915237 divided by 3 
The aim is to understand the frequency of 3 in 915237.

Advancing to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 9 from 9 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Step 2:
When dividing 1 by 3, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 30.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Advancing to step 3:
3 can be fit into 15 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 305.0
If we take 15 away from 15, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Going ahead to step 4:
When dividing 2 by 3, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 3050.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Moving on to step 5:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 30507.0
Subtracting 21 from 23 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 3

Step 6:
When dividing 27 by 3, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 305079.0
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.

On to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 305079.0
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.

Advancing to step 8:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 305079.0
Deduct 0 from 0 and we're left 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.

Our division results in 305079.0 with a remaining 0.0.
