We look at the division of 18869130 by 607 
The aim is to understand the frequency of 607 in 18869130.

Step 1:
If we divide 1 by 607, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 607

Moving on to step 2:
18 divided by 607 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 607

Advancing to step 3:
The number 607 fits into 188 0 times, leaving a remainder of 188.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 188 and we're left with 188.
Grab the next digit (6) from the dividend, add it to 188, then carry on: 1886 / 607

On to step 4:
607 goes into 1886 3 times with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 1821 from 1886 leaves us with 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 607

Going ahead to step 5:
607 goes into 659 1 times with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 607 from 659 and we're left with 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 607

Moving on to step 6:
607 can be fit into 521 0 times, resulting in a remainder of 521.
Write down 0 as next digit of the result. 
Result so far: 310.0
Deduct 0 from 521 and we're left with 521.
Include the next digit (3) from the dividend after 521, then repeat: 5213 / 607

Going ahead to step 7:
If we divide 5213 by 607, we get 8 and a remainder of 357.
Record the quotient 8 as the next digit in the result. 
Result so far: 3108.0
The remainder is 357 after subtracting 4856 from 5213.
Include the next digit (0) from the dividend after 357, then repeat: 3570 / 607

Advancing to step 8:
When dividing 3570 by 607, we get 5 with a remainder of 535.
The number 5 becomes the next digit in our result. 
Result so far: 31085.0
The remainder is 535 after subtracting 3035 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Advancing to step 9:
607 can be fit into 5350 8 times, resulting in a remainder of 494.
Write down 8 as next digit of the result. 
Result so far: 31085.8
If we take 4856 away from 5350, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 10:
4940 divided by 607 is 8 with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 31085.88
If we take 4856 away from 4940, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 31085.88 with a remaining 0.084.
