We look at the division of 77470115 by 518 
The aim is to understand the frequency of 518 in 77470115.

On to step 1:
If we divide 7 by 518, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 518

Step 2:
518 goes into 77 0 times with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 518

Advancing to step 3:
774 divided by 518 is 1 with a remainder of 256.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 518 from 774, we get 256.
Append the next digit (7) from the dividend to 256 and continue with: 2567 / 518

Moving on to step 4:
If we divide 2567 by 518, we get 4 and a remainder of 495.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 495 after subtracting 2072 from 2567.
Grab the next digit (0) from the dividend, add it to 495, then carry on: 4950 / 518

Let's proceed to step 5:
4950 divided by 518 is 9 with a remainder of 288.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
The remainder is 288 after subtracting 4662 from 4950.
Take the next digit (1) from the dividend and append it to 288, then repeat: 2881 / 518

Moving on to step 6:
518 can be fit into 2881 5 times, resulting in a remainder of 291.
Write down 5 as next digit of the result. 
Result so far: 1495.0
Deduct 2590 from 2881 and we're left with 291.
Append the next digit (1) from the dividend to 291 and continue with: 2911 / 518

On to step 7:
When dividing 2911 by 518, we get 5 with a remainder of 321.
Write down 5 as next digit of the result. 
Result so far: 14955.0
If we subtract 2590 from 2911, we get 321.
Append the next digit (5) from the dividend to 321 and continue with: 3215 / 518

Moving on to step 8:
If we divide 3215 by 518, we get 6 and a remainder of 107.
Record the quotient 6 as the next digit in the result. 
Result so far: 149556.0
Subtracting 3108 from 3215 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 9:
518 can be fit into 1070 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 149556.2
The remainder is 34 after subtracting 1036 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
340 divided by 518 is 0 with a remainder of 340.
The next digit of our result is 0. 
Result so far: 149556.2
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 11:
If we divide 3400 by 518, we get 6 and a remainder of 292.
The next digit of our result is 6. 
Result so far: 149556.206
If we subtract 3108 from 3400, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 12:
The number 518 fits into 2920 5 times, leaving a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 149556.2065
The remainder is 330 after subtracting 2590 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 13:
518 can be fit into 3300 6 times, resulting in a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 149556.20656
Deduct 3108 from 3300 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
When dividing 1920 by 518, we get 3 with a remainder of 366.
Record the quotient 3 as the next digit in the result. 
Result so far: 149556.206563
If we take 1554 away from 1920, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 15:
When dividing 3660 by 518, we get 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 149556.2065637
If we take 3626 away from 3660, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 16:
518 can be fit into 340 0 times, resulting in a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 149556.2065637
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

In conclusion, the division gives 149556.2065637 with a balance of 3.4e-07.
