We're dividing 57857140 by 518 
The aim is to understand the frequency of 518 in 57857140.

Moving on to step 1:
5 divided by 518 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 518

On to step 2:
If we divide 57 by 518, we get 0 and a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 518

Step 3:
When dividing 578 by 518, we get 1 with a remainder of 60.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 518 from 578, we get 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 518

Moving on to step 4:
518 can be fit into 605 1 times, resulting in a remainder of 87.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 87 after subtracting 518 from 605.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 518

Advancing to step 5:
The number 518 fits into 877 1 times, leaving a remainder of 359.
Put 1 as the next digit of the answer. 
Result so far: 111.0
If we subtract 518 from 877, we get 359.
Fetch the next digit (1) from the dividend, attach it to 359 and continue: 3591 / 518

Let's proceed to step 6:
The number 518 fits into 3591 6 times, leaving a remainder of 483.
Record the quotient 6 as the next digit in the result. 
Result so far: 1116.0
If we take 3108 away from 3591, we end up with 483.
Fetch the next digit (4) from the dividend, attach it to 483 and continue: 4834 / 518

On to step 7:
4834 divided by 518 is 9 with a remainder of 172.
Use 9 as the next digit of our solution. 
Result so far: 11169.0
The remainder is 172 after subtracting 4662 from 4834.
Grab the next digit (0) from the dividend, add it to 172, then carry on: 1720 / 518

Moving on to step 8:
1720 divided by 518 is 3 with a remainder of 166.
Record the quotient 3 as the next digit in the result. 
Result so far: 111693.0
If we subtract 1554 from 1720, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
1660 divided by 518 is 3 with a remainder of 106.
Use 3 as the next digit of our solution. 
Result so far: 111693.3
If we take 1554 away from 1660, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 10:
518 goes into 1060 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 111693.32
Subtract 1036 from 1060 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
518 can be fit into 240 0 times, resulting in a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 111693.32
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 12:
518 goes into 2400 4 times with a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 111693.3204
If we take 2072 away from 2400, we end up 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.

Let's proceed to step 13:
518 goes into 3280 6 times with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 111693.32046
If we subtract 3108 from 3280, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 14:
518 can be fit into 1720 3 times, resulting in a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 111693.320463
Subtracting 1554 from 1720 leaves us 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.

Going ahead to step 15:
1660 divided by 518 is 3 with a remainder of 106.
The next digit of our result is 3. 
Result so far: 111693.3204633
If we take 1554 away from 1660, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The final outcome is 111693.3204633, with a leftover of 1.06e-06.
