We divide 843684 by 79
The aim is to understand the frequency of 79 in 843684.

Let's proceed to step 1:
8 divided by 79 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 79

Moving on to step 2:
79 goes into 84 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 79 from 84 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 79

Advancing to step 3:
The number 79 fits into 53 0 times, leaving a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 79

Step 4:
79 goes into 536 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Deduct 474 from 536 and we're left with 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 79

On to step 5:
79 goes into 628 7 times with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 1067.0
The remainder is 75 after subtracting 553 from 628.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 79

Advancing to step 6:
79 goes into 754 9 times with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 10679.0
Subtracting 711 from 754 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
79 can be fit into 430 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 10679.5
Subtracting 395 from 430 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
If we divide 350 by 79, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 10679.54
Subtract 316 from 350 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
340 divided by 79 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 10679.544
Subtracting 316 from 340 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 10679.544, and the remainder is 0.0024.
