We're dividing 6742641 by 280 
The aim is to understand the frequency of 280 in 6742641.

Advancing to step 1:
When dividing 6 by 280, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 280

Step 2:
When dividing 67 by 280, we get 0 with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 280

Going ahead to step 3:
If we divide 674 by 280, we get 2 and a remainder of 114.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 560 away from 674, we end up with 114.
Fetch the next digit (2) from the dividend, attach it to 114 and continue: 1142 / 280

On to step 4:
1142 divided by 280 is 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 1120 from 1142 to get 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 280

Let's proceed to step 5:
If we divide 226 by 280, we get 0 and a remainder of 226.
Put 0 as the next digit of the answer. 
Result so far: 240.0
Subtracting 0 from 226 leaves us with 226.
Include the next digit (4) from the dividend after 226, then repeat: 2264 / 280

Step 6:
2264 divided by 280 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 2408.0
The remainder is 24 after subtracting 2240 from 2264.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 280

Going ahead to step 7:
When dividing 241 by 280, we get 0 with a remainder of 241.
Put 0 as the next digit of the answer. 
Result so far: 24080.0
The remainder is 241 after subtracting 0 from 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 8:
The number 280 fits into 2410 8 times, leaving a remainder of 170.
Put 8 as the next digit of the answer. 
Result so far: 24080.8
Subtract 2240 from 2410 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 9:
When dividing 1700 by 280, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 24080.86
Deduct 1680 from 1700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
If we divide 200 by 280, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 24080.86
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
When dividing 2000 by 280, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 24080.8607
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 12:
When dividing 400 by 280, we get 1 with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 24080.86071
Subtracting 280 from 400 leaves us 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.

Advancing to step 13:
If we divide 1200 by 280, we get 4 and a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 24080.860714
The remainder is 80 after subtracting 1120 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
280 goes into 800 2 times with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 24080.8607142
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.

Let's proceed to step 15:
When dividing 2400 by 280, we get 8 with a remainder of 160.
The next digit of our result is 8. 
Result so far: 24080.86071428
If we subtract 2240 from 2400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 24080.86071428, and the remainder is 1.6e-07.
