We're dividing 30171284 by 749 
Our goal is to divide 30171284 by 749.

Moving on to step 1:
3 divided by 749 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 749

Let's proceed to step 2:
If we divide 30 by 749, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 749

Going ahead to step 3:
749 can be fit into 301 0 times, resulting in a remainder of 301.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 301 leaves us with 301.
Include the next digit (7) from the dividend after 301, then repeat: 3017 / 749

Advancing to step 4:
749 goes into 3017 4 times with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2996 from 3017 to get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 749

Moving on to step 5:
211 divided by 749 is 0 with a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 211, we get 211.
Bring next digit (2) of the dividend behind the 211 and repeat the process: 2112 / 749

Going ahead to step 6:
749 goes into 2112 2 times with a remainder of 614.
The next digit of our result is 2. 
Result so far: 402.0
Deduct 1498 from 2112 and we're left with 614.
Bring next digit (8) of the dividend behind the 614 and repeat the process: 6148 / 749

Let's proceed to step 7:
When dividing 6148 by 749, we get 8 with a remainder of 156.
The next digit of our result is 8. 
Result so far: 4028.0
If we subtract 5992 from 6148, we get 156.
Grab the next digit (4) from the dividend, add it to 156, then carry on: 1564 / 749

On to step 8:
The number 749 fits into 1564 2 times, leaving a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 40282.0
If we subtract 1498 from 1564, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
If we divide 660 by 749, we get 0 and a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 40282.0
If we take 0 away from 660, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 10:
If we divide 6600 by 749, we get 8 and a remainder of 608.
The number 8 becomes the next digit in our result. 
Result so far: 40282.08
Subtract 5992 from 6600 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 11:
The number 749 fits into 6080 8 times, leaving a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 40282.088
Subtracting 5992 from 6080 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final outcome is 40282.088, with a leftover of 0.0088.
