13570491 divided by 280 
The aim is to understand the frequency of 280 in 13570491.

Going ahead to step 1:
280 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 280

Step 2:
280 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 280

Going ahead to step 3:
135 divided by 280 is 0 with a remainder of 135.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 135 and we're left with 135.
Bring next digit (7) of the dividend behind the 135 and repeat the process: 1357 / 280

On to step 4:
280 can be fit into 1357 4 times, resulting in a remainder of 237.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1120 away from 1357, we end up with 237.
Append the next digit (0) from the dividend to 237 and continue with: 2370 / 280

Going ahead to step 5:
2370 divided by 280 is 8 with a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we subtract 2240 from 2370, we get 130.
Fetch the next digit (4) from the dividend, attach it to 130 and continue: 1304 / 280

Step 6:
1304 divided by 280 is 4 with a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 484.0
Subtracting 1120 from 1304 leaves us with 184.
Fetch the next digit (9) from the dividend, attach it to 184 and continue: 1849 / 280

Moving on to step 7:
If we divide 1849 by 280, we get 6 and a remainder of 169.
The number 6 becomes the next digit in our result. 
Result so far: 4846.0
Deduct 1680 from 1849 and we're left with 169.
Include the next digit (1) from the dividend after 169, then repeat: 1691 / 280

Step 8:
The number 280 fits into 1691 6 times, leaving a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 48466.0
If we take 1680 away from 1691, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
The number 280 fits into 110 0 times, leaving a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 48466.0
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
280 goes into 1100 3 times with a remainder of 260.
Write down 3 as next digit of the result. 
Result so far: 48466.03
Deduct 840 from 1100 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
280 goes into 2600 9 times with a remainder of 80.
Record the quotient 9 as the next digit in the result. 
Result so far: 48466.039
The remainder is 80 after subtracting 2520 from 2600.
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 12:
The number 280 fits into 800 2 times, leaving a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 48466.0392
Deduct 560 from 800 and we're left 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.

Advancing to step 13:
2400 divided by 280 is 8 with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 48466.03928
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.

Advancing to step 14:
1600 divided by 280 is 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 48466.039285
Subtract 1400 from 1600 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.

Step 15:
280 can be fit into 2000 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 48466.0392857
If we subtract 1960 from 2000, we get 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 16:
280 goes into 400 1 times with a remainder of 120.
The next digit of our result is 1. 
Result so far: 48466.03928571
Subtract 280 from 400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 48466.03928571 with a balance of 1.2e-07.
