Let's divide 711405 by 28
The aim is to understand the frequency of 28 in 711405.

On to step 1:
When dividing 7 by 28, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 28

Step 2:
71 divided by 28 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 56 from 71 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 28

Let's proceed to step 3:
The number 28 fits into 151 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 140 from 151, we get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 28

Step 4:
When dividing 114 by 28, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
Subtract 112 from 114 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 28

Let's proceed to step 5:
28 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2540.0
If we subtract 0 from 20, we get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 28

Advancing to step 6:
If we divide 205 by 28, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 25407.0
Deduct 196 from 205 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 28, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 25407.3
Deduct 84 from 90 and we're left with 6.
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 8:
60 divided by 28 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 25407.32
Subtracting 56 from 60 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.

On to step 9:
28 goes into 40 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 25407.321
Deduct 28 from 40 and we're left 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.

On to step 10:
28 goes into 120 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 25407.3214
Deduct 112 from 120 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.

Step 11:
When dividing 80 by 28, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 25407.32142
If we take 56 away from 80, 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.

Let's proceed to step 12:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 25407.321428
If we take 224 away from 240, we end up 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.

On to step 13:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 25407.3214285
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.

On to step 14:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 25407.32142857
Deduct 196 from 200 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.

The quotient of the division is 25407.32142857, and the remainder is 4e-09.
