We're dividing 853369 by 79 
The aim is to understand the frequency of 79 in 853369.

Let's proceed to step 1:
When dividing 8 by 79, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 79

Advancing to step 2:
The number 79 fits into 85 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 79 from 85, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 79

On to step 3:
If we divide 63 by 79, we get 0 and a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 63, we get 63.
Fetch the next digit (3) from the dividend, attach it to 63 and continue: 633 / 79

Moving on to step 4:
The number 79 fits into 633 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Subtracting 632 from 633 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 79

Moving on to step 5:
16 divided by 79 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 1080.0
If we subtract 0 from 16, we get 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 79

Let's proceed to step 6:
79 goes into 169 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 10802.0
Subtract 158 from 169 to 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.

On to step 7:
79 goes into 110 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 10802.1
Subtracting 79 from 110 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
79 goes into 310 3 times with a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 10802.13
If we take 237 away from 310, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 9:
If we divide 730 by 79, we get 9 and a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 10802.139
Deduct 711 from 730 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
79 goes into 190 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 10802.1392
If we take 158 away from 190, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
320 divided by 79 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 10802.13924
Subtracting 316 from 320 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
If we divide 40 by 79, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10802.13924
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
If we divide 400 by 79, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 10802.1392405
If we subtract 395 from 400, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
79 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10802.1392405
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 10802.1392405 with a remaining 5e-08.
