We're dividing 743353 by 79 
The aim is to understand the frequency of 79 in 743353.

On to step 1:
7 divided by 79 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 79

Let's proceed to step 2:
The number 79 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 79

Step 3:
79 goes into 743 9 times with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 32 after subtracting 711 from 743.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 79

Moving on to step 4:
79 goes into 323 4 times with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we subtract 316 from 323, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 79

Let's proceed to step 5:
When dividing 75 by 79, we get 0 with a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 940.0
The remainder is 75 after subtracting 0 from 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 79

Moving on to step 6:
The number 79 fits into 753 9 times, leaving a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 9409.0
If we subtract 711 from 753, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
79 can be fit into 420 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 9409.5
The remainder is 25 after subtracting 395 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
250 divided by 79 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 9409.53
The remainder is 13 after subtracting 237 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
If we divide 130 by 79, we get 1 and a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 9409.531
If we subtract 79 from 130, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 10:
When dividing 510 by 79, we get 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 9409.5316
Subtracting 474 from 510 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
If we divide 360 by 79, we get 4 and a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 9409.53164
If we subtract 316 from 360, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
The number 79 fits into 440 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 9409.531645
Subtracting 395 from 440 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
79 goes into 450 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 9409.5316455
Subtract 395 from 450 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 9409.5316455 and a remainder of 5.5e-07.
