We're dividing 945639 by 30 
Let's see how many times 30 fits into 945639.

Advancing to step 1:
9 divided by 30 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 30

On to step 2:
The number 30 fits into 94 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 4 after subtracting 90 from 94.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 30

Let's proceed to step 3:
30 goes into 45 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 30 from 45, we get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 30

Going ahead to step 4:
30 goes into 156 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 315.0
If we take 150 away from 156, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 30

On to step 5:
When dividing 63 by 30, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 3152.0
If we take 60 away from 63, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 30

Advancing to step 6:
The number 30 fits into 39 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 31521.0
Deduct 30 from 39 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 30 fits into 90 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 31521.3
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31521.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31521.3
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 31521.3 with a remainder of 0.0.
