We divide 15524429 by 280
The aim is to understand the frequency of 280 in 15524429.

Advancing to step 1:
When dividing 1 by 280, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 280

Let's proceed to step 2:
15 divided by 280 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 280

Going ahead to step 3:
When dividing 155 by 280, we get 0 with a remainder of 155.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 155, we get 155.
Append the next digit (2) from the dividend to 155 and continue with: 1552 / 280

Let's proceed to step 4:
1552 divided by 280 is 5 with a remainder of 152.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 1400 from 1552 leaves us with 152.
Bring next digit (4) of the dividend behind the 152 and repeat the process: 1524 / 280

Advancing to step 5:
If we divide 1524 by 280, we get 5 and a remainder of 124.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtract 1400 from 1524 to get 124.
Append the next digit (4) from the dividend to 124 and continue with: 1244 / 280

Advancing to step 6:
280 can be fit into 1244 4 times, resulting in a remainder of 124.
Write down 4 as next digit of the result. 
Result so far: 554.0
The remainder is 124 after subtracting 1120 from 1244.
Fetch the next digit (2) from the dividend, attach it to 124 and continue: 1242 / 280

Advancing to step 7:
If we divide 1242 by 280, we get 4 and a remainder of 122.
The next digit of our result is 4. 
Result so far: 5544.0
Subtracting 1120 from 1242 leaves us with 122.
Include the next digit (9) from the dividend after 122, then repeat: 1229 / 280

Advancing to step 8:
The number 280 fits into 1229 4 times, leaving a remainder of 109.
The number 4 becomes the next digit in our result. 
Result so far: 55444.0
Deduct 1120 from 1229 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 9:
When dividing 1090 by 280, we get 3 with a remainder of 250.
Record the quotient 3 as the next digit in the result. 
Result so far: 55444.3
The remainder is 250 after subtracting 840 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
2500 divided by 280 is 8 with a remainder of 260.
Write down 8 as next digit of the result. 
Result so far: 55444.38
The remainder is 260 after subtracting 2240 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
2600 divided by 280 is 9 with a remainder of 80.
Put 9 as the next digit of the answer. 
Result so far: 55444.389
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.

Going ahead to step 12:
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: 55444.3892
Subtract 560 from 800 to 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.

On to step 13:
280 goes into 2400 8 times with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 55444.38928
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 14:
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: 55444.389285
Deduct 1400 from 1600 and we're left 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.

Let's proceed to step 15:
When dividing 2000 by 280, we get 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 55444.3892857
Subtract 1960 from 2000 to 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.

Let's proceed to step 16:
When dividing 400 by 280, we get 1 with a remainder of 120.
The next digit of our result is 1. 
Result so far: 55444.38928571
If we take 280 away from 400, 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.

In conclusion, the division gives 55444.38928571 with a balance of 1.2e-07.
