Let's divide 77141927 by 28
The aim is to understand the frequency of 28 in 77141927.

Going ahead to step 1:
When dividing 7 by 28, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 28

Going ahead to step 2:
The number 28 fits into 77 2 times, leaving a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 21 after subtracting 56 from 77.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 28

Going ahead to step 3:
28 can be fit into 211 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 196 from 211, we get 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 28

Let's proceed to step 4:
28 can be fit into 154 5 times, resulting in a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 275.0
Deduct 140 from 154 and we're left with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 28

On to step 5:
If we divide 141 by 28, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 2755.0
Deduct 140 from 141 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 28

On to step 6:
19 divided by 28 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 27550.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 28

Moving on to step 7:
The number 28 fits into 192 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 275506.0
Subtract 168 from 192 to get 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 28

Going ahead to step 8:
28 goes into 247 8 times with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 2755068.0
If we take 224 away from 247, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
28 can be fit into 230 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 2755068.8
The remainder is 6 after subtracting 224 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
28 goes into 60 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2755068.82
Deduct 56 from 60 and we're left with 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:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 2755068.821
Subtracting 28 from 40 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.

Advancing to step 12:
When dividing 120 by 28, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 2755068.8214
Subtract 112 from 120 to get 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:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2755068.82142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 2755068.821428
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 15:
If we divide 160 by 28, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 2755068.8214285
If we subtract 140 from 160, 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.

Step 16:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 2755068.82142857
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 2755068.82142857, with a leftover of 4e-09.
