We look at the division of 79201246 by 578 
The aim is to understand the frequency of 578 in 79201246.

Advancing to step 1:
578 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
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 578

Let's proceed to step 2:
79 divided by 578 is 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Grab the next digit (2) from the dividend, add it to 79, then carry on: 792 / 578

On to step 3:
578 goes into 792 1 times with a remainder of 214.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 578 from 792 and we're left with 214.
Include the next digit (0) from the dividend after 214, then repeat: 2140 / 578

Advancing to step 4:
578 can be fit into 2140 3 times, resulting in a remainder of 406.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1734 away from 2140, we end up with 406.
Include the next digit (1) from the dividend after 406, then repeat: 4061 / 578

On to step 5:
The number 578 fits into 4061 7 times, leaving a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtracting 4046 from 4061 leaves us with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 578

On to step 6:
578 goes into 152 0 times with a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 1370.0
If we take 0 away from 152, we end up with 152.
Bring next digit (4) of the dividend behind the 152 and repeat the process: 1524 / 578

Advancing to step 7:
If we divide 1524 by 578, we get 2 and a remainder of 368.
Put 2 as the next digit of the answer. 
Result so far: 13702.0
If we take 1156 away from 1524, we end up with 368.
Bring next digit (6) of the dividend behind the 368 and repeat the process: 3686 / 578

Moving on to step 8:
When dividing 3686 by 578, we get 6 with a remainder of 218.
Record the quotient 6 as the next digit in the result. 
Result so far: 137026.0
Subtracting 3468 from 3686 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 9:
578 goes into 2180 3 times with a remainder of 446.
The number 3 becomes the next digit in our result. 
Result so far: 137026.3
Subtract 1734 from 2180 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 10:
If we divide 4460 by 578, we get 7 and a remainder of 414.
The number 7 becomes the next digit in our result. 
Result so far: 137026.37
If we take 4046 away from 4460, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 11:
If we divide 4140 by 578, we get 7 and a remainder of 94.
The number 7 becomes the next digit in our result. 
Result so far: 137026.377
The remainder is 94 after subtracting 4046 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final result is 137026.377 with a remainder of 0.0094.
