We're dividing 66751005 by 619 
The aim is to understand the frequency of 619 in 66751005.

Going ahead to step 1:
The number 619 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 619

Moving on to step 2:
If we divide 66 by 619, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 619

Step 3:
619 can be fit into 667 1 times, resulting in a remainder of 48.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 48 after subtracting 619 from 667.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 619

Moving on to step 4:
485 divided by 619 is 0 with a remainder of 485.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 485, we get 485.
Take the next digit (1) from the dividend and append it to 485, then repeat: 4851 / 619

Let's proceed to step 5:
The number 619 fits into 4851 7 times, leaving a remainder of 518.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
The remainder is 518 after subtracting 4333 from 4851.
Bring next digit (0) of the dividend behind the 518 and repeat the process: 5180 / 619

Let's proceed to step 6:
619 goes into 5180 8 times with a remainder of 228.
The number 8 becomes the next digit in our result. 
Result so far: 1078.0
Deduct 4952 from 5180 and we're left with 228.
Fetch the next digit (0) from the dividend, attach it to 228 and continue: 2280 / 619

Going ahead to step 7:
If we divide 2280 by 619, we get 3 and a remainder of 423.
Write down 3 as next digit of the result. 
Result so far: 10783.0
Deduct 1857 from 2280 and we're left with 423.
Fetch the next digit (5) from the dividend, attach it to 423 and continue: 4235 / 619

On to step 8:
The number 619 fits into 4235 6 times, leaving a remainder of 521.
Use 6 as the next digit of our solution. 
Result so far: 107836.0
Subtracting 3714 from 4235 leaves us with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Advancing to step 9:
The number 619 fits into 5210 8 times, leaving a remainder of 258.
The number 8 becomes the next digit in our result. 
Result so far: 107836.8
Subtracting 4952 from 5210 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 10:
619 goes into 2580 4 times with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 107836.84
Subtracting 2476 from 2580 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 11:
619 can be fit into 1040 1 times, resulting in a remainder of 421.
Record the quotient 1 as the next digit in the result. 
Result so far: 107836.841
The remainder is 421 after subtracting 619 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Step 12:
When dividing 4210 by 619, we get 6 with a remainder of 496.
Use 6 as the next digit of our solution. 
Result so far: 107836.8416
Subtracting 3714 from 4210 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 13:
If we divide 4960 by 619, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 107836.84168
The remainder is 8 after subtracting 4952 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
619 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 107836.84168
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
The number 619 fits into 800 1 times, leaving a remainder of 181.
Write down 1 as next digit of the result. 
Result so far: 107836.8416801
Deduct 619 from 800 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Step 16:
When dividing 1810 by 619, we get 2 with a remainder of 572.
Put 2 as the next digit of the answer. 
Result so far: 107836.84168012
Subtract 1238 from 1810 to get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Our division results in 107836.84168012 with a remaining 5.72e-07.
