We look at the division of 78316867 by 579 
The aim is to understand the frequency of 579 in 78316867.

Step 1:
579 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 579

Moving on to step 2:
When dividing 78 by 579, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 579

Let's proceed to step 3:
579 goes into 783 1 times with a remainder of 204.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 579 from 783 and we're left with 204.
Include the next digit (1) from the dividend after 204, then repeat: 2041 / 579

Advancing to step 4:
The number 579 fits into 2041 3 times, leaving a remainder of 304.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1737 away from 2041, we end up with 304.
Append the next digit (6) from the dividend to 304 and continue with: 3046 / 579

Step 5:
When dividing 3046 by 579, we get 5 with a remainder of 151.
The next digit of our result is 5. 
Result so far: 135.0
Subtract 2895 from 3046 to get 151.
Bring next digit (8) of the dividend behind the 151 and repeat the process: 1518 / 579

On to step 6:
If we divide 1518 by 579, we get 2 and a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 1352.0
If we subtract 1158 from 1518, we get 360.
Include the next digit (6) from the dividend after 360, then repeat: 3606 / 579

Let's proceed to step 7:
The number 579 fits into 3606 6 times, leaving a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 13526.0
Subtract 3474 from 3606 to get 132.
Append the next digit (7) from the dividend to 132 and continue with: 1327 / 579

Let's proceed to step 8:
When dividing 1327 by 579, we get 2 with a remainder of 169.
The next digit of our result is 2. 
Result so far: 135262.0
Deduct 1158 from 1327 and we're left with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

On to step 9:
579 can be fit into 1690 2 times, resulting in a remainder of 532.
Put 2 as the next digit of the answer. 
Result so far: 135262.2
The remainder is 532 after subtracting 1158 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 10:
579 can be fit into 5320 9 times, resulting in a remainder of 109.
Write down 9 as next digit of the result. 
Result so far: 135262.29
If we take 5211 away from 5320, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 11:
1090 divided by 579 is 1 with a remainder of 511.
Record the quotient 1 as the next digit in the result. 
Result so far: 135262.291
Subtract 579 from 1090 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Moving on to step 12:
When dividing 5110 by 579, we get 8 with a remainder of 478.
The number 8 becomes the next digit in our result. 
Result so far: 135262.2918
If we subtract 4632 from 5110, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Let's proceed to step 13:
4780 divided by 579 is 8 with a remainder of 148.
The next digit of our result is 8. 
Result so far: 135262.29188
Subtracting 4632 from 4780 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The quotient of the division is 135262.29188, and the remainder is 0.000148.
