We look at the division of 79138233 by 578 
The aim is to understand the frequency of 578 in 79138233.

On to step 1:
578 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 578

On to step 2:
578 can be fit into 79 0 times, resulting in a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 578

Step 3:
578 goes into 791 1 times with a remainder of 213.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 578 from 791 leaves us with 213.
Bring next digit (3) of the dividend behind the 213 and repeat the process: 2133 / 578

Let's proceed to step 4:
When dividing 2133 by 578, we get 3 with a remainder of 399.
The next digit of our result is 3. 
Result so far: 13.0
If we take 1734 away from 2133, we end up with 399.
Grab the next digit (8) from the dividend, add it to 399, then carry on: 3998 / 578

Advancing to step 5:
578 goes into 3998 6 times with a remainder of 530.
The next digit of our result is 6. 
Result so far: 136.0
Subtract 3468 from 3998 to get 530.
Take the next digit (2) from the dividend and append it to 530, then repeat: 5302 / 578

Going ahead to step 6:
578 can be fit into 5302 9 times, resulting in a remainder of 100.
Record the quotient 9 as the next digit in the result. 
Result so far: 1369.0
If we subtract 5202 from 5302, we get 100.
Append the next digit (3) from the dividend to 100 and continue with: 1003 / 578

Moving on to step 7:
1003 divided by 578 is 1 with a remainder of 425.
The number 1 becomes the next digit in our result. 
Result so far: 13691.0
If we take 578 away from 1003, we end up with 425.
Include the next digit (3) from the dividend after 425, then repeat: 4253 / 578

Advancing to step 8:
578 can be fit into 4253 7 times, resulting in a remainder of 207.
Record the quotient 7 as the next digit in the result. 
Result so far: 136917.0
Deduct 4046 from 4253 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 9:
If we divide 2070 by 578, we get 3 and a remainder of 336.
Put 3 as the next digit of the answer. 
Result so far: 136917.3
The remainder is 336 after subtracting 1734 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 10:
578 can be fit into 3360 5 times, resulting in a remainder of 470.
Write down 5 as next digit of the result. 
Result so far: 136917.35
Subtracting 2890 from 3360 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 11:
If we divide 4700 by 578, we get 8 and a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 136917.358
Deduct 4624 from 4700 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
578 can be fit into 760 1 times, resulting in a remainder of 182.
Put 1 as the next digit of the answer. 
Result so far: 136917.3581
The remainder is 182 after subtracting 578 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 13:
The number 578 fits into 1820 3 times, leaving a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 136917.35813
Subtracting 1734 from 1820 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 14:
860 divided by 578 is 1 with a remainder of 282.
Record the quotient 1 as the next digit in the result. 
Result so far: 136917.358131
Subtract 578 from 860 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 15:
578 goes into 2820 4 times with a remainder of 508.
The next digit of our result is 4. 
Result so far: 136917.3581314
Subtract 2312 from 2820 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 16:
When dividing 5080 by 578, we get 8 with a remainder of 456.
Write down 8 as next digit of the result. 
Result so far: 136917.35813148
Subtracting 4624 from 5080 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

In conclusion, the division gives 136917.35813148 with a balance of 4.56e-07.
