We're dividing 503986 by 79 
The aim is to understand the frequency of 79 in 503986.

Advancing to step 1:
79 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 79

Step 2:
When dividing 50 by 79, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 79

On to step 3:
503 divided by 79 is 6 with a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 474 away from 503, we end up with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 79

Going ahead to step 4:
79 can be fit into 299 3 times, resulting in a remainder of 62.
The next digit of our result is 3. 
Result so far: 63.0
If we take 237 away from 299, we end up with 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 79

Let's proceed to step 5:
When dividing 628 by 79, we get 7 with a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 637.0
Subtracting 553 from 628 leaves us with 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 79

Going ahead to step 6:
756 divided by 79 is 9 with a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 6379.0
If we subtract 711 from 756, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
If we divide 450 by 79, we get 5 and a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 6379.5
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.

Advancing to step 8:
79 can be fit into 550 6 times, resulting in a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 6379.56
Subtract 474 from 550 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
When dividing 760 by 79, we get 9 with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 6379.569
If we take 711 away from 760, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
490 divided by 79 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 6379.5696
If we take 474 away from 490, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
If we divide 160 by 79, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 6379.56962
The remainder is 2 after subtracting 158 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
The number 79 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6379.56962
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
200 divided by 79 is 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 6379.5696202
Subtract 158 from 200 to 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.

Advancing to step 14:
When dividing 420 by 79, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6379.56962025
Subtract 395 from 420 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 6379.56962025 with a remaining 2.5e-08.
