705816 divided by 28 
The aim is to understand the frequency of 28 in 705816.

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.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 28

Step 2:
70 divided by 28 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 56 from 70, we get 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 28

Going ahead to step 3:
If we divide 145 by 28, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 140 from 145 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 28

On to step 4:
58 divided by 28 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 252.0
If we subtract 56 from 58, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 28

Going ahead to step 5:
When dividing 21 by 28, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 2520.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 28

Let's proceed to step 6:
The number 28 fits into 216 7 times, leaving a remainder of 20.
The next digit of our result is 7. 
Result so far: 25207.0
Deduct 196 from 216 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
If we divide 200 by 28, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 25207.7
Subtract 196 from 200 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 8:
40 divided by 28 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 25207.71
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 28 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 25207.714
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.

Moving on to step 10:
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: 25207.7142
Deduct 56 from 80 and we're left 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.

Step 11:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 25207.71428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 25207.714285
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.

Advancing to step 13:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 25207.7142857
If we subtract 196 from 200, 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.

On to step 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 25207.71428571
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 25207.71428571 with a balance of 1.2e-08.
