Let's divide 843709 by 68
The aim is to understand the frequency of 68 in 843709.

Advancing to step 1:
68 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 68

On to step 2:
If we divide 84 by 68, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 68 away from 84, we end up with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 68

Moving on to step 3:
68 goes into 163 2 times with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 136 from 163 and we're left with 27.
Include the next digit (7) from the dividend after 27, then repeat: 277 / 68

Step 4:
277 divided by 68 is 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Deduct 272 from 277 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 68

Going ahead to step 5:
When dividing 50 by 68, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1240.0
The remainder is 50 after subtracting 0 from 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 68

Going ahead to step 6:
The number 68 fits into 509 7 times, leaving a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 12407.0
Deduct 476 from 509 and we're left 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.

On to step 7:
The number 68 fits into 330 4 times, leaving a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 12407.4
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.

Advancing to step 8:
580 divided by 68 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 12407.48
Subtract 544 from 580 to 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.

Advancing to step 9:
The number 68 fits into 360 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 12407.485
If we subtract 340 from 360, 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.

Moving on to step 10:
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: 12407.4852
If we subtract 136 from 200, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
640 divided by 68 is 9 with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 12407.48529
Subtract 612 from 640 to get 28.
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 12:
The number 68 fits into 280 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 12407.485294
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 13:
The number 68 fits into 80 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 12407.4852941
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.

Let's proceed to step 14:
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: 12407.48529411
Subtract 68 from 120 to get 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 12407.48529411 with a balance of 5.2e-08.
