We look at the division of 8968766 by 607 
The aim is to understand the frequency of 607 in 8968766.

On to step 1:
8 divided by 607 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 607

Advancing to step 2:
89 divided by 607 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 607

Moving on to step 3:
If we divide 896 by 607, we get 1 and a remainder of 289.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 289 after subtracting 607 from 896.
Take the next digit (8) from the dividend and append it to 289, then repeat: 2898 / 607

Let's proceed to step 4:
The number 607 fits into 2898 4 times, leaving a remainder of 470.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 2428 from 2898 leaves us with 470.
Include the next digit (7) from the dividend after 470, then repeat: 4707 / 607

Let's proceed to step 5:
If we divide 4707 by 607, we get 7 and a remainder of 458.
Use 7 as the next digit of our solution. 
Result so far: 147.0
The remainder is 458 after subtracting 4249 from 4707.
Append the next digit (6) from the dividend to 458 and continue with: 4586 / 607

Advancing to step 6:
607 goes into 4586 7 times with a remainder of 337.
The number 7 becomes the next digit in our result. 
Result so far: 1477.0
Subtract 4249 from 4586 to get 337.
Grab the next digit (6) from the dividend, add it to 337, then carry on: 3376 / 607

Advancing to step 7:
When dividing 3376 by 607, we get 5 with a remainder of 341.
Use 5 as the next digit of our solution. 
Result so far: 14775.0
If we subtract 3035 from 3376, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 8:
607 can be fit into 3410 5 times, resulting in a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 14775.5
Deduct 3035 from 3410 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 9:
The number 607 fits into 3750 6 times, leaving a remainder of 108.
The next digit of our result is 6. 
Result so far: 14775.56
Subtracting 3642 from 3750 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 10:
When dividing 1080 by 607, we get 1 with a remainder of 473.
The next digit of our result is 1. 
Result so far: 14775.561
Deduct 607 from 1080 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

On to step 11:
If we divide 4730 by 607, we get 7 and a remainder of 481.
The number 7 becomes the next digit in our result. 
Result so far: 14775.5617
Subtracting 4249 from 4730 leaves us with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Moving on to step 12:
When dividing 4810 by 607, we get 7 with a remainder of 561.
Record the quotient 7 as the next digit in the result. 
Result so far: 14775.56177
Deduct 4249 from 4810 and we're left with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

After the division, we end up with 14775.56177 and a remainder of 0.000561.
