We look at the division of 65021701 by 68 
The aim is to understand the frequency of 68 in 65021701.

Going ahead to step 1:
When dividing 6 by 68, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 68

Advancing to step 2:
68 can be fit into 65 0 times, resulting in a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 68

On to step 3:
68 goes into 650 9 times with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 612 from 650 and we're left with 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 68

On to step 4:
68 can be fit into 382 5 times, resulting in a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 95.0
The remainder is 42 after subtracting 340 from 382.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 68

Advancing to step 5:
68 can be fit into 421 6 times, resulting in a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 956.0
Deduct 408 from 421 and we're left with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 68

Step 6:
The number 68 fits into 137 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 9562.0
Subtracting 136 from 137 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 68

Let's proceed to step 7:
68 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 95620.0
If we take 0 away from 10, we end up with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 68

On to step 8:
68 goes into 101 1 times with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 956201.0
If we take 68 away from 101, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
68 can be fit into 330 4 times, resulting in a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 956201.4
The remainder is 58 after subtracting 272 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
The number 68 fits into 580 8 times, leaving a remainder of 36.
The next digit of our result is 8. 
Result so far: 956201.48
If we subtract 544 from 580, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
When dividing 360 by 68, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 956201.485
Subtract 340 from 360 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
68 goes into 200 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 956201.4852
Deduct 136 from 200 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
68 can be fit into 640 9 times, resulting in a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 956201.48529
If we take 612 away from 640, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
280 divided by 68 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 956201.485294
Deduct 272 from 280 and we're left 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.

On to step 15:
When dividing 80 by 68, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 956201.4852941
If we subtract 68 from 80, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 16:
68 goes into 120 1 times with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 956201.48529411
Deduct 68 from 120 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 956201.48529411, and the remainder is 5.2e-08.
