3940554 divided by 306 
We want to divide 3940554 by 306.

On to step 1:
306 can be fit into 3 0 times, resulting in 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.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 306

On to step 2:
39 divided by 306 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 306

Moving on to step 3:
The number 306 fits into 394 1 times, leaving a remainder of 88.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 306 from 394 and we're left with 88.
Include the next digit (0) from the dividend after 88, then repeat: 880 / 306

Moving on to step 4:
306 goes into 880 2 times with a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 268 after subtracting 612 from 880.
Fetch the next digit (5) from the dividend, attach it to 268 and continue: 2685 / 306

On to step 5:
306 can be fit into 2685 8 times, resulting in a remainder of 237.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtract 2448 from 2685 to get 237.
Fetch the next digit (5) from the dividend, attach it to 237 and continue: 2375 / 306

Advancing to step 6:
When dividing 2375 by 306, we get 7 with a remainder of 233.
The next digit of our result is 7. 
Result so far: 1287.0
If we take 2142 away from 2375, we end up with 233.
Bring next digit (4) of the dividend behind the 233 and repeat the process: 2334 / 306

Let's proceed to step 7:
If we divide 2334 by 306, we get 7 and a remainder of 192.
The number 7 becomes the next digit in our result. 
Result so far: 12877.0
Subtract 2142 from 2334 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 8:
306 can be fit into 1920 6 times, resulting in a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 12877.6
If we subtract 1836 from 1920, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 9:
The number 306 fits into 840 2 times, leaving a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 12877.62
Subtracting 612 from 840 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 10:
2280 divided by 306 is 7 with a remainder of 138.
Write down 7 as next digit of the result. 
Result so far: 12877.627
Subtracting 2142 from 2280 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 11:
306 can be fit into 1380 4 times, resulting in a remainder of 156.
Use 4 as the next digit of our solution. 
Result so far: 12877.6274
If we take 1224 away from 1380, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 12:
306 can be fit into 1560 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 12877.62745
Deduct 1530 from 1560 and we're left 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.

Step 13:
The number 306 fits into 300 0 times, leaving a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 12877.62745
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 14:
When dividing 3000 by 306, we get 9 with a remainder of 246.
Use 9 as the next digit of our solution. 
Result so far: 12877.6274509
If we subtract 2754 from 3000, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 15:
The number 306 fits into 2460 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 12877.62745098
The remainder is 12 after subtracting 2448 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 12877.62745098 and a remainder of 1.2e-08.
