373644 ÷ 30 
We want to divide 373644 by 30.

Advancing to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 30

On to step 2:
If we divide 37 by 30, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 30 from 37, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 30

Step 3:
30 can be fit into 73 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 60 from 73 leaves us with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 30

Going ahead to step 4:
When dividing 136 by 30, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Deduct 120 from 136 and we're left with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 30

Step 5:
164 divided by 30 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 1245.0
Subtract 150 from 164 to get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 30

Advancing to step 6:
144 divided by 30 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 12454.0
The remainder is 24 after subtracting 120 from 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
30 can be fit into 240 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 12454.8
Subtracting 240 from 240 leaves us 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.

Advancing to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12454.8
Subtracting 0 from 0 leaves us 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.

On to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12454.8
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 outcome is 12454.8, with a leftover of 0.0.
