We look at the division of 438999 by 76 
The aim is to understand the frequency of 76 in 438999.

Step 1:
If we divide 4 by 76, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 76

Going ahead to step 2:
76 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 76

Advancing to step 3:
If we divide 438 by 76, we get 5 and a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 380 away from 438, we end up with 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 76

Step 4:
589 divided by 76 is 7 with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Deduct 532 from 589 and we're left with 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 76

Advancing to step 5:
76 can be fit into 579 7 times, resulting in a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 577.0
Deduct 532 from 579 and we're left with 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 76

Going ahead to step 6:
479 divided by 76 is 6 with a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 5776.0
Subtract 456 from 479 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
The number 76 fits into 230 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 5776.3
Deduct 228 from 230 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
76 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5776.3
Subtract 0 from 20 to 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.

Going ahead to step 9:
When dividing 200 by 76, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 5776.302
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.

Going ahead to step 10:
When dividing 480 by 76, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 5776.3026
Subtract 456 from 480 to 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.

Moving on to step 11:
The number 76 fits into 240 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 5776.30263
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
76 can be fit into 120 1 times, resulting in a remainder of 44.
The next digit of our result is 1. 
Result so far: 5776.302631
Subtract 76 from 120 to get 44.
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 13:
When dividing 440 by 76, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 5776.3026315
If we subtract 380 from 440, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
76 can be fit into 600 7 times, resulting in a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 5776.30263157
If we subtract 532 from 600, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 5776.30263157 and a remainder of 6.8e-08.
