We look at the division of 72160802 by 619 
The aim is to understand the frequency of 619 in 72160802.

Let's proceed to step 1:
When dividing 7 by 619, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 619

Step 2:
619 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 619

Moving on to step 3:
If we divide 721 by 619, we get 1 and a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 619 away from 721, we end up with 102.
Take the next digit (6) from the dividend and append it to 102, then repeat: 1026 / 619

Advancing to step 4:
The number 619 fits into 1026 1 times, leaving a remainder of 407.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 619 from 1026 to get 407.
Bring next digit (0) of the dividend behind the 407 and repeat the process: 4070 / 619

Advancing to step 5:
The number 619 fits into 4070 6 times, leaving a remainder of 356.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Deduct 3714 from 4070 and we're left with 356.
Bring next digit (8) of the dividend behind the 356 and repeat the process: 3568 / 619

Moving on to step 6:
619 can be fit into 3568 5 times, resulting in a remainder of 473.
Write down 5 as next digit of the result. 
Result so far: 1165.0
Subtract 3095 from 3568 to get 473.
Include the next digit (0) from the dividend after 473, then repeat: 4730 / 619

Going ahead to step 7:
The number 619 fits into 4730 7 times, leaving a remainder of 397.
Use 7 as the next digit of our solution. 
Result so far: 11657.0
Subtracting 4333 from 4730 leaves us with 397.
Take the next digit (2) from the dividend and append it to 397, then repeat: 3972 / 619

Going ahead to step 8:
3972 divided by 619 is 6 with a remainder of 258.
Put 6 as the next digit of the answer. 
Result so far: 116576.0
Subtract 3714 from 3972 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 9:
When dividing 2580 by 619, we get 4 with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 116576.4
Deduct 2476 from 2580 and we're left 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.

Step 10:
619 goes into 1040 1 times with a remainder of 421.
Put 1 as the next digit of the answer. 
Result so far: 116576.41
Deduct 619 from 1040 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 11:
619 can be fit into 4210 6 times, resulting in a remainder of 496.
Put 6 as the next digit of the answer. 
Result so far: 116576.416
Subtract 3714 from 4210 to get 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 12:
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: 116576.4168
Subtracting 4952 from 4960 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
619 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 116576.4168
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
619 can be fit into 800 1 times, resulting in a remainder of 181.
The next digit of our result is 1. 
Result so far: 116576.416801
If we subtract 619 from 800, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 15:
619 goes into 1810 2 times with a remainder of 572.
Write down 2 as next digit of the result. 
Result so far: 116576.4168012
If we subtract 1238 from 1810, we 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.

Step 16:
5720 divided by 619 is 9 with a remainder of 149.
Put 9 as the next digit of the answer. 
Result so far: 116576.41680129
Subtracting 5571 from 5720 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

The final result is 116576.41680129 with a remainder of 1.49e-07.
