We're dividing 20857150 by 279 
The aim is to understand the frequency of 279 in 20857150.

Let's proceed to step 1:
If we divide 2 by 279, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 279

Going ahead to step 2:
The number 279 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 279

Step 3:
When dividing 208 by 279, we get 0 with a remainder of 208.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 208 and we're left with 208.
Append the next digit (5) from the dividend to 208 and continue with: 2085 / 279

Let's proceed to step 4:
279 can be fit into 2085 7 times, resulting in a remainder of 132.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 1953 from 2085, we get 132.
Take the next digit (7) from the dividend and append it to 132, then repeat: 1327 / 279

Advancing to step 5:
279 goes into 1327 4 times with a remainder of 211.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 211 after subtracting 1116 from 1327.
Include the next digit (1) from the dividend after 211, then repeat: 2111 / 279

Let's proceed to step 6:
When dividing 2111 by 279, we get 7 with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 747.0
If we subtract 1953 from 2111, we get 158.
Take the next digit (5) from the dividend and append it to 158, then repeat: 1585 / 279

Going ahead to step 7:
If we divide 1585 by 279, we get 5 and a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 7475.0
Subtract 1395 from 1585 to get 190.
Include the next digit (0) from the dividend after 190, then repeat: 1900 / 279

Advancing to step 8:
If we divide 1900 by 279, we get 6 and a remainder of 226.
Use 6 as the next digit of our solution. 
Result so far: 74756.0
Subtracting 1674 from 1900 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 9:
When dividing 2260 by 279, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 74756.8
If we subtract 2232 from 2260, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
If we divide 280 by 279, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 74756.81
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
10 divided by 279 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 74756.81
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
279 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 74756.81
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 74756.81 and a remainder of 0.001.
