999139 ÷ 76 
The aim is to understand the frequency of 76 in 999139.

Step 1:
When dividing 9 by 76, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 76

Moving on to step 2:
99 divided by 76 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 76 from 99 and we're left with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 76

Advancing to step 3:
239 divided by 76 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 228 from 239, we get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 76

Moving on to step 4:
The number 76 fits into 111 1 times, leaving a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Subtract 76 from 111 to get 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 76

On to step 5:
When dividing 353 by 76, we get 4 with a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 1314.0
Deduct 304 from 353 and we're left with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 76

Step 6:
The number 76 fits into 499 6 times, leaving a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 13146.0
Subtract 456 from 499 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
If we divide 430 by 76, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 13146.5
Deduct 380 from 430 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
76 goes into 500 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 13146.56
Subtract 456 from 500 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.

On to step 9:
76 can be fit into 440 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 13146.565
Subtracting 380 from 440 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
If we divide 600 by 76, we get 7 and a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 13146.5657
Subtract 532 from 600 to 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.

Let's proceed to step 11:
The number 76 fits into 680 8 times, leaving a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 13146.56578
If we take 608 away from 680, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
76 goes into 720 9 times with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 13146.565789
The remainder is 36 after subtracting 684 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
360 divided by 76 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 13146.5657894
If we take 304 away from 360, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
76 can be fit into 560 7 times, resulting in a remainder of 28.
The next digit of our result is 7. 
Result so far: 13146.56578947
Deduct 532 from 560 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 13146.56578947 with a remaining 2.8e-08.
