Let's divide 377749 by 30
We want to figure out the number of times 377749 can be divided by 30.

Going ahead to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 30

Advancing to step 2:
If we divide 37 by 30, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
If we take 30 away from 37, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 30

On to step 3:
30 can be fit into 77 2 times, resulting in a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 17 after subtracting 60 from 77.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 30

Step 4:
If we divide 177 by 30, we get 5 and a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Subtract 150 from 177 to get 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 30

Let's proceed to step 5:
If we divide 274 by 30, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 1259.0
Subtract 270 from 274 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 30

Going ahead to step 6:
30 can be fit into 49 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 12591.0
Subtracting 30 from 49 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 30 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 12591.6
Subtract 180 from 190 to get 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: 12591.63
Deduct 90 from 100 and we're left 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:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 12591.633
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 12591.633 with a remainder of 0.001.
