We look at the division of 23161718 by 279 
The aim is to understand the frequency of 279 in 23161718.

Moving on to step 1:
279 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 279

Advancing to step 2:
When dividing 23 by 279, we get 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 279

Step 3:
279 goes into 231 0 times with a remainder of 231.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 231 and we're left with 231.
Fetch the next digit (6) from the dividend, attach it to 231 and continue: 2316 / 279

Let's proceed to step 4:
If we divide 2316 by 279, we get 8 and a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 2232 from 2316 and we're left with 84.
Grab the next digit (1) from the dividend, add it to 84, then carry on: 841 / 279

Moving on to step 5:
The number 279 fits into 841 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we take 837 away from 841, we end up with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 279

Moving on to step 6:
When dividing 47 by 279, we get 0 with a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 830.0
Deduct 0 from 47 and we're left with 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 279

Step 7:
When dividing 471 by 279, we get 1 with a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 8301.0
Subtract 279 from 471 to get 192.
Fetch the next digit (8) from the dividend, attach it to 192 and continue: 1928 / 279

Advancing to step 8:
1928 divided by 279 is 6 with a remainder of 254.
Use 6 as the next digit of our solution. 
Result so far: 83016.0
If we take 1674 away from 1928, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 9:
When dividing 2540 by 279, we get 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 83016.9
The remainder is 29 after subtracting 2511 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 10:
When dividing 290 by 279, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 83016.91
If we subtract 279 from 290, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
110 divided by 279 is 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 83016.91
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
If we divide 1100 by 279, we get 3 and a remainder of 263.
Write down 3 as next digit of the result. 
Result so far: 83016.9103
The remainder is 263 after subtracting 837 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 13:
2630 divided by 279 is 9 with a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 83016.91039
The remainder is 119 after subtracting 2511 from 2630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 14:
If we divide 1190 by 279, we get 4 and a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 83016.910394
If we take 1116 away from 1190, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 15:
When dividing 740 by 279, we get 2 with a remainder of 182.
Use 2 as the next digit of our solution. 
Result so far: 83016.9103942
Deduct 558 from 740 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 16:
When dividing 1820 by 279, we get 6 with a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 83016.91039426
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.

The final result is 83016.91039426 with a remainder of 1.46e-07.
