373670 divided by 30 
We want to figure out the number of times 373670 can be divided by 30.

Step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 30

On to step 2:
The number 30 fits into 37 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 30 from 37 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 30

On to step 3:
The number 30 fits into 73 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 13 after subtracting 60 from 73.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 30

Step 4:
136 divided by 30 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we subtract 120 from 136, we get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 30

On to step 5:
167 divided by 30 is 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 1245.0
Subtracting 150 from 167 leaves us with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 30

Step 6:
170 divided by 30 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 12455.0
If we take 150 away from 170, 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.

Step 7:
30 goes into 200 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 12455.6
If we subtract 180 from 200, we get 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:
When dividing 200 by 30, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 12455.66
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 12455.66 and a remainder of 0.02.
