447376 ÷ 90 
Let's see how many times 90 fits into 447376.

Moving on to step 1:
90 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 90

Let's proceed to step 2:
90 goes into 44 0 times with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 90

Step 3:
When dividing 447 by 90, we get 4 with a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 360 from 447 leaves us with 87.
Grab the next digit (3) from the dividend, add it to 87, then carry on: 873 / 90

On to step 4:
873 divided by 90 is 9 with a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we subtract 810 from 873, we get 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 90

Advancing to step 5:
The number 90 fits into 637 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 497.0
Deduct 630 from 637 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 90

Let's proceed to step 6:
The number 90 fits into 76 0 times, leaving a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 4970.0
The remainder is 76 after subtracting 0 from 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 7:
If we divide 760 by 90, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 4970.8
Subtract 720 from 760 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 4970.84
If we take 360 away from 400, 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.

Let's proceed to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 4970.844
Deduct 360 from 400 and we're left 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.

The final outcome is 4970.844, with a leftover of 0.004.
