We look at the division of 406434 by 73 
We want to figure out the number of times 406434 can be divided by 73.

On to step 1:
4 divided by 73 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 73

Let's proceed to step 2:
40 divided by 73 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 73

Step 3:
If we divide 406 by 73, we get 5 and a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 365 from 406, we get 41.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 73

On to step 4:
73 can be fit into 414 5 times, resulting in a remainder of 49.
The next digit of our result is 5. 
Result so far: 55.0
If we take 365 away from 414, we end up with 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 73

Step 5:
If we divide 493 by 73, we get 6 and a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 556.0
The remainder is 55 after subtracting 438 from 493.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 73

Step 6:
73 goes into 554 7 times with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 5567.0
If we take 511 away from 554, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
73 goes into 430 5 times with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 5567.5
The remainder is 65 after subtracting 365 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
If we divide 650 by 73, we get 8 and a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 5567.58
Deduct 584 from 650 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
73 goes into 660 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 5567.589
Deduct 657 from 660 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
If we divide 30 by 73, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 5567.589
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
73 can be fit into 300 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 5567.58904
Subtracting 292 from 300 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
If we divide 80 by 73, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 5567.589041
Subtract 73 from 80 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
70 divided by 73 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 5567.589041
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
73 can be fit into 700 9 times, resulting in a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 5567.58904109
The remainder is 43 after subtracting 657 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 5567.58904109 and a remainder of 4.3e-08.
