155485 ÷ 68 
The aim is to understand the frequency of 68 in 155485.

Advancing to step 1:
When dividing 1 by 68, we get 0 with 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.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 68

Step 2:
15 divided by 68 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 68

On to step 3:
155 divided by 68 is 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 136 from 155, we get 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 68

Going ahead to step 4:
68 goes into 194 2 times with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 136 from 194, we get 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 68

Let's proceed to step 5:
The number 68 fits into 588 8 times, leaving a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 228.0
Subtract 544 from 588 to get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 68

Going ahead to step 6:
68 goes into 445 6 times with a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 2286.0
Deduct 408 from 445 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
The number 68 fits into 370 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 2286.5
Subtract 340 from 370 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
68 goes into 300 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 2286.54
Subtract 272 from 300 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.

Advancing to step 9:
If we divide 280 by 68, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 2286.544
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.

Our division results in 2286.544 with a remaining 0.0008.
