71439515 divided by 702 
The aim is to understand the frequency of 702 in 71439515.

On to step 1:
7 divided by 702 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 702

Step 2:
702 can be fit into 71 0 times, resulting in a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 702

On to step 3:
702 can be fit into 714 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 702 from 714 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 702

Going ahead to step 4:
When dividing 123 by 702, we get 0 with a remainder of 123.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 123, we get 123.
Append the next digit (9) from the dividend to 123 and continue with: 1239 / 702

On to step 5:
If we divide 1239 by 702, we get 1 and a remainder of 537.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtracting 702 from 1239 leaves us with 537.
Take the next digit (5) from the dividend and append it to 537, then repeat: 5375 / 702

Going ahead to step 6:
If we divide 5375 by 702, we get 7 and a remainder of 461.
The next digit of our result is 7. 
Result so far: 1017.0
Subtracting 4914 from 5375 leaves us with 461.
Bring next digit (1) of the dividend behind the 461 and repeat the process: 4611 / 702

Going ahead to step 7:
702 goes into 4611 6 times with a remainder of 399.
Put 6 as the next digit of the answer. 
Result so far: 10176.0
Subtract 4212 from 4611 to get 399.
Bring next digit (5) of the dividend behind the 399 and repeat the process: 3995 / 702

Advancing to step 8:
If we divide 3995 by 702, we get 5 and a remainder of 485.
Record the quotient 5 as the next digit in the result. 
Result so far: 101765.0
Subtracting 3510 from 3995 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 9:
702 goes into 4850 6 times with a remainder of 638.
Write down 6 as next digit of the result. 
Result so far: 101765.6
If we subtract 4212 from 4850, we get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Going ahead to step 10:
702 can be fit into 6380 9 times, resulting in a remainder of 62.
The next digit of our result is 9. 
Result so far: 101765.69
If we subtract 6318 from 6380, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
620 divided by 702 is 0 with a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 101765.69
If we take 0 away from 620, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 12:
When dividing 6200 by 702, we get 8 with a remainder of 584.
The number 8 becomes the next digit in our result. 
Result so far: 101765.6908
If we take 5616 away from 6200, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 13:
5840 divided by 702 is 8 with a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 101765.69088
Deduct 5616 from 5840 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 101765.69088 with a remainder of 0.000224.
