We're dividing 138403 by 76 
The aim is to understand the frequency of 76 in 138403.

Let's proceed to step 1:
1 divided by 76 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 76

On to step 2:
76 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 76

On to step 3:
When dividing 138 by 76, we get 1 with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 76 from 138, we get 62.
Include the next digit (4) from the dividend after 62, then repeat: 624 / 76

Advancing to step 4:
When dividing 624 by 76, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 608 away from 624, we end up with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 76

Advancing to step 5:
76 can be fit into 160 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
If we subtract 152 from 160, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 76

Let's proceed to step 6:
If we divide 83 by 76, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1821.0
If we subtract 76 from 83, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 76 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 1821.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
The number 76 fits into 700 9 times, leaving a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 1821.09
Deduct 684 from 700 and we're left 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.

On to step 9:
The number 76 fits into 160 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 1821.092
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 76, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1821.0921
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 76 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1821.0921
Subtract 0 from 40 to 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.

Step 12:
76 goes into 400 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 1821.092105
If we take 380 away from 400, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
When dividing 200 by 76, we get 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 1821.0921052
Subtract 152 from 200 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
When dividing 480 by 76, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 1821.09210526
If we subtract 456 from 480, we 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.

In conclusion, the division gives 1821.09210526 with a balance of 2.4e-08.
