71588660 divided by 518 
The aim is to understand the frequency of 518 in 71588660.

Advancing to step 1:
7 divided by 518 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 518

Step 2:
When dividing 71 by 518, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 518

Moving on to step 3:
If we divide 715 by 518, we get 1 and a remainder of 197.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 518 from 715 to get 197.
Append the next digit (8) from the dividend to 197 and continue with: 1978 / 518

Let's proceed to step 4:
If we divide 1978 by 518, we get 3 and a remainder of 424.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1554 from 1978 leaves us with 424.
Take the next digit (8) from the dividend and append it to 424, then repeat: 4248 / 518

Advancing to step 5:
When dividing 4248 by 518, we get 8 with a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 138.0
Subtracting 4144 from 4248 leaves us with 104.
Include the next digit (6) from the dividend after 104, then repeat: 1046 / 518

Let's proceed to step 6:
If we divide 1046 by 518, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 1382.0
If we subtract 1036 from 1046, we get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 518

On to step 7:
518 can be fit into 106 0 times, resulting in a remainder of 106.
The number 0 becomes the next digit in our result. 
Result so far: 13820.0
Subtracting 0 from 106 leaves us with 106.
Append the next digit (0) from the dividend to 106 and continue with: 1060 / 518

Advancing to step 8:
1060 divided by 518 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 138202.0
The remainder is 24 after subtracting 1036 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
240 divided by 518 is 0 with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 138202.0
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
518 can be fit into 2400 4 times, resulting in a remainder of 328.
Record the quotient 4 as the next digit in the result. 
Result so far: 138202.04
Subtracting 2072 from 2400 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 11:
3280 divided by 518 is 6 with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 138202.046
Subtracting 3108 from 3280 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 12:
When dividing 1720 by 518, we get 3 with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 138202.0463
If we take 1554 away from 1720, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 13:
If we divide 1660 by 518, we get 3 and a remainder of 106.
Use 3 as the next digit of our solution. 
Result so far: 138202.04633
If we subtract 1554 from 1660, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Our division results in 138202.04633 with a remaining 0.000106.
