4744737 ÷ 280 
The aim is to understand the frequency of 280 in 4744737.

Step 1:
The number 280 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 280

Step 2:
47 divided by 280 is 0 with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Fetch the next digit (4) from the dividend, attach it to 47 and continue: 474 / 280

Step 3:
The number 280 fits into 474 1 times, leaving a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 280 from 474 leaves us with 194.
Include the next digit (4) from the dividend after 194, then repeat: 1944 / 280

On to step 4:
When dividing 1944 by 280, we get 6 with a remainder of 264.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 264 after subtracting 1680 from 1944.
Include the next digit (7) from the dividend after 264, then repeat: 2647 / 280

Step 5:
2647 divided by 280 is 9 with a remainder of 127.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
Deduct 2520 from 2647 and we're left with 127.
Fetch the next digit (3) from the dividend, attach it to 127 and continue: 1273 / 280

Let's proceed to step 6:
If we divide 1273 by 280, we get 4 and a remainder of 153.
The next digit of our result is 4. 
Result so far: 1694.0
If we subtract 1120 from 1273, we get 153.
Fetch the next digit (7) from the dividend, attach it to 153 and continue: 1537 / 280

Let's proceed to step 7:
1537 divided by 280 is 5 with a remainder of 137.
The number 5 becomes the next digit in our result. 
Result so far: 16945.0
Subtract 1400 from 1537 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 8:
280 goes into 1370 4 times with a remainder of 250.
Write down 4 as next digit of the result. 
Result so far: 16945.4
If we take 1120 away from 1370, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 9:
280 goes into 2500 8 times with a remainder of 260.
The number 8 becomes the next digit in our result. 
Result so far: 16945.48
Deduct 2240 from 2500 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.

Moving on to step 10:
When dividing 2600 by 280, we get 9 with a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 16945.489
Subtract 2520 from 2600 to 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.

Let's proceed to step 11:
280 goes into 800 2 times with a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 16945.4892
The remainder is 240 after subtracting 560 from 800.
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 12:
2400 divided by 280 is 8 with a remainder of 160.
The next digit of our result is 8. 
Result so far: 16945.48928
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.

On to step 13:
If we divide 1600 by 280, we get 5 and a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 16945.489285
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 14:
The number 280 fits into 2000 7 times, leaving a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 16945.4892857
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.

Step 15:
When dividing 400 by 280, we get 1 with a remainder of 120.
Record the quotient 1 as the next digit in the result. 
Result so far: 16945.48928571
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.

Our division results in 16945.48928571 with a remaining 1.2e-07.
