809137 ÷ 68 
The aim is to understand the frequency of 68 in 809137.

Moving on 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.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 68

Going ahead to step 2:
68 goes into 80 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 68 from 80, we get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 68

On to step 3:
If we divide 129 by 68, we get 1 and a remainder of 61.
The next digit of our result is 1. 
Result so far: 11.0
If we take 68 away from 129, we end up with 61.
Fetch the next digit (1) from the dividend, attach it to 61 and continue: 611 / 68

Going ahead to step 4:
The number 68 fits into 611 8 times, leaving a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtract 544 from 611 to get 67.
Fetch the next digit (3) from the dividend, attach it to 67 and continue: 673 / 68

Advancing to step 5:
The number 68 fits into 673 9 times, leaving a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 1189.0
If we subtract 612 from 673, we get 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 68

On to step 6:
When dividing 617 by 68, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 11899.0
Subtract 612 from 617 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
68 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 11899.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 68 is 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 11899.07
The remainder is 24 after subtracting 476 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 68, we get 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 11899.073
The remainder is 36 after subtracting 204 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
68 goes into 360 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 11899.0735
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.

Moving on to step 11:
If we divide 200 by 68, we get 2 and a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 11899.07352
Subtracting 136 from 200 leaves us 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.

Going ahead to step 12:
When dividing 640 by 68, we get 9 with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 11899.073529
The remainder is 28 after subtracting 612 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
68 can be fit into 280 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 11899.0735294
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.

Advancing to step 14:
When dividing 80 by 68, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 11899.07352941
If we take 68 away from 80, 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.

The final outcome is 11899.07352941, with a leftover of 1.2e-08.
