We look at the division of 403078 by 76 
The aim is to understand the frequency of 76 in 403078.

On to step 1:
If we divide 4 by 76, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 76

Step 2:
40 divided by 76 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 76

Step 3:
When dividing 403 by 76, we get 5 with a remainder of 23.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 380 from 403 to get 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 76

Step 4:
76 can be fit into 230 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 53.0
Deduct 228 from 230 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 76

Going ahead to step 5:
76 goes into 27 0 times with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 530.0
Deduct 0 from 27 and we're left with 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 76

Moving on to step 6:
The number 76 fits into 278 3 times, leaving a remainder of 50.
The next digit of our result is 3. 
Result so far: 5303.0
Subtracting 228 from 278 leaves us 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.

On to step 7:
76 goes into 500 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 5303.6
Deduct 456 from 500 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
The number 76 fits into 440 5 times, leaving a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 5303.65
Subtract 380 from 440 to 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.

On to step 9:
When dividing 600 by 76, we get 7 with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 5303.657
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.

On to step 10:
76 goes into 680 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 5303.6578
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 11:
720 divided by 76 is 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 5303.65789
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.

Going ahead to step 12:
76 goes into 360 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 5303.657894
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.

Step 13:
76 goes into 560 7 times with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 5303.6578947
The remainder is 28 after subtracting 532 from 560.
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 14:
76 can be fit into 280 3 times, resulting in a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 5303.65789473
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.

The final outcome is 5303.65789473, with a leftover of 5.2e-08.
