We're dividing 28671349 by 170 
The aim is to understand the frequency of 170 in 28671349.

Let's proceed to step 1:
If we divide 2 by 170, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 170

Step 2:
170 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 170

Moving on to step 3:
The number 170 fits into 286 1 times, leaving a remainder of 116.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 170 from 286 leaves us with 116.
Bring next digit (7) of the dividend behind the 116 and repeat the process: 1167 / 170

On to step 4:
1167 divided by 170 is 6 with a remainder of 147.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 147 after subtracting 1020 from 1167.
Bring next digit (1) of the dividend behind the 147 and repeat the process: 1471 / 170

Advancing to step 5:
1471 divided by 170 is 8 with a remainder of 111.
Use 8 as the next digit of our solution. 
Result so far: 168.0
The remainder is 111 after subtracting 1360 from 1471.
Take the next digit (3) from the dividend and append it to 111, then repeat: 1113 / 170

On to step 6:
If we divide 1113 by 170, we get 6 and a remainder of 93.
Use 6 as the next digit of our solution. 
Result so far: 1686.0
If we subtract 1020 from 1113, we get 93.
Include the next digit (4) from the dividend after 93, then repeat: 934 / 170

On to step 7:
The number 170 fits into 934 5 times, leaving a remainder of 84.
The number 5 becomes the next digit in our result. 
Result so far: 16865.0
If we subtract 850 from 934, we get 84.
Append the next digit (9) from the dividend to 84 and continue with: 849 / 170

Going ahead to step 8:
When dividing 849 by 170, we get 4 with a remainder of 169.
The next digit of our result is 4. 
Result so far: 168654.0
Subtracting 680 from 849 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 9:
When dividing 1690 by 170, we get 9 with a remainder of 160.
Record the quotient 9 as the next digit in the result. 
Result so far: 168654.9
Subtracting 1530 from 1690 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
If we divide 1600 by 170, we get 9 and a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 168654.99
If we subtract 1530 from 1600, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 168654.99 with a remainder of 0.07.
