We're dividing 20157445 by 306 
Let's see how many times 306 fits into 20157445.

Moving on to step 1:
2 divided by 306 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 306

Moving on to step 2:
306 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 306

Let's proceed to step 3:
The number 306 fits into 201 0 times, leaving a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 201 to get 201.
Grab the next digit (5) from the dividend, add it to 201, then carry on: 2015 / 306

Step 4:
The number 306 fits into 2015 6 times, leaving a remainder of 179.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 179 after subtracting 1836 from 2015.
Take the next digit (7) from the dividend and append it to 179, then repeat: 1797 / 306

On to step 5:
306 goes into 1797 5 times with a remainder of 267.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Subtracting 1530 from 1797 leaves us with 267.
Append the next digit (4) from the dividend to 267 and continue with: 2674 / 306

On to step 6:
306 goes into 2674 8 times with a remainder of 226.
Use 8 as the next digit of our solution. 
Result so far: 658.0
Subtract 2448 from 2674 to get 226.
Fetch the next digit (4) from the dividend, attach it to 226 and continue: 2264 / 306

Going ahead to step 7:
If we divide 2264 by 306, we get 7 and a remainder of 122.
Record the quotient 7 as the next digit in the result. 
Result so far: 6587.0
Subtract 2142 from 2264 to get 122.
Fetch the next digit (5) from the dividend, attach it to 122 and continue: 1225 / 306

Advancing to step 8:
306 goes into 1225 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 65874.0
Subtracting 1224 from 1225 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
306 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 65874.0
If we subtract 0 from 10, we 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.

Advancing to step 10:
When dividing 100 by 306, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 65874.0
Subtract 0 from 100 to 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.

Our division results in 65874.0 with a remaining 0.1.
