Let's divide 39720662 by 279
The aim is to understand the frequency of 279 in 39720662.

Moving on to step 1:
If we divide 3 by 279, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 279

Advancing to step 2:
279 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 279

Let's proceed to step 3:
The number 279 fits into 397 1 times, leaving a remainder of 118.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 279 from 397 to get 118.
Append the next digit (2) from the dividend to 118 and continue with: 1182 / 279

Step 4:
If we divide 1182 by 279, we get 4 and a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 1116 from 1182 and we're left with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 279

On to step 5:
The number 279 fits into 660 2 times, leaving a remainder of 102.
Write down 2 as next digit of the result. 
Result so far: 142.0
Deduct 558 from 660 and we're left with 102.
Append the next digit (6) from the dividend to 102 and continue with: 1026 / 279

Advancing to step 6:
The number 279 fits into 1026 3 times, leaving a remainder of 189.
The number 3 becomes the next digit in our result. 
Result so far: 1423.0
The remainder is 189 after subtracting 837 from 1026.
Bring next digit (6) of the dividend behind the 189 and repeat the process: 1896 / 279

Going ahead to step 7:
The number 279 fits into 1896 6 times, leaving a remainder of 222.
Use 6 as the next digit of our solution. 
Result so far: 14236.0
If we subtract 1674 from 1896, we get 222.
Append the next digit (2) from the dividend to 222 and continue with: 2222 / 279

Let's proceed to step 8:
279 can be fit into 2222 7 times, resulting in a remainder of 269.
The number 7 becomes the next digit in our result. 
Result so far: 142367.0
If we take 1953 away from 2222, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Moving on to step 9:
The number 279 fits into 2690 9 times, leaving a remainder of 179.
Write down 9 as next digit of the result. 
Result so far: 142367.9
Subtracting 2511 from 2690 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 10:
279 can be fit into 1790 6 times, resulting in a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 142367.96
Subtracting 1674 from 1790 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 11:
279 can be fit into 1160 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 142367.964
Subtract 1116 from 1160 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
440 divided by 279 is 1 with a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 142367.9641
The remainder is 161 after subtracting 279 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 13:
279 can be fit into 1610 5 times, resulting in a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 142367.96415
The remainder is 215 after subtracting 1395 from 1610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 14:
2150 divided by 279 is 7 with a remainder of 197.
The next digit of our result is 7. 
Result so far: 142367.964157
The remainder is 197 after subtracting 1953 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 15:
The number 279 fits into 1970 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 142367.9641577
The remainder is 17 after subtracting 1953 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 142367.9641577 with a remainder of 1.7e-07.
