We're dividing 448689 by 73 
We want to figure out the number of times 448689 can be divided by 73.

Advancing to step 1:
73 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 73

Advancing to step 2:
73 can be fit into 44 0 times, resulting in a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 73

On to step 3:
448 divided by 73 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 438 from 448 to get 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 73

Moving on to step 4:
When dividing 106 by 73, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 61.0
Deduct 73 from 106 and we're left with 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 73

Going ahead to step 5:
The number 73 fits into 338 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 614.0
If we take 292 away from 338, we end up with 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 73

On to step 6:
The number 73 fits into 469 6 times, leaving a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 6146.0
Subtracting 438 from 469 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
The number 73 fits into 310 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 6146.4
Subtract 292 from 310 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
73 can be fit into 180 2 times, resulting in a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 6146.42
If we take 146 away from 180, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
73 can be fit into 340 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 6146.424
If we subtract 292 from 340, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
When dividing 480 by 73, we get 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 6146.4246
Subtract 438 from 480 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
If we divide 420 by 73, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 6146.42465
Deduct 365 from 420 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
If we divide 550 by 73, we get 7 and a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 6146.424657
Subtracting 511 from 550 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
73 can be fit into 390 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 6146.4246575
The remainder is 25 after subtracting 365 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
If we divide 250 by 73, we get 3 and a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 6146.42465753
Subtract 219 from 250 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

In conclusion, the division gives 6146.42465753 with a balance of 3.1e-08.
