Let's divide 40256855 by 517
The aim is to understand the frequency of 517 in 40256855.

Going ahead to step 1:
When dividing 4 by 517, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 517

Step 2:
The number 517 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 517

Let's proceed to step 3:
402 divided by 517 is 0 with a remainder of 402.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 402, we get 402.
Append the next digit (5) from the dividend to 402 and continue with: 4025 / 517

On to step 4:
517 can be fit into 4025 7 times, resulting in a remainder of 406.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 3619 away from 4025, we end up with 406.
Append the next digit (6) from the dividend to 406 and continue with: 4066 / 517

On to step 5:
517 can be fit into 4066 7 times, resulting in a remainder of 447.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Deduct 3619 from 4066 and we're left with 447.
Grab the next digit (8) from the dividend, add it to 447, then carry on: 4478 / 517

Let's proceed to step 6:
517 goes into 4478 8 times with a remainder of 342.
Write down 8 as next digit of the result. 
Result so far: 778.0
The remainder is 342 after subtracting 4136 from 4478.
Append the next digit (5) from the dividend to 342 and continue with: 3425 / 517

Advancing to step 7:
The number 517 fits into 3425 6 times, leaving a remainder of 323.
The number 6 becomes the next digit in our result. 
Result so far: 7786.0
Deduct 3102 from 3425 and we're left with 323.
Append the next digit (5) from the dividend to 323 and continue with: 3235 / 517

Let's proceed to step 8:
If we divide 3235 by 517, we get 6 and a remainder of 133.
Use 6 as the next digit of our solution. 
Result so far: 77866.0
The remainder is 133 after subtracting 3102 from 3235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 9:
If we divide 1330 by 517, we get 2 and a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 77866.2
The remainder is 296 after subtracting 1034 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 10:
The number 517 fits into 2960 5 times, leaving a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 77866.25
Subtracting 2585 from 2960 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 11:
The number 517 fits into 3750 7 times, leaving a remainder of 131.
The number 7 becomes the next digit in our result. 
Result so far: 77866.257
The remainder is 131 after subtracting 3619 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Let's proceed to step 12:
When dividing 1310 by 517, we get 2 with a remainder of 276.
Use 2 as the next digit of our solution. 
Result so far: 77866.2572
If we subtract 1034 from 1310, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 13:
When dividing 2760 by 517, we get 5 with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 77866.25725
Deduct 2585 from 2760 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 14:
The number 517 fits into 1750 3 times, leaving a remainder of 199.
Write down 3 as next digit of the result. 
Result so far: 77866.257253
If we subtract 1551 from 1750, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 15:
517 goes into 1990 3 times with a remainder of 439.
The number 3 becomes the next digit in our result. 
Result so far: 77866.2572533
Deduct 1551 from 1990 and we're left with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

The final result is 77866.2572533 with a remainder of 4.39e-06.
