52318912 ÷ 90 
We want to divide 52318912 by 90.

Let's proceed to step 1:
5 divided by 90 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 90

Let's proceed to step 2:
90 can be fit into 52 0 times, resulting in a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (3) from the dividend after 52, then repeat: 523 / 90

Advancing to step 3:
90 goes into 523 5 times with a remainder of 73.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 450 from 523 leaves us with 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 90

Advancing to step 4:
731 divided by 90 is 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtracting 720 from 731 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 90

Going ahead to step 5:
118 divided by 90 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 581.0
The remainder is 28 after subtracting 90 from 118.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 90

Moving on to step 6:
90 can be fit into 289 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 5813.0
The remainder is 19 after subtracting 270 from 289.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 90

On to step 7:
90 can be fit into 191 2 times, resulting in a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 58132.0
Deduct 180 from 191 and we're left with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 90

Step 8:
90 can be fit into 112 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 581321.0
The remainder is 22 after subtracting 90 from 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
90 can be fit into 220 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 581321.2
Subtract 180 from 220 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.

Going ahead to step 10:
When dividing 400 by 90, we get 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 581321.24
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.

Advancing to step 11:
The number 90 fits into 400 4 times, leaving a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 581321.244
Subtract 360 from 400 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.

Our division results in 581321.244 with a remaining 0.004.
