915177 divided by 3 
We want to figure out the number of times 915177 can be divided by 3.

Step 1:
3 goes into 9 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 9 away from 9, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Going ahead to step 2:
3 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Moving on to step 3:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 305.0
Subtracting 15 from 15 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

Advancing to step 4:
When dividing 1 by 3, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 3050.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 3

Advancing to step 5:
The number 3 fits into 17 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 30505.0
Deduct 15 from 17 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 3

Step 6:
If we divide 27 by 3, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 305059.0
If we take 27 away from 27, 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.

Moving on to step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 305059.0
Subtract 0 from 0 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.

On to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 305059.0
If we subtract 0 from 0, we 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.

The final outcome is 305059.0, with a leftover of 0.0.
