45879320 ÷ 579 
The aim is to understand the frequency of 579 in 45879320.

Moving on to step 1:
4 divided by 579 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 579

Moving on to step 2:
579 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 579

Let's proceed to step 3:
579 goes into 458 0 times with a remainder of 458.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 458 and we're left with 458.
Include the next digit (7) from the dividend after 458, then repeat: 4587 / 579

Advancing to step 4:
If we divide 4587 by 579, we get 7 and a remainder of 534.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 4053 from 4587 to get 534.
Grab the next digit (9) from the dividend, add it to 534, then carry on: 5349 / 579

Step 5:
If we divide 5349 by 579, we get 9 and a remainder of 138.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
The remainder is 138 after subtracting 5211 from 5349.
Include the next digit (3) from the dividend after 138, then repeat: 1383 / 579

Advancing to step 6:
The number 579 fits into 1383 2 times, leaving a remainder of 225.
The number 2 becomes the next digit in our result. 
Result so far: 792.0
Subtract 1158 from 1383 to get 225.
Fetch the next digit (2) from the dividend, attach it to 225 and continue: 2252 / 579

Let's proceed to step 7:
579 goes into 2252 3 times with a remainder of 515.
The number 3 becomes the next digit in our result. 
Result so far: 7923.0
If we take 1737 away from 2252, we end up with 515.
Bring next digit (0) of the dividend behind the 515 and repeat the process: 5150 / 579

Moving on to step 8:
If we divide 5150 by 579, we get 8 and a remainder of 518.
The next digit of our result is 8. 
Result so far: 79238.0
Subtracting 4632 from 5150 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Let's proceed to step 9:
If we divide 5180 by 579, we get 8 and a remainder of 548.
The next digit of our result is 8. 
Result so far: 79238.8
Subtract 4632 from 5180 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 10:
579 can be fit into 5480 9 times, resulting in a remainder of 269.
Use 9 as the next digit of our solution. 
Result so far: 79238.89
Subtract 5211 from 5480 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 11:
If we divide 2690 by 579, we get 4 and a remainder of 374.
Use 4 as the next digit of our solution. 
Result so far: 79238.894
Subtracting 2316 from 2690 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 12:
The number 579 fits into 3740 6 times, leaving a remainder of 266.
Use 6 as the next digit of our solution. 
Result so far: 79238.8946
Deduct 3474 from 3740 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 13:
When dividing 2660 by 579, we get 4 with a remainder of 344.
The next digit of our result is 4. 
Result so far: 79238.89464
If we take 2316 away from 2660, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 14:
3440 divided by 579 is 5 with a remainder of 545.
The number 5 becomes the next digit in our result. 
Result so far: 79238.894645
Subtract 2895 from 3440 to get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Let's proceed to step 15:
579 goes into 5450 9 times with a remainder of 239.
Put 9 as the next digit of the answer. 
Result so far: 79238.8946459
If we subtract 5211 from 5450, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 16:
2390 divided by 579 is 4 with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 79238.89464594
The remainder is 74 after subtracting 2316 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 79238.89464594 with a remaining 7.4e-08.
