We look at the division of 68638219 by 616 
The aim is to understand the frequency of 616 in 68638219.

Step 1:
616 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 616

Moving on to step 2:
616 can be fit into 68 0 times, resulting in a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 616

Moving on to step 3:
If we divide 686 by 616, we get 1 and a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 616 away from 686, we end up with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 616

Step 4:
616 goes into 703 1 times with a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 616 away from 703, we end up with 87.
Bring next digit (8) of the dividend behind the 87 and repeat the process: 878 / 616

Advancing to step 5:
616 goes into 878 1 times with a remainder of 262.
Write down 1 as next digit of the result. 
Result so far: 111.0
Deduct 616 from 878 and we're left with 262.
Fetch the next digit (2) from the dividend, attach it to 262 and continue: 2622 / 616

On to step 6:
If we divide 2622 by 616, we get 4 and a remainder of 158.
Record the quotient 4 as the next digit in the result. 
Result so far: 1114.0
Subtracting 2464 from 2622 leaves us with 158.
Include the next digit (1) from the dividend after 158, then repeat: 1581 / 616

Going ahead to step 7:
1581 divided by 616 is 2 with a remainder of 349.
The next digit of our result is 2. 
Result so far: 11142.0
Subtracting 1232 from 1581 leaves us with 349.
Fetch the next digit (9) from the dividend, attach it to 349 and continue: 3499 / 616

Moving on to step 8:
616 can be fit into 3499 5 times, resulting in a remainder of 419.
The number 5 becomes the next digit in our result. 
Result so far: 111425.0
Subtract 3080 from 3499 to get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 9:
If we divide 4190 by 616, we get 6 and a remainder of 494.
Use 6 as the next digit of our solution. 
Result so far: 111425.6
If we take 3696 away from 4190, 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.

Step 10:
616 goes into 4940 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 111425.68
If we take 4928 away from 4940, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
616 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 111425.68
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
616 goes into 1200 1 times with a remainder of 584.
Record the quotient 1 as the next digit in the result. 
Result so far: 111425.6801
If we take 616 away from 1200, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Advancing to step 13:
616 goes into 5840 9 times with a remainder of 296.
The next digit of our result is 9. 
Result so far: 111425.68019
Subtracting 5544 from 5840 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 14:
When dividing 2960 by 616, we get 4 with a remainder of 496.
The number 4 becomes the next digit in our result. 
Result so far: 111425.680194
Subtract 2464 from 2960 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.

Moving on to step 15:
If we divide 4960 by 616, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 111425.6801948
Subtract 4928 from 4960 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 16:
320 divided by 616 is 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 111425.6801948
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

In conclusion, the division gives 111425.6801948 with a balance of 3.2e-07.
