We divide 31312715 by 702
The aim is to understand the frequency of 702 in 31312715.

Moving on to step 1:
3 divided by 702 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 702

Moving on to step 2:
When dividing 31 by 702, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 702

On to step 3:
702 goes into 313 0 times with a remainder of 313.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 313, we get 313.
Include the next digit (1) from the dividend after 313, then repeat: 3131 / 702

Step 4:
When dividing 3131 by 702, we get 4 with a remainder of 323.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2808 from 3131 to get 323.
Append the next digit (2) from the dividend to 323 and continue with: 3232 / 702

On to step 5:
702 can be fit into 3232 4 times, resulting in a remainder of 424.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 2808 from 3232, we get 424.
Append the next digit (7) from the dividend to 424 and continue with: 4247 / 702

Advancing to step 6:
When dividing 4247 by 702, we get 6 with a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 446.0
If we take 4212 away from 4247, we end up with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 702

Let's proceed to step 7:
702 can be fit into 351 0 times, resulting in a remainder of 351.
Use 0 as the next digit of our solution. 
Result so far: 4460.0
If we take 0 away from 351, we end up with 351.
Bring next digit (5) of the dividend behind the 351 and repeat the process: 3515 / 702

On to step 8:
If we divide 3515 by 702, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 44605.0
Deduct 3510 from 3515 and we're left 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.

Going ahead to step 9:
If we divide 50 by 702, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 44605.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
When dividing 500 by 702, we get 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 44605.0
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 44605.0 and a remainder of 0.5.
