We're dividing 306473 by 90 
We want to figure out the number of times 306473 can be divided by 90.

Going ahead to step 1:
The number 90 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 90

Step 2:
30 divided by 90 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 90

Moving on to step 3:
306 divided by 90 is 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 3.0
If we take 270 away from 306, we end up with 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 90

Advancing to step 4:
If we divide 364 by 90, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Deduct 360 from 364 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 90

Advancing to step 5:
When dividing 47 by 90, we get 0 with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 340.0
Subtracting 0 from 47 leaves us with 47.
Append the next digit (3) from the dividend to 47 and continue with: 473 / 90

Advancing to step 6:
When dividing 473 by 90, we get 5 with a remainder of 23.
The next digit of our result is 5. 
Result so far: 3405.0
If we take 450 away from 473, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
If we divide 230 by 90, we get 2 and a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 3405.2
If we take 180 away from 230, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 3405.25
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
90 can be fit into 500 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 3405.255
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 3405.255 with a remaining 0.005.
