136789 ÷ 76 
The aim is to understand the frequency of 76 in 136789.

Step 1:
If we divide 1 by 76, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 76

Let's proceed to step 2:
76 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 76

Let's proceed to step 3:
The number 76 fits into 136 1 times, leaving a remainder of 60.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 76 from 136 leaves us with 60.
Append the next digit (7) from the dividend to 60 and continue with: 607 / 76

Advancing to step 4:
607 divided by 76 is 7 with a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 532 from 607 leaves us with 75.
Fetch the next digit (8) from the dividend, attach it to 75 and continue: 758 / 76

Let's proceed to step 5:
76 can be fit into 758 9 times, resulting in a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 179.0
The remainder is 74 after subtracting 684 from 758.
Include the next digit (9) from the dividend after 74, then repeat: 749 / 76

Step 6:
76 goes into 749 9 times with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 1799.0
Subtracting 684 from 749 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
If we divide 650 by 76, we get 8 and a remainder of 42.
The next digit of our result is 8. 
Result so far: 1799.8
Subtracting 608 from 650 leaves us 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.

Advancing to step 8:
If we divide 420 by 76, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1799.85
If we subtract 380 from 420, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 76 fits into 400 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 1799.855
If we subtract 380 from 400, 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.

After the division, we end up with 1799.855 and a remainder of 0.002.
