We look at the division of 30139306 by 918 
We want to divide 30139306 by 918.

On to step 1:
The number 918 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
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 918

Step 2:
30 divided by 918 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 918

Advancing to step 3:
When dividing 301 by 918, we get 0 with a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 301, we get 301.
Grab the next digit (3) from the dividend, add it to 301, then carry on: 3013 / 918

Moving on to step 4:
918 goes into 3013 3 times with a remainder of 259.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 2754 from 3013 to get 259.
Grab the next digit (9) from the dividend, add it to 259, then carry on: 2599 / 918

Going ahead to step 5:
The number 918 fits into 2599 2 times, leaving a remainder of 763.
Put 2 as the next digit of the answer. 
Result so far: 32.0
The remainder is 763 after subtracting 1836 from 2599.
Take the next digit (3) from the dividend and append it to 763, then repeat: 7633 / 918

Let's proceed to step 6:
918 goes into 7633 8 times with a remainder of 289.
Put 8 as the next digit of the answer. 
Result so far: 328.0
Subtract 7344 from 7633 to get 289.
Fetch the next digit (0) from the dividend, attach it to 289 and continue: 2890 / 918

On to step 7:
The number 918 fits into 2890 3 times, leaving a remainder of 136.
Write down 3 as next digit of the result. 
Result so far: 3283.0
Subtracting 2754 from 2890 leaves us with 136.
Append the next digit (6) from the dividend to 136 and continue with: 1366 / 918

On to step 8:
918 goes into 1366 1 times with a remainder of 448.
Use 1 as the next digit of our solution. 
Result so far: 32831.0
Deduct 918 from 1366 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 9:
918 can be fit into 4480 4 times, resulting in a remainder of 808.
Write down 4 as next digit of the result. 
Result so far: 32831.4
The remainder is 808 after subtracting 3672 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Going ahead to step 10:
The number 918 fits into 8080 8 times, leaving a remainder of 736.
Put 8 as the next digit of the answer. 
Result so far: 32831.48
Deduct 7344 from 8080 and we're left with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 11:
If we divide 7360 by 918, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 32831.488
If we take 7344 away from 7360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 32831.488 and a remainder of 0.0016.
