We look at the division of 71718413 by 516 
The aim is to understand the frequency of 516 in 71718413.

Advancing to step 1:
516 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 516

Advancing to step 2:
The number 516 fits into 71 0 times, leaving a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 516

Going ahead to step 3:
516 goes into 717 1 times with a remainder of 201.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 516 from 717 to get 201.
Take the next digit (1) from the dividend and append it to 201, then repeat: 2011 / 516

Advancing to step 4:
516 goes into 2011 3 times with a remainder of 463.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 463 after subtracting 1548 from 2011.
Fetch the next digit (8) from the dividend, attach it to 463 and continue: 4638 / 516

Going ahead to step 5:
516 goes into 4638 8 times with a remainder of 510.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtract 4128 from 4638 to get 510.
Append the next digit (4) from the dividend to 510 and continue with: 5104 / 516

Going ahead to step 6:
The number 516 fits into 5104 9 times, leaving a remainder of 460.
Record the quotient 9 as the next digit in the result. 
Result so far: 1389.0
Subtracting 4644 from 5104 leaves us with 460.
Grab the next digit (1) from the dividend, add it to 460, then carry on: 4601 / 516

Step 7:
When dividing 4601 by 516, we get 8 with a remainder of 473.
Use 8 as the next digit of our solution. 
Result so far: 13898.0
Deduct 4128 from 4601 and we're left with 473.
Grab the next digit (3) from the dividend, add it to 473, then carry on: 4733 / 516

Moving on to step 8:
4733 divided by 516 is 9 with a remainder of 89.
Write down 9 as next digit of the result. 
Result so far: 138989.0
If we take 4644 away from 4733, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 9:
If we divide 890 by 516, we get 1 and a remainder of 374.
Put 1 as the next digit of the answer. 
Result so far: 138989.1
Deduct 516 from 890 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 10:
516 can be fit into 3740 7 times, resulting in a remainder of 128.
Put 7 as the next digit of the answer. 
Result so far: 138989.17
If we take 3612 away from 3740, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 11:
The number 516 fits into 1280 2 times, leaving a remainder of 248.
Record the quotient 2 as the next digit in the result. 
Result so far: 138989.172
The remainder is 248 after subtracting 1032 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 12:
2480 divided by 516 is 4 with a remainder of 416.
The number 4 becomes the next digit in our result. 
Result so far: 138989.1724
Deduct 2064 from 2480 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 13:
4160 divided by 516 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 138989.17248
If we subtract 4128 from 4160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
516 goes into 320 0 times with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 138989.17248
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
3200 divided by 516 is 6 with a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 138989.1724806
Subtract 3096 from 3200 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 16:
516 can be fit into 1040 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 138989.17248062
Deduct 1032 from 1040 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 138989.17248062 with a remainder of 8e-09.
