We look at the division of 721448 by 73 
We want to figure out the number of times 721448 can be divided by 73.

Going ahead to step 1:
If we divide 7 by 73, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 73

Moving on to step 2:
If we divide 72 by 73, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 73

Moving on to step 3:
73 can be fit into 721 9 times, resulting in a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 657 from 721 and we're left with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 73

On to step 4:
When dividing 644 by 73, we get 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtracting 584 from 644 leaves us with 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 73

Advancing to step 5:
If we divide 604 by 73, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 988.0
Subtract 584 from 604 to get 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 73

Moving on to step 6:
73 can be fit into 208 2 times, resulting in a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 9882.0
If we subtract 146 from 208, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 7:
When dividing 620 by 73, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 9882.8
If we subtract 584 from 620, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
The number 73 fits into 360 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 9882.84
If we subtract 292 from 360, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
73 goes into 680 9 times with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 9882.849
If we take 657 away from 680, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
73 goes into 230 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 9882.8493
Subtracting 219 from 230 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
73 can be fit into 110 1 times, resulting in a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 9882.84931
Deduct 73 from 110 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
If we divide 370 by 73, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9882.849315
If we subtract 365 from 370, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
The number 73 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 9882.849315
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
73 goes into 500 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 9882.84931506
Subtract 438 from 500 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 9882.84931506 with a remaining 6.2e-08.
