We're dividing 454161 by 90 
We want to divide 454161 by 90.

Advancing to step 1:
90 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 90

Step 2:
90 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 90

On to step 3:
90 goes into 454 5 times with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 450 from 454 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 90

Step 4:
The number 90 fits into 41 0 times, leaving a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 41 and we're left with 41.
Append the next digit (6) from the dividend to 41 and continue with: 416 / 90

On to step 5:
90 can be fit into 416 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 504.0
If we subtract 360 from 416, we get 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 90

Advancing to step 6:
90 goes into 561 6 times with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 5046.0
Subtracting 540 from 561 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
When dividing 210 by 90, we get 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 5046.2
Subtract 180 from 210 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 90 is 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 5046.23
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
If we divide 300 by 90, we get 3 and a remainder of 30.
The next digit of our result is 3. 
Result so far: 5046.233
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 5046.233 with a balance of 0.003.
