We're dividing 63023923 by 449 
The aim is to understand the frequency of 449 in 63023923.

Step 1:
If we divide 6 by 449, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 449

Let's proceed to step 2:
449 goes into 63 0 times with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 449

On to step 3:
If we divide 630 by 449, we get 1 and a remainder of 181.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 449 from 630 leaves us with 181.
Fetch the next digit (2) from the dividend, attach it to 181 and continue: 1812 / 449

Going ahead to step 4:
The number 449 fits into 1812 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 1796 from 1812, we get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 449

Moving on to step 5:
163 divided by 449 is 0 with a remainder of 163.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Subtracting 0 from 163 leaves us with 163.
Bring next digit (9) of the dividend behind the 163 and repeat the process: 1639 / 449

Step 6:
449 goes into 1639 3 times with a remainder of 292.
The next digit of our result is 3. 
Result so far: 1403.0
Deduct 1347 from 1639 and we're left with 292.
Grab the next digit (2) from the dividend, add it to 292, then carry on: 2922 / 449

Going ahead to step 7:
449 goes into 2922 6 times with a remainder of 228.
The next digit of our result is 6. 
Result so far: 14036.0
If we take 2694 away from 2922, we end up with 228.
Fetch the next digit (3) from the dividend, attach it to 228 and continue: 2283 / 449

Going ahead to step 8:
When dividing 2283 by 449, we get 5 with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 140365.0
The remainder is 38 after subtracting 2245 from 2283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
449 can be fit into 380 0 times, resulting in a remainder of 380.
The next digit of our result is 0. 
Result so far: 140365.0
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 10:
449 goes into 3800 8 times with a remainder of 208.
The next digit of our result is 8. 
Result so far: 140365.08
Subtract 3592 from 3800 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 11:
449 goes into 2080 4 times with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 140365.084
Deduct 1796 from 2080 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 12:
449 goes into 2840 6 times with a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 140365.0846
Deduct 2694 from 2840 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 13:
1460 divided by 449 is 3 with a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 140365.08463
Subtracting 1347 from 1460 leaves us 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 14:
1130 divided by 449 is 2 with a remainder of 232.
Record the quotient 2 as the next digit in the result. 
Result so far: 140365.084632
Subtracting 898 from 1130 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 15:
2320 divided by 449 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 140365.0846325
Deduct 2245 from 2320 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 16:
750 divided by 449 is 1 with a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 140365.08463251
Deduct 449 from 750 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

The quotient of the division is 140365.08463251, and the remainder is 3.01e-07.
