we take 90 away from 100, we end up 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:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 364293.266
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 364293.266 with a remaining 0.001.
