We look at the division of 43150754 by 517 
The aim is to understand the frequency of 517 in 43150754.

Advancing to step 1:
The number 517 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 517

Step 2:
517 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 517

Advancing to step 3:
If we divide 431 by 517, we get 0 and a remainder of 431.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 431, we get 431.
Include the next digit (5) from the dividend after 431, then repeat: 4315 / 517

Moving on to step 4:
If we divide 4315 by 517, we get 8 and a remainder of 179.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 4136 from 4315 leaves us with 179.
Append the next digit (0) from the dividend to 179 and continue with: 1790 / 517

Moving on to step 5:
The number 517 fits into 1790 3 times, leaving a remainder of 239.
The next digit of our result is 3. 
Result so far: 83.0
If we take 1551 away from 1790, we end up with 239.
Bring next digit (7) of the dividend behind the 239 and repeat the process: 2397 / 517

Let's proceed to step 6:
If we divide 2397 by 517, we get 4 and a remainder of 329.
Put 4 as the next digit of the answer. 
Result so far: 834.0
If we subtract 2068 from 2397, we get 329.
Take the next digit (5) from the dividend and append it to 329, then repeat: 3295 / 517

Advancing to step 7:
When dividing 3295 by 517, we get 6 with a remainder of 193.
Record the quotient 6 as the next digit in the result. 
Result so far: 8346.0
If we subtract 3102 from 3295, we get 193.
Take the next digit (4) from the dividend and append it to 193, then repeat: 1934 / 517

Step 8:
517 can be fit into 1934 3 times, resulting in a remainder of 383.
Put 3 as the next digit of the answer. 
Result so far: 83463.0
Deduct 1551 from 1934 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Going ahead to step 9:
3830 divided by 517 is 7 with a remainder of 211.
The next digit of our result is 7. 
Result so far: 83463.7
If we take 3619 away from 3830, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 10:
517 goes into 2110 4 times with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 83463.74
Subtract 2068 from 2110 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
If we divide 420 by 517, we get 0 and a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 83463.74
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 12:
The number 517 fits into 4200 8 times, leaving a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 83463.7408
Subtract 4136 from 4200 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
The number 517 fits into 640 1 times, leaving a remainder of 123.
Record the quotient 1 as the next digit in the result. 
Result so far: 83463.74081
If we subtract 517 from 640, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 14:
517 goes into 1230 2 times with a remainder of 196.
Put 2 as the next digit of the answer. 
Result so far: 83463.740812
If we take 1034 away from 1230, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 15:
When dividing 1960 by 517, we get 3 with a remainder of 409.
The next digit of our result is 3. 
Result so far: 83463.7408123
Deduct 1551 from 1960 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 16:
4090 divided by 517 is 7 with a remainder of 471.
The next digit of our result is 7. 
Result so far: 83463.74081237
If we subtract 3619 from 4090, we get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Our division results in 83463.74081237 with a remaining 4.71e-07.
