We divide 67709616 by 135
The aim is to understand the frequency of 135 in 67709616.

On to step 1:
6 divided by 135 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 135

Going ahead to step 2:
If we divide 67 by 135, we get 0 and a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Bring next digit (7) of the dividend behind the 67 and repeat the process: 677 / 135

On to step 3:
677 divided by 135 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 675 from 677 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 135

Advancing to step 4:
If we divide 20 by 135, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 20 to get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 135

Step 5:
135 goes into 209 1 times with a remainder of 74.
The next digit of our result is 1. 
Result so far: 501.0
Deduct 135 from 209 and we're left with 74.
Fetch the next digit (6) from the dividend, attach it to 74 and continue: 746 / 135

Advancing to step 6:
When dividing 746 by 135, we get 5 with a remainder of 71.
Put 5 as the next digit of the answer. 
Result so far: 5015.0
Deduct 675 from 746 and we're left with 71.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 135

Let's proceed to step 7:
135 goes into 711 5 times with a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 50155.0
Deduct 675 from 711 and we're left with 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 135

Let's proceed to step 8:
366 divided by 135 is 2 with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 501552.0
The remainder is 96 after subtracting 270 from 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 9:
If we divide 960 by 135, we get 7 and a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 501552.7
If we subtract 945 from 960, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
If we divide 150 by 135, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 501552.71
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
If we divide 150 by 135, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 501552.711
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 501552.711 and a remainder of 0.0015.
