We're dividing 303186 by 76 
The aim is to understand the frequency of 76 in 303186.

Going ahead to step 1:
76 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 76

Moving on to step 2:
When dividing 30 by 76, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 76

Advancing to step 3:
76 can be fit into 303 3 times, resulting in a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 228 from 303 and we're left with 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 76

Moving on to step 4:
The number 76 fits into 751 9 times, leaving a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 684 from 751 leaves us with 67.
Fetch the next digit (8) from the dividend, attach it to 67 and continue: 678 / 76

Advancing to step 5:
If we divide 678 by 76, we get 8 and a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 398.0
Deduct 608 from 678 and we're left with 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 76

Advancing to step 6:
76 goes into 706 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 3989.0
The remainder is 22 after subtracting 684 from 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
76 can be fit into 220 2 times, resulting in a remainder of 68.
The next digit of our result is 2. 
Result so far: 3989.2
Deduct 152 from 220 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
If we divide 680 by 76, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 3989.28
Subtracting 608 from 680 leaves us 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 9:
720 divided by 76 is 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 3989.289
If we take 684 away from 720, we end up with 36.
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 10:
360 divided by 76 is 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 3989.2894
Deduct 304 from 360 and we're left 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.

On to step 11:
If we divide 560 by 76, we get 7 and a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 3989.28947
Subtract 532 from 560 to 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.

Moving on to step 12:
When dividing 280 by 76, we get 3 with a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 3989.289473
Subtracting 228 from 280 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
76 goes into 520 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 3989.2894736
Subtracting 456 from 520 leaves us 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.

Step 14:
76 goes into 640 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 3989.28947368
Subtract 608 from 640 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 3989.28947368, and the remainder is 3.2e-08.
