Let's divide 345666 by 68
The aim is to understand the frequency of 68 in 345666.

Moving on to step 1:
When dividing 3 by 68, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 68

Moving on to step 2:
68 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 68

On to step 3:
345 divided by 68 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 340 from 345 leaves us with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 68

On to step 4:
68 can be fit into 56 0 times, resulting in a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 56 to get 56.
Fetch the next digit (6) from the dividend, attach it to 56 and continue: 566 / 68

Step 5:
566 divided by 68 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 508.0
If we subtract 544 from 566, we get 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 68

Going ahead to step 6:
68 can be fit into 226 3 times, resulting in a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 5083.0
The remainder is 22 after subtracting 204 from 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
When dividing 220 by 68, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 5083.3
If we take 204 away from 220, we end up 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.

Step 8:
68 can be fit into 160 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 5083.32
Subtract 136 from 160 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
240 divided by 68 is 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 5083.323
Subtracting 204 from 240 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
360 divided by 68 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 5083.3235
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.

Advancing to step 11:
The number 68 fits into 200 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 5083.32352
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.

Advancing to step 12:
68 can be fit into 640 9 times, resulting in a remainder of 28.
The next digit of our result is 9. 
Result so far: 5083.323529
If we subtract 612 from 640, we 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.

Moving on to step 13:
If we divide 280 by 68, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 5083.3235294
If we subtract 272 from 280, we get 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 14:
80 divided by 68 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 5083.32352941
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 5083.32352941, with a leftover of 1.2e-08.
