901730 divided by 30 
We're looking to find how many times 30 goes into 901730.

Advancing to step 1:
9 divided by 30 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 30

Moving on to step 2:
If we divide 90 by 30, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 90 from 90 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 30

Step 3:
1 divided by 30 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 30

Let's proceed to step 4:
30 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 300.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 30

On to step 5:
When dividing 173 by 30, we get 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 3005.0
Deduct 150 from 173 and we're left with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 30

Step 6:
When dividing 230 by 30, we get 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 30057.0
Deduct 210 from 230 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.

On to step 7:
200 divided by 30 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 30057.6
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.

Moving on to step 8:
200 divided by 30 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 30057.66
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 outcome is 30057.66, with a leftover of 0.02.
