We look at the division of 157122 by 28 
The aim is to understand the frequency of 28 in 157122.

Moving on to step 1:
28 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 28

On to step 2:
15 divided by 28 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 28

Advancing to step 3:
If we divide 157 by 28, we get 5 and a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 140 away from 157, we end up with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 28

Advancing to step 4:
28 can be fit into 171 6 times, resulting in a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtract 168 from 171 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 28

Step 5:
28 can be fit into 32 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 561.0
The remainder is 4 after subtracting 28 from 32.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 28

Advancing to step 6:
28 goes into 42 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 5611.0
If we take 28 away from 42, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
If we divide 140 by 28, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5611.5
The remainder is 0 after subtracting 140 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 28, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5611.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 28 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5611.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 5611.5, and the remainder is 0.0.
