We're dividing 30143475 by 491 
We want to divide 30143475 by 491.

On to step 1:
491 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 491

Moving on to step 2:
The number 491 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 491

Step 3:
491 goes into 301 0 times with a remainder of 301.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 301 to get 301.
Take the next digit (4) from the dividend and append it to 301, then repeat: 3014 / 491

Moving on to step 4:
491 goes into 3014 6 times with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 2946 from 3014 and we're left with 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 491

Going ahead to step 5:
When dividing 683 by 491, we get 1 with a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we subtract 491 from 683, we get 192.
Take the next digit (4) from the dividend and append it to 192, then repeat: 1924 / 491

Advancing to step 6:
The number 491 fits into 1924 3 times, leaving a remainder of 451.
The number 3 becomes the next digit in our result. 
Result so far: 613.0
Subtract 1473 from 1924 to get 451.
Append the next digit (7) from the dividend to 451 and continue with: 4517 / 491

Going ahead to step 7:
4517 divided by 491 is 9 with a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 6139.0
If we subtract 4419 from 4517, we get 98.
Grab the next digit (5) from the dividend, add it to 98, then carry on: 985 / 491

Advancing to step 8:
The number 491 fits into 985 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 61392.0
Subtracting 982 from 985 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
491 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 61392.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
The number 491 fits into 300 0 times, leaving a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 61392.0
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 61392.0, with a leftover of 0.3.
