Let's divide 73123688 by 449
Our goal is to divide 73123688 by 449.

On to step 1:
When dividing 7 by 449, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 449

Let's proceed to step 2:
The number 449 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 449

Advancing to step 3:
The number 449 fits into 731 1 times, leaving a remainder of 282.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 449 from 731, we get 282.
Include the next digit (2) from the dividend after 282, then repeat: 2822 / 449

Step 4:
If we divide 2822 by 449, we get 6 and a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 2694 from 2822 to get 128.
Include the next digit (3) from the dividend after 128, then repeat: 1283 / 449

Going ahead to step 5:
449 goes into 1283 2 times with a remainder of 385.
Write down 2 as next digit of the result. 
Result so far: 162.0
Subtract 898 from 1283 to get 385.
Append the next digit (6) from the dividend to 385 and continue with: 3856 / 449

Advancing to step 6:
When dividing 3856 by 449, we get 8 with a remainder of 264.
Use 8 as the next digit of our solution. 
Result so far: 1628.0
If we take 3592 away from 3856, we end up with 264.
Include the next digit (8) from the dividend after 264, then repeat: 2648 / 449

Advancing to step 7:
The number 449 fits into 2648 5 times, leaving a remainder of 403.
Put 5 as the next digit of the answer. 
Result so far: 16285.0
Subtracting 2245 from 2648 leaves us with 403.
Append the next digit (8) from the dividend to 403 and continue with: 4038 / 449

On to step 8:
449 can be fit into 4038 8 times, resulting in a remainder of 446.
Use 8 as the next digit of our solution. 
Result so far: 162858.0
Subtract 3592 from 4038 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Going ahead to step 9:
449 can be fit into 4460 9 times, resulting in a remainder of 419.
Put 9 as the next digit of the answer. 
Result so far: 162858.9
Subtracting 4041 from 4460 leaves us with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Moving on to step 10:
When dividing 4190 by 449, we get 9 with a remainder of 149.
The next digit of our result is 9. 
Result so far: 162858.99
Deduct 4041 from 4190 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

In conclusion, the division gives 162858.99 with a balance of 0.149.
