We're dividing 72876745 by 279 
The aim is to understand the frequency of 279 in 72876745.

Step 1:
7 divided by 279 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 279

On to step 2:
72 divided by 279 is 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 279

Going ahead to step 3:
The number 279 fits into 728 2 times, leaving a remainder of 170.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 558 from 728 to get 170.
Take the next digit (7) from the dividend and append it to 170, then repeat: 1707 / 279

Let's proceed to step 4:
279 goes into 1707 6 times with a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 33 after subtracting 1674 from 1707.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 279

Advancing to step 5:
279 goes into 336 1 times with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 261.0
Subtracting 279 from 336 leaves us with 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 279

Advancing to step 6:
279 can be fit into 577 2 times, resulting in a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2612.0
Subtract 558 from 577 to get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 279

Let's proceed to step 7:
279 can be fit into 194 0 times, resulting in a remainder of 194.
Record the quotient 0 as the next digit in the result. 
Result so far: 26120.0
Subtract 0 from 194 to get 194.
Grab the next digit (5) from the dividend, add it to 194, then carry on: 1945 / 279

Going ahead to step 8:
279 can be fit into 1945 6 times, resulting in a remainder of 271.
Use 6 as the next digit of our solution. 
Result so far: 261206.0
If we subtract 1674 from 1945, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 9:
2710 divided by 279 is 9 with a remainder of 199.
The number 9 becomes the next digit in our result. 
Result so far: 261206.9
Deduct 2511 from 2710 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 10:
When dividing 1990 by 279, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 261206.97
The remainder is 37 after subtracting 1953 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
279 can be fit into 370 1 times, resulting in a remainder of 91.
The next digit of our result is 1. 
Result so far: 261206.971
Deduct 279 from 370 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 12:
If we divide 910 by 279, we get 3 and a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 261206.9713
The remainder is 73 after subtracting 837 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 13:
When dividing 730 by 279, we get 2 with a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 261206.97132
If we take 558 away from 730, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 14:
If we divide 1720 by 279, we get 6 and a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 261206.971326
Subtract 1674 from 1720 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 15:
279 can be fit into 460 1 times, resulting in a remainder of 181.
The next digit of our result is 1. 
Result so far: 261206.9713261
Subtract 279 from 460 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 16:
The number 279 fits into 1810 6 times, leaving a remainder of 136.
Write down 6 as next digit of the result. 
Result so far: 261206.97132616
Subtracting 1674 from 1810 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 261206.97132616 and a remainder of 1.36e-07.
