186331 ÷ 68 
The aim is to understand the frequency of 68 in 186331.

Let's proceed to step 1:
The number 68 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 68

Let's proceed to step 2:
If we divide 18 by 68, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 68

Going ahead to step 3:
68 goes into 186 2 times with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 50 after subtracting 136 from 186.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 68

Step 4:
68 goes into 503 7 times with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 476 from 503, we get 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 68

Moving on to step 5:
273 divided by 68 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 274.0
Subtract 272 from 273 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 68

On to step 6:
11 divided by 68 is 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 2740.0
If we take 0 away from 11, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 68 fits into 110 1 times, leaving a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 2740.1
Deduct 68 from 110 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
When dividing 420 by 68, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 2740.16
The remainder is 12 after subtracting 408 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
120 divided by 68 is 1 with a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 2740.161
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.

On to step 10:
520 divided by 68 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 2740.1617
The remainder is 44 after subtracting 476 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
The number 68 fits into 440 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 2740.16176
Deduct 408 from 440 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
68 can be fit into 320 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 2740.161764
Subtracting 272 from 320 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
68 goes into 480 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 2740.1617647
If we take 476 away from 480, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
If we divide 40 by 68, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2740.1617647
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 2740.1617647, with a leftover of 4e-08.
