99771449 ÷ 516 
The aim is to understand the frequency of 516 in 99771449.

Advancing to step 1:
516 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 516

On to step 2:
The number 516 fits into 99 0 times, leaving a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Append the next digit (7) from the dividend to 99 and continue with: 997 / 516

Step 3:
When dividing 997 by 516, we get 1 with a remainder of 481.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 516 from 997 leaves us with 481.
Grab the next digit (7) from the dividend, add it to 481, then carry on: 4817 / 516

Moving on to step 4:
4817 divided by 516 is 9 with a remainder of 173.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 4644 from 4817, we get 173.
Include the next digit (1) from the dividend after 173, then repeat: 1731 / 516

Going ahead to step 5:
516 goes into 1731 3 times with a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 193.0
If we subtract 1548 from 1731, we get 183.
Include the next digit (4) from the dividend after 183, then repeat: 1834 / 516

Let's proceed to step 6:
If we divide 1834 by 516, we get 3 and a remainder of 286.
The number 3 becomes the next digit in our result. 
Result so far: 1933.0
Subtracting 1548 from 1834 leaves us with 286.
Fetch the next digit (4) from the dividend, attach it to 286 and continue: 2864 / 516

Advancing to step 7:
2864 divided by 516 is 5 with a remainder of 284.
Record the quotient 5 as the next digit in the result. 
Result so far: 19335.0
Deduct 2580 from 2864 and we're left with 284.
Include the next digit (9) from the dividend after 284, then repeat: 2849 / 516

Let's proceed to step 8:
2849 divided by 516 is 5 with a remainder of 269.
The number 5 becomes the next digit in our result. 
Result so far: 193355.0
Subtracting 2580 from 2849 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 9:
516 goes into 2690 5 times with a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 193355.5
If we take 2580 away from 2690, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
1100 divided by 516 is 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 193355.52
If we subtract 1032 from 1100, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
680 divided by 516 is 1 with a remainder of 164.
The number 1 becomes the next digit in our result. 
Result so far: 193355.521
If we take 516 away from 680, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 12:
When dividing 1640 by 516, we get 3 with a remainder of 92.
Use 3 as the next digit of our solution. 
Result so far: 193355.5213
The remainder is 92 after subtracting 1548 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 13:
920 divided by 516 is 1 with a remainder of 404.
The next digit of our result is 1. 
Result so far: 193355.52131
Subtract 516 from 920 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 14:
If we divide 4040 by 516, we get 7 and a remainder of 428.
The next digit of our result is 7. 
Result so far: 193355.521317
Subtracting 3612 from 4040 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 15:
4280 divided by 516 is 8 with a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 193355.5213178
Subtracting 4128 from 4280 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 16:
516 goes into 1520 2 times with a remainder of 488.
Write down 2 as next digit of the result. 
Result so far: 193355.52131782
Deduct 1032 from 1520 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final result is 193355.52131782 with a remainder of 4.88e-07.
