We're dividing 577837 by 68 
The aim is to understand the frequency of 68 in 577837.

On to step 1:
When dividing 5 by 68, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 68

Let's proceed to step 2:
68 can be fit into 57 0 times, resulting in a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 68

On to step 3:
68 can be fit into 577 8 times, resulting in a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 544 from 577, we get 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 68

Let's proceed to step 4:
68 can be fit into 338 4 times, resulting in a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Deduct 272 from 338 and we're left with 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 68

Advancing to step 5:
If we divide 663 by 68, we get 9 and a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 849.0
If we take 612 away from 663, we end up with 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 68

On to step 6:
The number 68 fits into 517 7 times, leaving a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 8497.0
Subtracting 476 from 517 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
68 goes into 410 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 8497.6
Subtract 408 from 410 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 68, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8497.6
If we subtract 0 from 20, we 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.

On to step 9:
68 can be fit into 200 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 8497.602
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 10:
When dividing 640 by 68, we get 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 8497.6029
Deduct 612 from 640 and we're left 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.

Advancing to step 11:
68 can be fit into 280 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 8497.60294
Subtracting 272 from 280 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.

Advancing to step 12:
80 divided by 68 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 8497.602941
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.

Let's proceed to step 13:
68 can be fit into 120 1 times, resulting in a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 8497.6029411
Subtracting 68 from 120 leaves us 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.

In conclusion, the division gives 8497.6029411 with a balance of 5.2e-07.
