90659531 ÷ 30 
We want to divide 90659531 by 30.

Advancing to step 1:
If we divide 9 by 30, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 30

Let's proceed to step 2:
The number 30 fits into 90 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 90 from 90 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 30

Let's proceed to step 3:
The number 30 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 30

Step 4:
30 goes into 65 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 302.0
If we take 60 away from 65, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 30

Going ahead to step 5:
59 divided by 30 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 3021.0
Deduct 30 from 59 and we're left with 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 30

Going ahead to step 6:
If we divide 295 by 30, we get 9 and a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 30219.0
Subtract 270 from 295 to get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 30

Moving on to step 7:
30 goes into 253 8 times with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 302198.0
If we take 240 away from 253, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 30

Step 8:
If we divide 131 by 30, we get 4 and a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 3021984.0
The remainder is 11 after subtracting 120 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
If we divide 110 by 30, we get 3 and a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 3021984.3
If we take 90 away from 110, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 3021984.36
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 3021984.366
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 3021984.366 with a remainder of 0.002.
