358363 ÷ 90 
We want to divide 358363 by 90.

Going ahead to step 1:
90 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 90

Step 2:
90 goes into 35 0 times with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 90

Advancing to step 3:
90 can be fit into 358 3 times, resulting in a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 270 from 358 to get 88.
Fetch the next digit (3) from the dividend, attach it to 88 and continue: 883 / 90

Moving on to step 4:
When dividing 883 by 90, we get 9 with a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtracting 810 from 883 leaves us with 73.
Fetch the next digit (6) from the dividend, attach it to 73 and continue: 736 / 90

Moving on to step 5:
The number 90 fits into 736 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 398.0
If we take 720 away from 736, we end up with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 90

Step 6:
When dividing 163 by 90, we get 1 with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 3981.0
If we take 90 away from 163, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
90 can be fit into 730 8 times, resulting in a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 3981.8
Deduct 720 from 730 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 3981.81
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 90 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 3981.811
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 3981.811 with a remaining 0.001.
