45223192 ÷ 578 
The aim is to understand the frequency of 578 in 45223192.

Let's proceed to step 1:
When dividing 4 by 578, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 578

Let's proceed to step 2:
45 divided by 578 is 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 578

Let's proceed to step 3:
If we divide 452 by 578, we get 0 and a remainder of 452.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 452, we end up with 452.
Bring next digit (2) of the dividend behind the 452 and repeat the process: 4522 / 578

On to step 4:
578 can be fit into 4522 7 times, resulting in a remainder of 476.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4046 from 4522, we get 476.
Bring next digit (3) of the dividend behind the 476 and repeat the process: 4763 / 578

Let's proceed to step 5:
4763 divided by 578 is 8 with a remainder of 139.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtracting 4624 from 4763 leaves us with 139.
Include the next digit (1) from the dividend after 139, then repeat: 1391 / 578

Moving on to step 6:
If we divide 1391 by 578, we get 2 and a remainder of 235.
Use 2 as the next digit of our solution. 
Result so far: 782.0
If we take 1156 away from 1391, we end up with 235.
Bring next digit (9) of the dividend behind the 235 and repeat the process: 2359 / 578

Going ahead to step 7:
The number 578 fits into 2359 4 times, leaving a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 7824.0
If we subtract 2312 from 2359, we get 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 578

Advancing to step 8:
578 can be fit into 472 0 times, resulting in a remainder of 472.
Write down 0 as next digit of the result. 
Result so far: 78240.0
The remainder is 472 after subtracting 0 from 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 9:
When dividing 4720 by 578, we get 8 with a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 78240.8
If we take 4624 away from 4720, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 10:
960 divided by 578 is 1 with a remainder of 382.
Record the quotient 1 as the next digit in the result. 
Result so far: 78240.81
Deduct 578 from 960 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 11:
578 goes into 3820 6 times with a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 78240.816
Subtracting 3468 from 3820 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 12:
The number 578 fits into 3520 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 78240.8166
The remainder is 52 after subtracting 3468 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 78240.8166 and a remainder of 0.00052.
