Let's divide 251603 by 30
We want to figure out the number of times 251603 can be divided by 30.

Let's proceed to step 1:
30 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 30

Let's proceed to step 2:
30 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 30

On to step 3:
30 can be fit into 251 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 240 from 251, we get 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 30

Moving on to step 4:
The number 30 fits into 116 3 times, leaving a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Deduct 90 from 116 and we're left with 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 30

Let's proceed to step 5:
The number 30 fits into 260 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 838.0
If we subtract 240 from 260, we get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 30

Moving on to step 6:
The number 30 fits into 203 6 times, leaving a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 8386.0
The remainder is 23 after subtracting 180 from 203.
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:
The number 30 fits into 230 7 times, leaving a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 8386.7
If we subtract 210 from 230, 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.

Going ahead to step 8:
30 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 8386.76
Subtract 180 from 200 to 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 9:
200 divided by 30 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 8386.766
If we take 180 away from 200, 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.

The final outcome is 8386.766, with a leftover of 0.002.
