We look at the division of 91735219 by 15 
Our goal is to divide 91735219 by 15.

Let's proceed to step 1:
The number 15 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 15

Going ahead to step 2:
15 can be fit into 91 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 90 from 91, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 15

Moving on to step 3:
When dividing 17 by 15, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
Deduct 15 from 17 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 15

Step 4:
15 goes into 23 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 611.0
Deduct 15 from 23 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 15

Going ahead to step 5:
15 can be fit into 85 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 6115.0
If we subtract 75 from 85, we get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 15

On to step 6:
102 divided by 15 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 61156.0
Deduct 90 from 102 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 15

Let's proceed to step 7:
15 goes into 121 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 611568.0
If we take 120 away from 121, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 15

On to step 8:
19 divided by 15 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 6115681.0
If we subtract 15 from 19, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
15 can be fit into 40 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 6115681.2
Deduct 30 from 40 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.

Moving on to step 10:
When dividing 100 by 15, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 6115681.26
If we subtract 90 from 100, we 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.

Advancing to step 11:
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: 6115681.266
Subtracting 90 from 100 leaves us 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.

The final result is 6115681.266 with a remainder of 0.001.
