We're dividing 609359 by 79 
The aim is to understand the frequency of 79 in 609359.

Going ahead to step 1:
The number 79 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 79

On to step 2:
60 divided by 79 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 79

Going ahead to step 3:
79 can be fit into 609 7 times, resulting in a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 553 away from 609, we end up with 56.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 79

On to step 4:
563 divided by 79 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Deduct 553 from 563 and we're left with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 79

Advancing to step 5:
105 divided by 79 is 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 771.0
If we take 79 away from 105, we end up with 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 79

Going ahead to step 6:
79 can be fit into 269 3 times, resulting in a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 7713.0
Deduct 237 from 269 and we're left 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 7:
If we divide 320 by 79, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 7713.4
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.

Moving on to step 8:
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: 7713.4
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 9:
The number 79 fits into 400 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 7713.405
Subtract 395 from 400 to 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.

Going ahead to step 10:
The number 79 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7713.405
Subtract 0 from 50 to 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.

Advancing to step 11:
500 divided by 79 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 7713.40506
The remainder is 26 after subtracting 474 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
260 divided by 79 is 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 7713.405063
Subtracting 237 from 260 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
230 divided by 79 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 7713.4050632
If we take 158 away from 230, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
720 divided by 79 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 7713.40506329
Subtracting 711 from 720 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 7713.40506329 with a remainder of 9e-09.
