Let's divide 687436 by 28
The aim is to understand the frequency of 28 in 687436.

Let's proceed to step 1:
28 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 28

On to step 2:
If we divide 68 by 28, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 56 from 68, we get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 28

Let's proceed to step 3:
127 divided by 28 is 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 112 from 127 to get 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 28

Step 4:
154 divided by 28 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 245.0
Deduct 140 from 154 and we're left with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 28

Advancing to step 5:
28 can be fit into 143 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 2455.0
Subtract 140 from 143 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 28

Advancing to step 6:
28 goes into 36 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 24551.0
Subtract 28 from 36 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 7:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 24551.2
Subtract 56 from 80 to 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.

Going ahead to step 8:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 24551.28
Subtract 224 from 240 to 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.

On to step 9:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 24551.285
If we take 140 away from 160, we end up 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.

On to step 10:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 24551.2857
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.

On to step 11:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 24551.28571
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 12:
120 divided by 28 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 24551.285714
The remainder is 8 after subtracting 112 from 120.
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:
80 divided by 28 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 24551.2857142
Subtracting 56 from 80 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.

Going ahead to step 14:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 24551.28571428
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.

In conclusion, the division gives 24551.28571428 with a balance of 1.6e-08.
