591995 ÷ 68 
The aim is to understand the frequency of 68 in 591995.

Going ahead to step 1:
The number 68 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 68

Let's proceed to step 2:
The number 68 fits into 59 0 times, leaving a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 68

Advancing to step 3:
When dividing 591 by 68, we get 8 with a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 47 after subtracting 544 from 591.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 68

Moving on to step 4:
The number 68 fits into 479 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Deduct 476 from 479 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 68

Going ahead to step 5:
68 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 870.0
If we subtract 0 from 39, we get 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 68

On to step 6:
68 can be fit into 395 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 8705.0
Subtracting 340 from 395 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
When dividing 550 by 68, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8705.8
If we take 544 away from 550, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 68, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 8705.8
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
68 goes into 600 8 times with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 8705.808
If we take 544 away from 600, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
68 goes into 560 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 8705.8088
Subtracting 544 from 560 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 8705.8088, with a leftover of 0.00016.
