We're dividing 39684565 by 310 
We want to divide 39684565 by 310.

On to step 1:
310 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 310

Let's proceed to step 2:
When dividing 39 by 310, we get 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 (6) from the dividend, attach it to 39 and continue: 396 / 310

On to step 3:
310 can be fit into 396 1 times, resulting in a remainder of 86.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 310 from 396 leaves us with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 310

Advancing to step 4:
The number 310 fits into 868 2 times, leaving a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 620 away from 868, we end up with 248.
Include the next digit (4) from the dividend after 248, then repeat: 2484 / 310

Advancing to step 5:
The number 310 fits into 2484 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
The remainder is 4 after subtracting 2480 from 2484.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 310

Going ahead to step 6:
The number 310 fits into 45 0 times, leaving a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 1280.0
If we take 0 away from 45, we end up with 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 310

Step 7:
310 can be fit into 456 1 times, resulting in a remainder of 146.
The number 1 becomes the next digit in our result. 
Result so far: 12801.0
The remainder is 146 after subtracting 310 from 456.
Take the next digit (5) from the dividend and append it to 146, then repeat: 1465 / 310

Let's proceed to step 8:
When dividing 1465 by 310, we get 4 with a remainder of 225.
Write down 4 as next digit of the result. 
Result so far: 128014.0
Subtracting 1240 from 1465 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 9:
310 goes into 2250 7 times with a remainder of 80.
Record the quotient 7 as the next digit in the result. 
Result so far: 128014.7
Subtracting 2170 from 2250 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
The number 310 fits into 800 2 times, leaving a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 128014.72
Subtract 620 from 800 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
1800 divided by 310 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 128014.725
If we take 1550 away from 1800, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 12:
The number 310 fits into 2500 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 128014.7258
Subtract 2480 from 2500 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
310 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 128014.7258
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 14:
The number 310 fits into 2000 6 times, leaving a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 128014.725806
Subtract 1860 from 2000 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 15:
310 can be fit into 1400 4 times, resulting in a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 128014.7258064
If we take 1240 away from 1400, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
The number 310 fits into 1600 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 128014.72580645
Subtracting 1550 from 1600 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 128014.72580645 with a remaining 5e-08.
