Let's divide 391911 by 76
The aim is to understand the frequency of 76 in 391911.

Advancing to step 1:
3 divided by 76 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 76

Step 2:
39 divided by 76 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 76

Let's proceed to step 3:
When dividing 391 by 76, we get 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 380 from 391 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 76

Advancing to step 4:
When dividing 119 by 76, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
The remainder is 43 after subtracting 76 from 119.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 76

Advancing to step 5:
If we divide 431 by 76, we get 5 and a remainder of 51.
Write down 5 as next digit of the result. 
Result so far: 515.0
The remainder is 51 after subtracting 380 from 431.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 76

Let's proceed to step 6:
76 can be fit into 511 6 times, resulting in a remainder of 55.
The next digit of our result is 6. 
Result so far: 5156.0
If we take 456 away from 511, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
550 divided by 76 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 5156.7
If we take 532 away from 550, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
When dividing 180 by 76, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 5156.72
If we subtract 152 from 180, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
280 divided by 76 is 3 with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 5156.723
Subtract 228 from 280 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
When dividing 520 by 76, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 5156.7236
Deduct 456 from 520 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
76 can be fit into 640 8 times, resulting in a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5156.72368
If we take 608 away from 640, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
If we divide 320 by 76, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 5156.723684
If we take 304 away from 320, we end up 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.

Moving on to step 13:
When dividing 160 by 76, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 5156.7236842
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.

On to step 14:
76 can be fit into 80 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 5156.72368421
Deduct 76 from 80 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 5156.72368421 with a remaining 4e-09.
