We look at the division of 716421 by 73 
We want to figure out the number of times 716421 can be divided by 73.

Let's proceed to step 1:
73 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 73

Going ahead to step 2:
71 divided by 73 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 73

Going ahead to step 3:
If we divide 716 by 73, we get 9 and a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 59 after subtracting 657 from 716.
Fetch the next digit (4) from the dividend, attach it to 59 and continue: 594 / 73

Advancing to step 4:
If we divide 594 by 73, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtracting 584 from 594 leaves us with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 73

Step 5:
If we divide 102 by 73, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 981.0
If we take 73 away from 102, we end up with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 73

Going ahead to step 6:
When dividing 291 by 73, we get 3 with a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 9813.0
If we subtract 219 from 291, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 7:
When dividing 720 by 73, we get 9 with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 9813.9
If we take 657 away from 720, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 8:
630 divided by 73 is 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 9813.98
If we take 584 away from 630, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
73 can be fit into 460 6 times, resulting in a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 9813.986
Subtracting 438 from 460 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
73 goes into 220 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 9813.9863
If we subtract 219 from 220, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
73 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 9813.9863
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
73 goes into 100 1 times with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 9813.986301
If we take 73 away from 100, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
When dividing 270 by 73, we get 3 with a remainder of 51.
The next digit of our result is 3. 
Result so far: 9813.9863013
If we subtract 219 from 270, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 14:
73 goes into 510 6 times with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 9813.98630136
Deduct 438 from 510 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 9813.98630136 with a remainder of 7.2e-08.
