5628857 ÷ 447 
The aim is to understand the frequency of 447 in 5628857.

Step 1:
When dividing 5 by 447, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 447

Advancing to step 2:
447 can be fit into 56 0 times, resulting in a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Grab the next digit (2) from the dividend, add it to 56, then carry on: 562 / 447

Let's proceed to step 3:
If we divide 562 by 447, we get 1 and a remainder of 115.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 447 from 562 leaves us with 115.
Grab the next digit (8) from the dividend, add it to 115, then carry on: 1158 / 447

Advancing to step 4:
When dividing 1158 by 447, we get 2 with a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 894 from 1158 and we're left with 264.
Bring next digit (8) of the dividend behind the 264 and repeat the process: 2648 / 447

Going ahead to step 5:
2648 divided by 447 is 5 with a remainder of 413.
Use 5 as the next digit of our solution. 
Result so far: 125.0
The remainder is 413 after subtracting 2235 from 2648.
Bring next digit (5) of the dividend behind the 413 and repeat the process: 4135 / 447

On to step 6:
If we divide 4135 by 447, we get 9 and a remainder of 112.
The number 9 becomes the next digit in our result. 
Result so far: 1259.0
If we take 4023 away from 4135, we end up with 112.
Fetch the next digit (7) from the dividend, attach it to 112 and continue: 1127 / 447

Advancing to step 7:
If we divide 1127 by 447, we get 2 and a remainder of 233.
Use 2 as the next digit of our solution. 
Result so far: 12592.0
If we subtract 894 from 1127, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 8:
2330 divided by 447 is 5 with a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 12592.5
If we take 2235 away from 2330, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 9:
950 divided by 447 is 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 12592.52
The remainder is 56 after subtracting 894 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
The number 447 fits into 560 1 times, leaving a remainder of 113.
Put 1 as the next digit of the answer. 
Result so far: 12592.521
Deduct 447 from 560 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 11:
1130 divided by 447 is 2 with a remainder of 236.
Record the quotient 2 as the next digit in the result. 
Result so far: 12592.5212
Deduct 894 from 1130 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 12:
If we divide 2360 by 447, we get 5 and a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 12592.52125
If we take 2235 away from 2360, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 13:
When dividing 1250 by 447, we get 2 with a remainder of 356.
Write down 2 as next digit of the result. 
Result so far: 12592.521252
The remainder is 356 after subtracting 894 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 14:
The number 447 fits into 3560 7 times, leaving a remainder of 431.
The next digit of our result is 7. 
Result so far: 12592.5212527
The remainder is 431 after subtracting 3129 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Going ahead to step 15:
The number 447 fits into 4310 9 times, leaving a remainder of 287.
Use 9 as the next digit of our solution. 
Result so far: 12592.52125279
If we take 4023 away from 4310, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

The final result is 12592.52125279 with a remainder of 2.87e-07.
