428373 divided by 76 
The aim is to understand the frequency of 76 in 428373.

On to step 1:
When dividing 4 by 76, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 76

Moving on to step 2:
When dividing 42 by 76, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 76

Step 3:
76 goes into 428 5 times with a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 380 from 428 to get 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 76

Moving on to step 4:
76 can be fit into 483 6 times, resulting in a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 56.0
The remainder is 27 after subtracting 456 from 483.
Include the next digit (7) from the dividend after 27, then repeat: 277 / 76

Let's proceed to step 5:
76 can be fit into 277 3 times, resulting in a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 563.0
Subtracting 228 from 277 leaves us with 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 76

On to step 6:
76 can be fit into 493 6 times, resulting in a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 5636.0
Deduct 456 from 493 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
76 can be fit into 370 4 times, resulting in a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 5636.4
Deduct 304 from 370 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 8:
76 can be fit into 660 8 times, resulting in a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 5636.48
Subtract 608 from 660 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.

Step 9:
When dividing 520 by 76, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 5636.486
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 10:
If we divide 640 by 76, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 5636.4868
If we subtract 608 from 640, we 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.

Moving on to step 11:
76 can be fit into 320 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 5636.48684
The remainder is 16 after subtracting 304 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
76 can be fit into 160 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 5636.486842
Subtracting 152 from 160 leaves us 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.

On to step 13:
If we divide 80 by 76, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 5636.4868421
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
76 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 5636.4868421
Subtract 0 from 40 to 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.

The final result is 5636.4868421 with a remainder of 4e-08.
