We're dividing 71027842 by 280 
The aim is to understand the frequency of 280 in 71027842.

Let's proceed to step 1:
7 divided by 280 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 280

Moving on to step 2:
71 divided by 280 is 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 280

Let's proceed to step 3:
When dividing 710 by 280, we get 2 with a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 150 after subtracting 560 from 710.
Fetch the next digit (2) from the dividend, attach it to 150 and continue: 1502 / 280

Moving on to step 4:
1502 divided by 280 is 5 with a remainder of 102.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 1400 from 1502 and we're left with 102.
Include the next digit (7) from the dividend after 102, then repeat: 1027 / 280

Advancing to step 5:
280 can be fit into 1027 3 times, resulting in a remainder of 187.
Use 3 as the next digit of our solution. 
Result so far: 253.0
Deduct 840 from 1027 and we're left with 187.
Fetch the next digit (8) from the dividend, attach it to 187 and continue: 1878 / 280

Step 6:
280 can be fit into 1878 6 times, resulting in a remainder of 198.
Use 6 as the next digit of our solution. 
Result so far: 2536.0
Subtract 1680 from 1878 to get 198.
Take the next digit (4) from the dividend and append it to 198, then repeat: 1984 / 280

Let's proceed to step 7:
1984 divided by 280 is 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 25367.0
If we take 1960 away from 1984, we end up with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 280

Step 8:
280 goes into 242 0 times with a remainder of 242.
Put 0 as the next digit of the answer. 
Result so far: 253670.0
If we take 0 away from 242, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 9:
2420 divided by 280 is 8 with a remainder of 180.
Put 8 as the next digit of the answer. 
Result so far: 253670.8
The remainder is 180 after subtracting 2240 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 280, we get 6 with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 253670.86
If we take 1680 away from 1800, we end up 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.

Moving on to step 11:
1200 divided by 280 is 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 253670.864
Subtracting 1120 from 1200 leaves us 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 12:
When dividing 800 by 280, we get 2 with a remainder of 240.
The next digit of our result is 2. 
Result so far: 253670.8642
If we subtract 560 from 800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
280 can be fit into 2400 8 times, resulting in a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 253670.86428
Subtracting 2240 from 2400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
If we divide 1600 by 280, we get 5 and a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 253670.864285
If we take 1400 away from 1600, we end up 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.

On to step 15:
280 can be fit into 2000 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 253670.8642857
The remainder is 40 after subtracting 1960 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
280 can be fit into 400 1 times, resulting in a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 253670.86428571
The remainder is 120 after subtracting 280 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 253670.86428571 and a remainder of 1.2e-07.
