We're dividing 74280306 by 425 
The aim is to understand the frequency of 425 in 74280306.

Let's proceed to step 1:
425 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
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 425

Going ahead to step 2:
If we divide 74 by 425, we get 0 and a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 425

Step 3:
425 can be fit into 742 1 times, resulting in a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 425 from 742 and we're left with 317.
Fetch the next digit (8) from the dividend, attach it to 317 and continue: 3178 / 425

Moving on to step 4:
When dividing 3178 by 425, we get 7 with a remainder of 203.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 2975 away from 3178, we end up with 203.
Take the next digit (0) from the dividend and append it to 203, then repeat: 2030 / 425

Let's proceed to step 5:
2030 divided by 425 is 4 with a remainder of 330.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
If we take 1700 away from 2030, we end up with 330.
Take the next digit (3) from the dividend and append it to 330, then repeat: 3303 / 425

Let's proceed to step 6:
If we divide 3303 by 425, we get 7 and a remainder of 328.
The next digit of our result is 7. 
Result so far: 1747.0
Subtracting 2975 from 3303 leaves us with 328.
Fetch the next digit (0) from the dividend, attach it to 328 and continue: 3280 / 425

Advancing to step 7:
3280 divided by 425 is 7 with a remainder of 305.
Write down 7 as next digit of the result. 
Result so far: 17477.0
Deduct 2975 from 3280 and we're left with 305.
Fetch the next digit (6) from the dividend, attach it to 305 and continue: 3056 / 425

On to step 8:
If we divide 3056 by 425, we get 7 and a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 174777.0
If we take 2975 away from 3056, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
If we divide 810 by 425, we get 1 and a remainder of 385.
Record the quotient 1 as the next digit in the result. 
Result so far: 174777.1
Deduct 425 from 810 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 10:
If we divide 3850 by 425, we get 9 and a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 174777.19
The remainder is 25 after subtracting 3825 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
When dividing 250 by 425, we get 0 with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 174777.19
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
The number 425 fits into 2500 5 times, leaving a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 174777.1905
Subtract 2125 from 2500 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 13:
If we divide 3750 by 425, we get 8 and a remainder of 350.
Put 8 as the next digit of the answer. 
Result so far: 174777.19058
Deduct 3400 from 3750 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 14:
3500 divided by 425 is 8 with a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 174777.190588
The remainder is 100 after subtracting 3400 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 174777.190588 and a remainder of 1e-05.
