We're dividing 449853 by 79 
The aim is to understand the frequency of 79 in 449853.

Advancing to step 1:
The number 79 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 79

Moving on to step 2:
When dividing 44 by 79, we get 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 79

On to step 3:
The number 79 fits into 449 5 times, leaving a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 54 after subtracting 395 from 449.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 79

Going ahead to step 4:
If we divide 548 by 79, we get 6 and a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtract 474 from 548 to get 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 79

Moving on to step 5:
If we divide 745 by 79, we get 9 and a remainder of 34.
The next digit of our result is 9. 
Result so far: 569.0
If we subtract 711 from 745, we get 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 79

Advancing to step 6:
79 goes into 343 4 times with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 5694.0
Subtract 316 from 343 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 79, we get 3 and a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 5694.3
The remainder is 33 after subtracting 237 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 8:
330 divided by 79 is 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 5694.34
If we subtract 316 from 330, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
The number 79 fits into 140 1 times, leaving a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 5694.341
Deduct 79 from 140 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
610 divided by 79 is 7 with a remainder of 57.
The next digit of our result is 7. 
Result so far: 5694.3417
Subtract 553 from 610 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 11:
79 can be fit into 570 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 5694.34177
The remainder is 17 after subtracting 553 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 5694.34177 and a remainder of 1.7e-05.
