Let's divide 550434 by 73
We're looking to find how many times 73 goes into 550434.

Step 1:
The number 73 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 73

Moving on to step 2:
If we divide 55 by 73, we get 0 and a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 73

On to step 3:
73 can be fit into 550 7 times, resulting in a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 511 from 550 to get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 73

Moving on to step 4:
73 goes into 394 5 times with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtract 365 from 394 to get 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 73

Moving on to step 5:
If we divide 293 by 73, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 754.0
The remainder is 1 after subtracting 292 from 293.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 73

On to step 6:
14 divided by 73 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 7540.0
The remainder is 14 after subtracting 0 from 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
73 can be fit into 140 1 times, resulting in a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 7540.1
If we take 73 away from 140, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 8:
670 divided by 73 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 7540.19
If we subtract 657 from 670, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
The number 73 fits into 130 1 times, leaving a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 7540.191
If we subtract 73 from 130, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
73 can be fit into 570 7 times, resulting in a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 7540.1917
Subtract 511 from 570 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 11:
When dividing 590 by 73, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 7540.19178
Subtracting 584 from 590 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
If we divide 60 by 73, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 7540.19178
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
The number 73 fits into 600 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7540.1917808
Deduct 584 from 600 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
The number 73 fits into 160 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 7540.19178082
If we subtract 146 from 160, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 7540.19178082 and a remainder of 1.4e-08.
