We look at the division of 47839993 by 279 
The aim is to understand the frequency of 279 in 47839993.

On to step 1:
If we divide 4 by 279, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 279

Let's proceed to step 2:
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: 0.0
Subtracting 0 from 47 leaves us with 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 279

Let's proceed to step 3:
279 can be fit into 478 1 times, resulting in a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 279 from 478 and we're left with 199.
Bring next digit (3) of the dividend behind the 199 and repeat the process: 1993 / 279

Going ahead to step 4:
1993 divided by 279 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 1953 from 1993 to get 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 279

Advancing to step 5:
When dividing 409 by 279, we get 1 with a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Subtract 279 from 409 to get 130.
Grab the next digit (9) from the dividend, add it to 130, then carry on: 1309 / 279

Step 6:
279 goes into 1309 4 times with a remainder of 193.
Use 4 as the next digit of our solution. 
Result so far: 1714.0
Subtracting 1116 from 1309 leaves us with 193.
Take the next digit (9) from the dividend and append it to 193, then repeat: 1939 / 279

Step 7:
279 can be fit into 1939 6 times, resulting in a remainder of 265.
The number 6 becomes the next digit in our result. 
Result so far: 17146.0
If we take 1674 away from 1939, we end up with 265.
Fetch the next digit (3) from the dividend, attach it to 265 and continue: 2653 / 279

Step 8:
2653 divided by 279 is 9 with a remainder of 142.
Record the quotient 9 as the next digit in the result. 
Result so far: 171469.0
The remainder is 142 after subtracting 2511 from 2653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 9:
1420 divided by 279 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 171469.5
Subtract 1395 from 1420 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
When dividing 250 by 279, we get 0 with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 171469.5
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 11:
2500 divided by 279 is 8 with a remainder of 268.
Record the quotient 8 as the next digit in the result. 
Result so far: 171469.508
Subtracting 2232 from 2500 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 12:
If we divide 2680 by 279, we get 9 and a remainder of 169.
Record the quotient 9 as the next digit in the result. 
Result so far: 171469.5089
The remainder is 169 after subtracting 2511 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

On to step 13:
279 goes into 1690 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 171469.50896
Subtracting 1674 from 1690 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
279 goes into 160 0 times with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 171469.50896
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
279 can be fit into 1600 5 times, resulting in a remainder of 205.
The next digit of our result is 5. 
Result so far: 171469.5089605
Deduct 1395 from 1600 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 16:
If we divide 2050 by 279, we get 7 and a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 171469.50896057
Subtracting 1953 from 2050 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

The final outcome is 171469.50896057, with a leftover of 9.7e-08.
