3903750 ÷ 516 
The aim is to understand the frequency of 516 in 3903750.

Moving on to step 1:
If we divide 3 by 516, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 516

Let's proceed to step 2:
39 divided by 516 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 516

Moving on to step 3:
The number 516 fits into 390 0 times, leaving a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 390 and we're left with 390.
Grab the next digit (3) from the dividend, add it to 390, then carry on: 3903 / 516

Let's proceed to step 4:
When dividing 3903 by 516, we get 7 with a remainder of 291.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 3612 from 3903 leaves us with 291.
Grab the next digit (7) from the dividend, add it to 291, then carry on: 2917 / 516

Let's proceed to step 5:
If we divide 2917 by 516, we get 5 and a remainder of 337.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 2580 from 2917, we get 337.
Append the next digit (5) from the dividend to 337 and continue with: 3375 / 516

Let's proceed to step 6:
516 can be fit into 3375 6 times, resulting in a remainder of 279.
Record the quotient 6 as the next digit in the result. 
Result so far: 756.0
Deduct 3096 from 3375 and we're left with 279.
Append the next digit (0) from the dividend to 279 and continue with: 2790 / 516

On to step 7:
516 goes into 2790 5 times with a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 7565.0
If we subtract 2580 from 2790, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 8:
When dividing 2100 by 516, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 7565.4
If we subtract 2064 from 2100, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
360 divided by 516 is 0 with a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 7565.4
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 10:
3600 divided by 516 is 6 with a remainder of 504.
Use 6 as the next digit of our solution. 
Result so far: 7565.406
Subtract 3096 from 3600 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 11:
516 goes into 5040 9 times with a remainder of 396.
The number 9 becomes the next digit in our result. 
Result so far: 7565.4069
The remainder is 396 after subtracting 4644 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 12:
When dividing 3960 by 516, we get 7 with a remainder of 348.
Record the quotient 7 as the next digit in the result. 
Result so far: 7565.40697
Subtract 3612 from 3960 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 13:
When dividing 3480 by 516, we get 6 with a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 7565.406976
Deduct 3096 from 3480 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 14:
3840 divided by 516 is 7 with a remainder of 228.
Write down 7 as next digit of the result. 
Result so far: 7565.4069767
Subtracting 3612 from 3840 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 15:
516 can be fit into 2280 4 times, resulting in a remainder of 216.
The next digit of our result is 4. 
Result so far: 7565.40697674
The remainder is 216 after subtracting 2064 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The final result is 7565.40697674 with a remainder of 2.16e-07.
