We divide 685175 by 28
The aim is to understand the frequency of 28 in 685175.

Going ahead to step 1:
6 divided by 28 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 28

Let's proceed to step 2:
The number 28 fits into 68 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 56 from 68 and we're left with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 28

Step 3:
If we divide 125 by 28, we get 4 and a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 112 from 125 to get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 28

Let's proceed to step 4:
28 goes into 131 4 times with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 244.0
Subtracting 112 from 131 leaves us with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 28

On to step 5:
The number 28 fits into 197 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 2447.0
Deduct 196 from 197 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 28

Going ahead to step 6:
15 divided by 28 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 24470.0
Deduct 0 from 15 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
28 can be fit into 150 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 24470.5
Deduct 140 from 150 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 28 is 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 24470.53
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 24470.535
Deduct 140 from 160 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.

Advancing to step 10:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 24470.5357
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
28 goes into 40 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 24470.53571
Subtract 28 from 40 to 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.

Advancing to step 12:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 24470.535714
If we take 112 away from 120, we end up 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.

Let's proceed to step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 24470.5357142
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:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 24470.53571428
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.

Our division results in 24470.53571428 with a remaining 1.6e-08.
