We're dividing 87929427 by 517 
The aim is to understand the frequency of 517 in 87929427.

Going ahead to step 1:
517 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 517

Moving on to step 2:
517 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 517

Going ahead to step 3:
879 divided by 517 is 1 with a remainder of 362.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 517 from 879 to get 362.
Take the next digit (2) from the dividend and append it to 362, then repeat: 3622 / 517

Moving on to step 4:
517 can be fit into 3622 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 3619 from 3622 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 517

On to step 5:
517 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 170.0
Subtract 0 from 39 to get 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 517

Let's proceed to step 6:
517 can be fit into 394 0 times, resulting in a remainder of 394.
The number 0 becomes the next digit in our result. 
Result so far: 1700.0
If we take 0 away from 394, we end up with 394.
Take the next digit (2) from the dividend and append it to 394, then repeat: 3942 / 517

Advancing to step 7:
3942 divided by 517 is 7 with a remainder of 323.
Write down 7 as next digit of the result. 
Result so far: 17007.0
Subtracting 3619 from 3942 leaves us with 323.
Bring next digit (7) of the dividend behind the 323 and repeat the process: 3237 / 517

Step 8:
If we divide 3237 by 517, we get 6 and a remainder of 135.
Record the quotient 6 as the next digit in the result. 
Result so far: 170076.0
The remainder is 135 after subtracting 3102 from 3237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
517 goes into 1350 2 times with a remainder of 316.
Put 2 as the next digit of the answer. 
Result so far: 170076.2
If we take 1034 away from 1350, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 10:
The number 517 fits into 3160 6 times, leaving a remainder of 58.
The next digit of our result is 6. 
Result so far: 170076.26
If we take 3102 away from 3160, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
517 goes into 580 1 times with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 170076.261
If we take 517 away from 580, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 12:
When dividing 630 by 517, we get 1 with a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 170076.2611
The remainder is 113 after subtracting 517 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

The final outcome is 170076.2611, with a leftover of 0.00113.
