23133175 divided by 280 
The aim is to understand the frequency of 280 in 23133175.

Going ahead to step 1:
When dividing 2 by 280, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 280

Step 2:
When dividing 23 by 280, we get 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 280

Going ahead to step 3:
The number 280 fits into 231 0 times, leaving a remainder of 231.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 231 after subtracting 0 from 231.
Take the next digit (3) from the dividend and append it to 231, then repeat: 2313 / 280

Going ahead to step 4:
If we divide 2313 by 280, we get 8 and a remainder of 73.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 2240 from 2313 and we're left with 73.
Bring next digit (3) of the dividend behind the 73 and repeat the process: 733 / 280

On to step 5:
280 goes into 733 2 times with a remainder of 173.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 560 from 733, we get 173.
Take the next digit (1) from the dividend and append it to 173, then repeat: 1731 / 280

On to step 6:
280 can be fit into 1731 6 times, resulting in a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 826.0
If we take 1680 away from 1731, we end up with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 280

Moving on to step 7:
If we divide 517 by 280, we get 1 and a remainder of 237.
Write down 1 as next digit of the result. 
Result so far: 8261.0
Subtract 280 from 517 to get 237.
Bring next digit (5) of the dividend behind the 237 and repeat the process: 2375 / 280

Going ahead to step 8:
When dividing 2375 by 280, we get 8 with a remainder of 135.
Record the quotient 8 as the next digit in the result. 
Result so far: 82618.0
If we take 2240 away from 2375, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 9:
When dividing 1350 by 280, we get 4 with a remainder of 230.
Record the quotient 4 as the next digit in the result. 
Result so far: 82618.4
If we subtract 1120 from 1350, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
2300 divided by 280 is 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 82618.48
Subtract 2240 from 2300 to 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 11:
280 goes into 600 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 82618.482
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.

Going ahead to step 12:
The number 280 fits into 400 1 times, leaving a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 82618.4821
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.

Moving on to step 13:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 82618.48214
If we subtract 1120 from 1200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
280 can be fit into 800 2 times, resulting in a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 82618.482142
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.

Step 15:
If we divide 2400 by 280, we get 8 and a remainder of 160.
The next digit of our result is 8. 
Result so far: 82618.4821428
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.

Going ahead to step 16:
The number 280 fits into 1600 5 times, leaving a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 82618.48214285
If we subtract 1400 from 1600, we 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.

The final result is 82618.48214285 with a remainder of 2e-07.
