300906 ÷ 73 
We want to figure out the number of times 300906 can be divided by 73.

On to step 1:
If we divide 3 by 73, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 73

Step 2:
73 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 73

Step 3:
The number 73 fits into 300 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 292 from 300 and we're left with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 73

Moving on to step 4:
If we divide 89 by 73, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 73 from 89 and we're left with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 73

Going ahead to step 5:
73 can be fit into 160 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 412.0
The remainder is 14 after subtracting 146 from 160.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 73

Step 6:
When dividing 146 by 73, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 4122.0
Subtract 146 from 146 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 73 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4122.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 73, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4122.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4122.0, and the remainder is 0.0.
