We're dividing 70170253 by 517 
The aim is to understand the frequency of 517 in 70170253.

Let's proceed to step 1:
7 divided by 517 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 517

Step 2:
When dividing 70 by 517, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 517

Advancing to step 3:
The number 517 fits into 701 1 times, leaving a remainder of 184.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 517 from 701, we get 184.
Take the next digit (7) from the dividend and append it to 184, then repeat: 1847 / 517

Step 4:
If we divide 1847 by 517, we get 3 and a remainder of 296.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1551 from 1847 to get 296.
Take the next digit (0) from the dividend and append it to 296, then repeat: 2960 / 517

Advancing to step 5:
2960 divided by 517 is 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
If we subtract 2585 from 2960, we get 375.
Fetch the next digit (2) from the dividend, attach it to 375 and continue: 3752 / 517

Moving on to step 6:
If we divide 3752 by 517, we get 7 and a remainder of 133.
Use 7 as the next digit of our solution. 
Result so far: 1357.0
Deduct 3619 from 3752 and we're left with 133.
Grab the next digit (5) from the dividend, add it to 133, then carry on: 1335 / 517

On to step 7:
If we divide 1335 by 517, we get 2 and a remainder of 301.
Put 2 as the next digit of the answer. 
Result so far: 13572.0
Subtract 1034 from 1335 to get 301.
Fetch the next digit (3) from the dividend, attach it to 301 and continue: 3013 / 517

Going ahead to step 8:
When dividing 3013 by 517, we get 5 with a remainder of 428.
The number 5 becomes the next digit in our result. 
Result so far: 135725.0
If we subtract 2585 from 3013, we get 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 9:
517 can be fit into 4280 8 times, resulting in a remainder of 144.
The number 8 becomes the next digit in our result. 
Result so far: 135725.8
Subtracting 4136 from 4280 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 10:
1440 divided by 517 is 2 with a remainder of 406.
Record the quotient 2 as the next digit in the result. 
Result so far: 135725.82
If we subtract 1034 from 1440, we get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 11:
If we divide 4060 by 517, we get 7 and a remainder of 441.
Put 7 as the next digit of the answer. 
Result so far: 135725.827
If we take 3619 away from 4060, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Advancing to step 12:
4410 divided by 517 is 8 with a remainder of 274.
Write down 8 as next digit of the result. 
Result so far: 135725.8278
Subtracting 4136 from 4410 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 13:
2740 divided by 517 is 5 with a remainder of 155.
The next digit of our result is 5. 
Result so far: 135725.82785
Deduct 2585 from 2740 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 14:
517 can be fit into 1550 2 times, resulting in a remainder of 516.
Use 2 as the next digit of our solution. 
Result so far: 135725.827852
The remainder is 516 after subtracting 1034 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 15:
If we divide 5160 by 517, we get 9 and a remainder of 507.
Use 9 as the next digit of our solution. 
Result so far: 135725.8278529
Deduct 4653 from 5160 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Let's proceed to step 16:
If we divide 5070 by 517, we get 9 and a remainder of 417.
The number 9 becomes the next digit in our result. 
Result so far: 135725.82785299
The remainder is 417 after subtracting 4653 from 5070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

The quotient of the division is 135725.82785299, and the remainder is 4.17e-07.
