We divide 771631 by 15
Let's see how many times 15 fits into 771631.

On to step 1:
7 divided by 15 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 15

Going ahead to step 2:
If we divide 77 by 15, we get 5 and a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 75 from 77 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 15

Advancing to step 3:
15 can be fit into 21 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we take 15 away from 21, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 15

Let's proceed to step 4:
The number 15 fits into 66 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 514.0
Subtracting 60 from 66 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 15

Moving on to step 5:
63 divided by 15 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 5144.0
If we subtract 60 from 63, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 15

Let's proceed to step 6:
If we divide 31 by 15, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 51442.0
Subtract 30 from 31 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 15 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 51442.0
Subtract 0 from 10 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 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 51442.06
Deduct 90 from 100 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.

Let's proceed to step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 51442.066
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.

Our division results in 51442.066 with a remaining 0.001.
