We're dividing 2257520 by 447 
The aim is to understand the frequency of 447 in 2257520.

Going ahead to step 1:
2 divided by 447 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 447

Let's proceed to step 2:
22 divided by 447 is 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 447

Moving on to step 3:
447 goes into 225 0 times with a remainder of 225.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 225 to get 225.
Append the next digit (7) from the dividend to 225 and continue with: 2257 / 447

Let's proceed to step 4:
If we divide 2257 by 447, we get 5 and a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 2235 from 2257, we get 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 447

Advancing to step 5:
447 goes into 225 0 times with a remainder of 225.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtract 0 from 225 to get 225.
Append the next digit (2) from the dividend to 225 and continue with: 2252 / 447

Step 6:
If we divide 2252 by 447, we get 5 and a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 505.0
Deduct 2235 from 2252 and we're left with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 447

Moving on to step 7:
When dividing 170 by 447, we get 0 with a remainder of 170.
The next digit of our result is 0. 
Result so far: 5050.0
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 8:
If we divide 1700 by 447, we get 3 and a remainder of 359.
The next digit of our result is 3. 
Result so far: 5050.3
Subtracting 1341 from 1700 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 9:
If we divide 3590 by 447, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 5050.38
If we take 3576 away from 3590, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
The number 447 fits into 140 0 times, leaving a remainder of 140.
The next digit of our result is 0. 
Result so far: 5050.38
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
447 can be fit into 1400 3 times, resulting in a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 5050.3803
Subtract 1341 from 1400 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 12:
447 goes into 590 1 times with a remainder of 143.
The next digit of our result is 1. 
Result so far: 5050.38031
The remainder is 143 after subtracting 447 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 13:
447 goes into 1430 3 times with a remainder of 89.
Write down 3 as next digit of the result. 
Result so far: 5050.380313
Subtract 1341 from 1430 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 14:
If we divide 890 by 447, we get 1 and a remainder of 443.
Use 1 as the next digit of our solution. 
Result so far: 5050.3803131
Subtracting 447 from 890 leaves us with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Going ahead to step 15:
4430 divided by 447 is 9 with a remainder of 407.
Record the quotient 9 as the next digit in the result. 
Result so far: 5050.38031319
If we take 4023 away from 4430, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

The final result is 5050.38031319 with a remainder of 4.07e-07.
