391813 ÷ 76 
The aim is to understand the frequency of 76 in 391813.

Moving on to step 1:
If we divide 3 by 76, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 76

Let's proceed to step 2:
76 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in 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

Moving on to step 3:
The number 76 fits into 391 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 380 from 391 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 76

Advancing to step 4:
When dividing 118 by 76, we get 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 51.0
If we take 76 away from 118, we end up with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 76

Step 5:
76 can be fit into 421 5 times, resulting in a remainder of 41.
The next digit of our result is 5. 
Result so far: 515.0
Subtract 380 from 421 to get 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 76

Let's proceed to step 6:
The number 76 fits into 413 5 times, leaving a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 5155.0
Subtracting 380 from 413 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
The number 76 fits into 330 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 5155.4
Subtract 304 from 330 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
If we divide 260 by 76, we get 3 and a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 5155.43
Subtracting 228 from 260 leaves us 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.

Advancing to step 9:
The number 76 fits into 320 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 5155.434
Subtracting 304 from 320 leaves us 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.

Going ahead to step 10:
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: 5155.4342
Subtract 152 from 160 to get 8.
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 11:
80 divided by 76 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 5155.43421
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
The number 76 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 5155.43421
If we subtract 0 from 40, 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.

Let's proceed to step 13:
The number 76 fits into 400 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 5155.4342105
Subtracting 380 from 400 leaves us 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.

Advancing to step 14:
76 can be fit into 200 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 5155.43421052
If we subtract 152 from 200, we 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.

After the division, we end up with 5155.43421052 and a remainder of 4.8e-08.
