We divide 73209703 by 449
The aim is to understand the frequency of 449 in 73209703.

Step 1:
449 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 449

Going ahead to step 2:
73 divided by 449 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Append the next digit (2) from the dividend to 73 and continue with: 732 / 449

Going ahead to step 3:
449 goes into 732 1 times with a remainder of 283.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 449 from 732 to get 283.
Bring next digit (0) of the dividend behind the 283 and repeat the process: 2830 / 449

On to step 4:
If we divide 2830 by 449, we get 6 and a remainder of 136.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 2694 away from 2830, we end up with 136.
Append the next digit (9) from the dividend to 136 and continue with: 1369 / 449

Moving on to step 5:
449 can be fit into 1369 3 times, resulting in a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 163.0
If we subtract 1347 from 1369, we get 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 449

Advancing to step 6:
If we divide 227 by 449, we get 0 and a remainder of 227.
Put 0 as the next digit of the answer. 
Result so far: 1630.0
If we subtract 0 from 227, we get 227.
Grab the next digit (0) from the dividend, add it to 227, then carry on: 2270 / 449

Going ahead to step 7:
449 goes into 2270 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 16305.0
If we take 2245 away from 2270, we end up with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 449

Moving on to step 8:
253 divided by 449 is 0 with a remainder of 253.
Put 0 as the next digit of the answer. 
Result so far: 163050.0
If we take 0 away from 253, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 9:
The number 449 fits into 2530 5 times, leaving a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 163050.5
Deduct 2245 from 2530 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 10:
449 can be fit into 2850 6 times, resulting in a remainder of 156.
The number 6 becomes the next digit in our result. 
Result so far: 163050.56
If we take 2694 away from 2850, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 11:
If we divide 1560 by 449, we get 3 and a remainder of 213.
The number 3 becomes the next digit in our result. 
Result so far: 163050.563
Subtracting 1347 from 1560 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 12:
449 can be fit into 2130 4 times, resulting in a remainder of 334.
The number 4 becomes the next digit in our result. 
Result so far: 163050.5634
Subtract 1796 from 2130 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 13:
If we divide 3340 by 449, we get 7 and a remainder of 197.
The number 7 becomes the next digit in our result. 
Result so far: 163050.56347
Subtracting 3143 from 3340 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 14:
When dividing 1970 by 449, we get 4 with a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 163050.563474
If we subtract 1796 from 1970, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 15:
If we divide 1740 by 449, we get 3 and a remainder of 393.
Record the quotient 3 as the next digit in the result. 
Result so far: 163050.5634743
The remainder is 393 after subtracting 1347 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Step 16:
449 goes into 3930 8 times with a remainder of 338.
The next digit of our result is 8. 
Result so far: 163050.56347438
If we subtract 3592 from 3930, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

In conclusion, the division gives 163050.56347438 with a balance of 3.38e-07.
