We divide 358091 by 15
We want to figure out the number of times 358091 can be divided by 15.

Step 1:
15 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 15

Advancing to step 2:
35 divided by 15 is 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 30 from 35 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 15

Advancing to step 3:
15 can be fit into 58 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 45 from 58 to get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 15

Going ahead to step 4:
If we divide 130 by 15, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
Deduct 120 from 130 and we're left with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 15

Going ahead to step 5:
If we divide 109 by 15, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 2387.0
Deduct 105 from 109 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 15

Going ahead to step 6:
15 goes into 41 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 23872.0
Deduct 30 from 41 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 15 fits into 110 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 23872.7
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 23872.73
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 23872.733
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 23872.733 with a remaining 0.0005.
