We're dividing 3784265 by 280 
The aim is to understand the frequency of 280 in 3784265.

Advancing to step 1:
280 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 280

Let's proceed to step 2:
280 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 280

On to step 3:
280 goes into 378 1 times with a remainder of 98.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 280 away from 378, we end up with 98.
Take the next digit (4) from the dividend and append it to 98, then repeat: 984 / 280

Step 4:
984 divided by 280 is 3 with a remainder of 144.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 840 from 984 leaves us with 144.
Fetch the next digit (2) from the dividend, attach it to 144 and continue: 1442 / 280

Step 5:
The number 280 fits into 1442 5 times, leaving a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we take 1400 away from 1442, we end up with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 280

Step 6:
280 can be fit into 426 1 times, resulting in a remainder of 146.
The next digit of our result is 1. 
Result so far: 1351.0
If we subtract 280 from 426, we get 146.
Fetch the next digit (5) from the dividend, attach it to 146 and continue: 1465 / 280

On to step 7:
280 goes into 1465 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 13515.0
If we take 1400 away from 1465, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
When dividing 650 by 280, we get 2 with a remainder of 90.
The next digit of our result is 2. 
Result so far: 13515.2
Subtracting 560 from 650 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 9:
900 divided by 280 is 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 13515.23
If we subtract 840 from 900, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
The number 280 fits into 600 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 13515.232
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
The number 280 fits into 400 1 times, leaving a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 13515.2321
Deduct 280 from 400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
When dividing 1200 by 280, we get 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 13515.23214
If we take 1120 away from 1200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
When dividing 800 by 280, we get 2 with a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 13515.232142
Subtracting 560 from 800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
280 can be fit into 2400 8 times, resulting in a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 13515.2321428
The remainder is 160 after subtracting 2240 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
280 goes into 1600 5 times with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 13515.23214285
Subtracting 1400 from 1600 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 13515.23214285 and a remainder of 2e-07.
