91474728 divided by 517 
The aim is to understand the frequency of 517 in 91474728.

Going ahead to step 1:
When dividing 9 by 517, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 517

Moving on to step 2:
91 divided by 517 is 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (4) from the dividend and append it to 91, then repeat: 914 / 517

Advancing to step 3:
517 can be fit into 914 1 times, resulting in a remainder of 397.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 397 after subtracting 517 from 914.
Append the next digit (7) from the dividend to 397 and continue with: 3977 / 517

Advancing to step 4:
If we divide 3977 by 517, we get 7 and a remainder of 358.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 3619 from 3977, we get 358.
Include the next digit (4) from the dividend after 358, then repeat: 3584 / 517

Advancing to step 5:
517 goes into 3584 6 times with a remainder of 482.
Write down 6 as next digit of the result. 
Result so far: 176.0
If we take 3102 away from 3584, we end up with 482.
Fetch the next digit (7) from the dividend, attach it to 482 and continue: 4827 / 517

Advancing to step 6:
517 can be fit into 4827 9 times, resulting in a remainder of 174.
The next digit of our result is 9. 
Result so far: 1769.0
Deduct 4653 from 4827 and we're left with 174.
Fetch the next digit (2) from the dividend, attach it to 174 and continue: 1742 / 517

Let's proceed to step 7:
The number 517 fits into 1742 3 times, leaving a remainder of 191.
Write down 3 as next digit of the result. 
Result so far: 17693.0
The remainder is 191 after subtracting 1551 from 1742.
Grab the next digit (8) from the dividend, add it to 191, then carry on: 1918 / 517

On to step 8:
The number 517 fits into 1918 3 times, leaving a remainder of 367.
Put 3 as the next digit of the answer. 
Result so far: 176933.0
Subtract 1551 from 1918 to get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 9:
The number 517 fits into 3670 7 times, leaving a remainder of 51.
The next digit of our result is 7. 
Result so far: 176933.7
If we take 3619 away from 3670, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
When dividing 510 by 517, we get 0 with a remainder of 510.
Record the quotient 0 as the next digit in the result. 
Result so far: 176933.7
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 11:
5100 divided by 517 is 9 with a remainder of 447.
Put 9 as the next digit of the answer. 
Result so far: 176933.709
If we take 4653 away from 5100, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Moving on to step 12:
The number 517 fits into 4470 8 times, leaving a remainder of 334.
Use 8 as the next digit of our solution. 
Result so far: 176933.7098
Subtracting 4136 from 4470 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 13:
If we divide 3340 by 517, we get 6 and a remainder of 238.
The number 6 becomes the next digit in our result. 
Result so far: 176933.70986
Deduct 3102 from 3340 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 14:
2380 divided by 517 is 4 with a remainder of 312.
The next digit of our result is 4. 
Result so far: 176933.709864
Subtracting 2068 from 2380 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.

Advancing to step 15:
517 goes into 3120 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 176933.7098646
The remainder is 18 after subtracting 3102 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 16:
517 can be fit into 180 0 times, resulting in a remainder of 180.
The next digit of our result is 0. 
Result so far: 176933.7098646
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 176933.7098646, with a leftover of 1.8e-07.
