We look at the division of 40292425 by 306 
We want to divide 40292425 by 306.

On to step 1:
The number 306 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 306

Step 2:
The number 306 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 306

Step 3:
306 goes into 402 1 times with a remainder of 96.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 306 from 402, we get 96.
Grab the next digit (9) from the dividend, add it to 96, then carry on: 969 / 306

Let's proceed to step 4:
306 can be fit into 969 3 times, resulting in a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 918 from 969 leaves us with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 306

Going ahead to step 5:
512 divided by 306 is 1 with a remainder of 206.
Write down 1 as next digit of the result. 
Result so far: 131.0
If we take 306 away from 512, we end up with 206.
Bring next digit (4) of the dividend behind the 206 and repeat the process: 2064 / 306

Moving on to step 6:
306 can be fit into 2064 6 times, resulting in a remainder of 228.
Put 6 as the next digit of the answer. 
Result so far: 1316.0
If we subtract 1836 from 2064, we get 228.
Grab the next digit (2) from the dividend, add it to 228, then carry on: 2282 / 306

Step 7:
The number 306 fits into 2282 7 times, leaving a remainder of 140.
Write down 7 as next digit of the result. 
Result so far: 13167.0
The remainder is 140 after subtracting 2142 from 2282.
Fetch the next digit (5) from the dividend, attach it to 140 and continue: 1405 / 306

Let's proceed to step 8:
The number 306 fits into 1405 4 times, leaving a remainder of 181.
Record the quotient 4 as the next digit in the result. 
Result so far: 131674.0
Subtract 1224 from 1405 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 9:
The number 306 fits into 1810 5 times, leaving a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 131674.5
Subtract 1530 from 1810 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 10:
If we divide 2800 by 306, we get 9 and a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 131674.59
Subtracting 2754 from 2800 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
460 divided by 306 is 1 with a remainder of 154.
Record the quotient 1 as the next digit in the result. 
Result so far: 131674.591
The remainder is 154 after subtracting 306 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 12:
306 can be fit into 1540 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 131674.5915
Subtract 1530 from 1540 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.

Let's proceed to step 13:
If we divide 100 by 306, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 131674.5915
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
If we divide 1000 by 306, we get 3 and a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 131674.591503
Subtracting 918 from 1000 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 15:
When dividing 820 by 306, we get 2 with a remainder of 208.
Use 2 as the next digit of our solution. 
Result so far: 131674.5915032
If we subtract 612 from 820, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 16:
The number 306 fits into 2080 6 times, leaving a remainder of 244.
Put 6 as the next digit of the answer. 
Result so far: 131674.59150326
Deduct 1836 from 2080 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final outcome is 131674.59150326, with a leftover of 2.44e-07.
