90016594 ÷ 231 
We want to divide 90016594 by 231.

Moving on to step 1:
9 divided by 231 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 231

Step 2:
90 divided by 231 is 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 231

Let's proceed to step 3:
If we divide 900 by 231, we get 3 and a remainder of 207.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 693 from 900 and we're left with 207.
Append the next digit (1) from the dividend to 207 and continue with: 2071 / 231

Moving on to step 4:
If we divide 2071 by 231, we get 8 and a remainder of 223.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 1848 away from 2071, we end up with 223.
Append the next digit (6) from the dividend to 223 and continue with: 2236 / 231

Let's proceed to step 5:
When dividing 2236 by 231, we get 9 with a remainder of 157.
Write down 9 as next digit of the result. 
Result so far: 389.0
Subtract 2079 from 2236 to get 157.
Take the next digit (5) from the dividend and append it to 157, then repeat: 1575 / 231

On to step 6:
1575 divided by 231 is 6 with a remainder of 189.
Write down 6 as next digit of the result. 
Result so far: 3896.0
If we subtract 1386 from 1575, we get 189.
Take the next digit (9) from the dividend and append it to 189, then repeat: 1899 / 231

Going ahead to step 7:
231 can be fit into 1899 8 times, resulting in a remainder of 51.
The next digit of our result is 8. 
Result so far: 38968.0
Deduct 1848 from 1899 and we're left with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 231

Let's proceed to step 8:
514 divided by 231 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 389682.0
The remainder is 52 after subtracting 462 from 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
When dividing 520 by 231, we get 2 with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 389682.2
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
When dividing 580 by 231, we get 2 with a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 389682.22
Subtract 462 from 580 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The final result is 389682.22 with a remainder of 0.118.
