We look at the division of 396007 by 90 
Our goal is to divide 396007 by 90.

On to step 1:
90 can be fit into 3 0 times, resulting in 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.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 90

On to step 2:
When dividing 39 by 90, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 90

Let's proceed to step 3:
If we divide 396 by 90, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 360 from 396 and we're left with 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 90

On to step 4:
The number 90 fits into 360 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 360 from 360, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 90

Let's proceed to step 5:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 440.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 90

On to step 6:
When dividing 7 by 90, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 4400.0
Subtract 0 from 7 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 7:
90 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 4400.0
If we subtract 0 from 70, we 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.

Advancing to step 8:
90 can be fit into 700 7 times, resulting in a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 4400.07
Subtract 630 from 700 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.

Moving on to step 9:
90 goes into 700 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 4400.077
If we subtract 630 from 700, we 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.

Our division results in 4400.077 with a remaining 0.007.
