40386384 ÷ 516 
The aim is to understand the frequency of 516 in 40386384.

Advancing to step 1:
If we divide 4 by 516, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 516

Let's proceed to step 2:
40 divided by 516 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 516

Let's proceed to step 3:
The number 516 fits into 403 0 times, leaving a remainder of 403.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 403 after subtracting 0 from 403.
Append the next digit (8) from the dividend to 403 and continue with: 4038 / 516

Step 4:
When dividing 4038 by 516, we get 7 with a remainder of 426.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 3612 from 4038 leaves us with 426.
Take the next digit (6) from the dividend and append it to 426, then repeat: 4266 / 516

Going ahead to step 5:
4266 divided by 516 is 8 with a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we subtract 4128 from 4266, we get 138.
Append the next digit (3) from the dividend to 138 and continue with: 1383 / 516

Moving on to step 6:
If we divide 1383 by 516, we get 2 and a remainder of 351.
Use 2 as the next digit of our solution. 
Result so far: 782.0
If we take 1032 away from 1383, we end up with 351.
Grab the next digit (8) from the dividend, add it to 351, then carry on: 3518 / 516

Advancing to step 7:
516 goes into 3518 6 times with a remainder of 422.
The number 6 becomes the next digit in our result. 
Result so far: 7826.0
Subtracting 3096 from 3518 leaves us with 422.
Fetch the next digit (4) from the dividend, attach it to 422 and continue: 4224 / 516

Let's proceed to step 8:
516 goes into 4224 8 times with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 78268.0
Subtract 4128 from 4224 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
516 goes into 960 1 times with a remainder of 444.
Record the quotient 1 as the next digit in the result. 
Result so far: 78268.1
Subtract 516 from 960 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 10:
When dividing 4440 by 516, we get 8 with a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 78268.18
Subtracting 4128 from 4440 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 11:
The number 516 fits into 3120 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 78268.186
Subtract 3096 from 3120 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
516 can be fit into 240 0 times, resulting in a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 78268.186
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
516 can be fit into 2400 4 times, resulting in a remainder of 336.
The next digit of our result is 4. 
Result so far: 78268.18604
If we subtract 2064 from 2400, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 14:
When dividing 3360 by 516, we get 6 with a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 78268.186046
Deduct 3096 from 3360 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 15:
The number 516 fits into 2640 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 78268.1860465
Subtract 2580 from 2640 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 16:
The number 516 fits into 600 1 times, leaving a remainder of 84.
The next digit of our result is 1. 
Result so far: 78268.18604651
Subtract 516 from 600 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

In conclusion, the division gives 78268.18604651 with a balance of 8.4e-08.
