We're dividing 641265 by 15 
Let's see how many times 15 fits into 641265.

Going ahead to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 15

Going ahead to step 2:
15 can be fit into 64 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 60 from 64, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 15

Advancing to step 3:
If we divide 41 by 15, we get 2 and a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 30 away from 41, we end up with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 15

Let's proceed to step 4:
If we divide 112 by 15, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 427.0
Deduct 105 from 112 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 15

On to step 5:
If we divide 76 by 15, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 4275.0
If we subtract 75 from 76, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 15

Let's proceed to step 6:
When dividing 15 by 15, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 42751.0
Subtract 15 from 15 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 15 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42751.0
Deduct 0 from 0 and we're left 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.

Step 8:
0 divided by 15 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42751.0
If we take 0 away from 0, we end up 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.

The final outcome is 42751.0, with a leftover of 0.0.
