374628 ÷ 30 
Let's see how many times 30 fits into 374628.

Going ahead to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 30

Moving on to step 2:
30 can be fit into 37 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 30 from 37, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 30

Going ahead to step 3:
If we divide 74 by 30, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 60 from 74, we get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 30

Going ahead to step 4:
30 goes into 146 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Subtracting 120 from 146 leaves us with 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 30

Advancing to step 5:
262 divided by 30 is 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 1248.0
Deduct 240 from 262 and we're left with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 30

Let's proceed to step 6:
30 can be fit into 228 7 times, resulting in a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 12487.0
The remainder is 18 after subtracting 210 from 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
When dividing 180 by 30, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 12487.6
If we subtract 180 from 180, 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.

Step 8:
0 divided by 30 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12487.6
Subtract 0 from 0 to 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.

Moving on to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12487.6
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 12487.6, with a leftover of 0.0.
