831600 ÷ 68 
The aim is to understand the frequency of 68 in 831600.

Going ahead to step 1:
When dividing 8 by 68, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 68

On to step 2:
When dividing 83 by 68, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 68 from 83 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 68

On to step 3:
If we divide 151 by 68, we get 2 and a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 15 after subtracting 136 from 151.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 68

Let's proceed to step 4:
When dividing 156 by 68, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Subtract 136 from 156 to get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 68

On to step 5:
68 goes into 200 2 times with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 1222.0
If we take 136 away from 200, we end up with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 68

Going ahead to step 6:
640 divided by 68 is 9 with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 12229.0
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.

Step 7:
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: 12229.4
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.

Let's proceed to step 8:
68 can be fit into 80 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 12229.41
The remainder is 12 after subtracting 68 from 80.
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 9:
68 goes into 120 1 times with a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 12229.411
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.

Our division results in 12229.411 with a remaining 0.0052.
