We're dividing 455939 by 76 
The aim is to understand the frequency of 76 in 455939.

Step 1:
76 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 76

Advancing to step 2:
45 divided by 76 is 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 76

Let's proceed to step 3:
If we divide 455 by 76, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 380 from 455 to get 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 76

Step 4:
759 divided by 76 is 9 with a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtract 684 from 759 to get 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 76

Let's proceed to step 5:
If we divide 753 by 76, we get 9 and a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 599.0
The remainder is 69 after subtracting 684 from 753.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 76

Step 6:
76 can be fit into 699 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 5999.0
If we take 684 away from 699, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
If we divide 150 by 76, we get 1 and a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 5999.1
If we take 76 away from 150, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 8:
The number 76 fits into 740 9 times, leaving a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 5999.19
The remainder is 56 after subtracting 684 from 740.
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 9:
When dividing 560 by 76, we get 7 with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 5999.197
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.

Going ahead to step 10:
76 goes into 280 3 times with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 5999.1973
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.

Advancing to step 11:
76 goes into 520 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 5999.19736
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.

On to step 12:
76 goes into 640 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5999.197368
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.

Step 13:
76 can be fit into 320 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 5999.1973684
Subtract 304 from 320 to get 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 14:
76 can be fit into 160 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 5999.19736842
Deduct 152 from 160 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 5999.19736842, with a leftover of 8e-09.
