215017 ÷ 30 
We want to divide 215017 by 30.

Step 1:
30 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 30

Advancing to step 2:
If we divide 21 by 30, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 30

Step 3:
The number 30 fits into 215 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 210 from 215 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 30

Advancing to step 4:
The number 30 fits into 50 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtracting 30 from 50 leaves us with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 30

Step 5:
30 goes into 201 6 times with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 716.0
Subtract 180 from 201 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 30

On to step 6:
217 divided by 30 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 7167.0
Deduct 210 from 217 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
30 can be fit into 70 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 7167.2
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 7167.23
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 7167.233
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 7167.233 with a remaining 0.001.
