We're dividing 25281829 by 79 
The aim is to understand the frequency of 79 in 25281829.

Let's proceed to step 1:
When dividing 2 by 79, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 79

On to step 2:
79 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 79

Moving on to step 3:
252 divided by 79 is 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 237 from 252 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 79

Advancing to step 4:
The number 79 fits into 158 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 158 from 158, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 79

Moving on to step 5:
If we divide 1 by 79, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 320.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 79

Step 6:
The number 79 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 3200.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 79

Going ahead to step 7:
182 divided by 79 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 32002.0
The remainder is 24 after subtracting 158 from 182.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 79

Step 8:
The number 79 fits into 249 3 times, leaving a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 320023.0
Subtracting 237 from 249 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 79 fits into 120 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 320023.1
If we take 79 away from 120, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
410 divided by 79 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 320023.15
Deduct 395 from 410 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
79 goes into 150 1 times with a remainder of 71.
The next digit of our result is 1. 
Result so far: 320023.151
The remainder is 71 after subtracting 79 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 12:
The number 79 fits into 710 8 times, leaving a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 320023.1518
Subtract 632 from 710 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 13:
79 goes into 780 9 times with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 320023.15189
If we subtract 711 from 780, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 14:
690 divided by 79 is 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 320023.151898
If we subtract 632 from 690, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 15:
When dividing 580 by 79, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 320023.1518987
If we subtract 553 from 580, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 16:
If we divide 270 by 79, we get 3 and a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 320023.15189873
If we subtract 237 from 270, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final result is 320023.15189873 with a remainder of 3.3e-08.
