100973 ÷ 30 
Let's see how many times 30 fits into 100973.

Moving on to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 30

Moving on to step 2:
The number 30 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 30

Step 3:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 90 from 100 and we're left with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 30

Going ahead to step 4:
30 can be fit into 109 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 19 after subtracting 90 from 109.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 30

Moving on to step 5:
When dividing 197 by 30, we get 6 with a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 336.0
Deduct 180 from 197 and we're left with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 30

Step 6:
If we divide 173 by 30, we get 5 and a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 3365.0
If we take 150 away from 173, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
If we divide 230 by 30, we get 7 and a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 3365.7
Subtracting 210 from 230 leaves us 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 8:
30 goes into 200 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 3365.76
Subtracting 180 from 200 leaves us 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 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 3365.766
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.

Our division results in 3365.766 with a remaining 0.002.
