We look at the division of 21286970 by 76 
The aim is to understand the frequency of 76 in 21286970.

Going ahead to step 1:
2 divided by 76 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 76

Step 2:
76 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 76

Going ahead to step 3:
212 divided by 76 is 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 152 from 212 and we're left with 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 76

Let's proceed to step 4:
The number 76 fits into 608 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 608 away from 608, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 76

On to step 5:
If we divide 6 by 76, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 280.0
Subtract 0 from 6 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 76

Advancing to step 6:
If we divide 69 by 76, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 2800.0
Subtract 0 from 69 to get 69.
Include the next digit (7) from the dividend after 69, then repeat: 697 / 76

Let's proceed to step 7:
If we divide 697 by 76, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 28009.0
If we subtract 684 from 697, we get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 76

Advancing to step 8:
The number 76 fits into 130 1 times, leaving a remainder of 54.
The next digit of our result is 1. 
Result so far: 280091.0
If we take 76 away from 130, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 9:
When dividing 540 by 76, we get 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 280091.7
The remainder is 8 after subtracting 532 from 540.
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 10:
76 can be fit into 80 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 280091.71
Subtract 76 from 80 to 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.

Advancing to step 11:
76 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 280091.71
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
76 goes into 400 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 280091.7105
If we subtract 380 from 400, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
If we divide 200 by 76, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 280091.71052
Subtract 152 from 200 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
If we divide 480 by 76, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 280091.710526
Subtracting 456 from 480 leaves us 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.

Advancing to step 15:
If we divide 240 by 76, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 280091.7105263
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.

Step 16:
When dividing 120 by 76, we get 1 with a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 280091.71052631
The remainder is 44 after subtracting 76 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 280091.71052631 with a balance of 4.4e-08.
