We look at the division of 9090 by 73 
Let's see how many times 73 fits into 9090.

Going ahead to step 1:
When dividing 9 by 73, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 73

Step 2:
73 can be fit into 90 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 73 from 90, we get 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 73

Step 3:
73 can be fit into 179 2 times, resulting in a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 146 away from 179, we end up with 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 73

Step 4:
When dividing 330 by 73, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 124.0
Subtract 292 from 330 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 5:
380 divided by 73 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 124.5
Subtract 365 from 380 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 6:
When dividing 150 by 73, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 124.52
If we take 146 away from 150, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
If we divide 40 by 73, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 124.52
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 73 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 124.5205
If we take 365 away from 400, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
73 goes into 350 4 times with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 124.52054
Subtracting 292 from 350 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
73 goes into 580 7 times with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 124.520547
If we subtract 511 from 580, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 11:
When dividing 690 by 73, we get 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 124.5205479
If we subtract 657 from 690, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
When dividing 330 by 73, we get 4 with a remainder of 38.
The next digit of our result is 4. 
Result so far: 124.52054794
Subtracting 292 from 330 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 124.52054794 and a remainder of 3.8e-08.
