We divide 27201566 by 279
The aim is to understand the frequency of 279 in 27201566.

Step 1:
When dividing 2 by 279, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 279

Advancing to step 2:
If we divide 27 by 279, we get 0 and a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 279

Step 3:
When dividing 272 by 279, we get 0 with a remainder of 272.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 272, we end up with 272.
Include the next digit (0) from the dividend after 272, then repeat: 2720 / 279

Moving on to step 4:
When dividing 2720 by 279, we get 9 with a remainder of 209.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 209 after subtracting 2511 from 2720.
Append the next digit (1) from the dividend to 209 and continue with: 2091 / 279

Going ahead to step 5:
When dividing 2091 by 279, we get 7 with a remainder of 138.
The next digit of our result is 7. 
Result so far: 97.0
Deduct 1953 from 2091 and we're left with 138.
Append the next digit (5) from the dividend to 138 and continue with: 1385 / 279

Step 6:
When dividing 1385 by 279, we get 4 with a remainder of 269.
Record the quotient 4 as the next digit in the result. 
Result so far: 974.0
The remainder is 269 after subtracting 1116 from 1385.
Fetch the next digit (6) from the dividend, attach it to 269 and continue: 2696 / 279

On to step 7:
If we divide 2696 by 279, we get 9 and a remainder of 185.
Record the quotient 9 as the next digit in the result. 
Result so far: 9749.0
The remainder is 185 after subtracting 2511 from 2696.
Include the next digit (6) from the dividend after 185, then repeat: 1856 / 279

Advancing to step 8:
If we divide 1856 by 279, we get 6 and a remainder of 182.
Put 6 as the next digit of the answer. 
Result so far: 97496.0
Deduct 1674 from 1856 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 9:
279 goes into 1820 6 times with a remainder of 146.
Put 6 as the next digit of the answer. 
Result so far: 97496.6
The remainder is 146 after subtracting 1674 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 10:
1460 divided by 279 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 97496.65
Subtracting 1395 from 1460 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
279 can be fit into 650 2 times, resulting in a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 97496.652
The remainder is 92 after subtracting 558 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 12:
279 goes into 920 3 times with a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 97496.6523
If we subtract 837 from 920, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 13:
When dividing 830 by 279, we get 2 with a remainder of 272.
The next digit of our result is 2. 
Result so far: 97496.65232
Subtracting 558 from 830 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 14:
The number 279 fits into 2720 9 times, leaving a remainder of 209.
Use 9 as the next digit of our solution. 
Result so far: 97496.652329
If we take 2511 away from 2720, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 15:
The number 279 fits into 2090 7 times, leaving a remainder of 137.
The number 7 becomes the next digit in our result. 
Result so far: 97496.6523297
Deduct 1953 from 2090 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 16:
If we divide 1370 by 279, we get 4 and a remainder of 254.
Use 4 as the next digit of our solution. 
Result so far: 97496.65232974
The remainder is 254 after subtracting 1116 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The quotient of the division is 97496.65232974, and the remainder is 2.54e-07.
