We divide 77101390 by 15
Let's see how many times 15 fits into 77101390.

Moving on to step 1:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 15

Going ahead to step 2:
When dividing 77 by 15, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 75 from 77 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 15

Step 3:
21 divided by 15 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we take 15 away from 21, we end up with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 15

On to step 4:
15 goes into 60 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 514.0
If we take 60 away from 60, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 15

Advancing to step 5:
When dividing 1 by 15, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 5140.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 15

Step 6:
13 divided by 15 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 51400.0
Subtract 0 from 13 to get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 15

Moving on to step 7:
If we divide 139 by 15, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 514009.0
Subtract 135 from 139 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 15

Step 8:
The number 15 fits into 40 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 5140092.0
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.

Going ahead to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 5140092.6
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.

Going ahead to step 10:
100 divided by 15 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 5140092.66
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 5140092.66 with a remaining 0.01.
