We look at the division of 342936 by 76 
The aim is to understand the frequency of 76 in 342936.

Going ahead to step 1:
When dividing 3 by 76, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 76

Moving on to step 2:
76 can be fit into 34 0 times, resulting in a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 76

Step 3:
76 goes into 342 4 times with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 304 from 342 leaves us with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 76

On to step 4:
If we divide 389 by 76, we get 5 and a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 380 from 389 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 76

Going ahead to step 5:
When dividing 93 by 76, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 451.0
Deduct 76 from 93 and we're left with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 76

Advancing to step 6:
76 goes into 176 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 4512.0
If we take 152 away from 176, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
When dividing 240 by 76, we get 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 4512.3
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
120 divided by 76 is 1 with a remainder of 44.
The next digit of our result is 1. 
Result so far: 4512.31
Deduct 76 from 120 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.

Moving on to step 9:
The number 76 fits into 440 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 4512.315
If we take 380 away from 440, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
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: 4512.3157
Subtracting 532 from 600 leaves us 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.

On to step 11:
When dividing 680 by 76, we get 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 4512.31578
The remainder is 72 after subtracting 608 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
When dividing 720 by 76, we get 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 4512.315789
Subtracting 684 from 720 leaves us 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.

On to step 13:
The number 76 fits into 360 4 times, leaving a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 4512.3157894
If we subtract 304 from 360, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
76 can be fit into 560 7 times, resulting in a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 4512.31578947
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.

After the division, we end up with 4512.31578947 and a remainder of 2.8e-08.
