20720463 ÷ 312 
Our goal is to divide 20720463 by 312.

Let's proceed to step 1:
If we divide 2 by 312, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 312

On to step 2:
The number 312 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 312

Moving on to step 3:
207 divided by 312 is 0 with a remainder of 207.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 207 and we're left with 207.
Include the next digit (2) from the dividend after 207, then repeat: 2072 / 312

On to step 4:
312 can be fit into 2072 6 times, resulting in a remainder of 200.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 1872 away from 2072, we end up with 200.
Append the next digit (0) from the dividend to 200 and continue with: 2000 / 312

Step 5:
312 can be fit into 2000 6 times, resulting in a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtracting 1872 from 2000 leaves us with 128.
Grab the next digit (4) from the dividend, add it to 128, then carry on: 1284 / 312

Let's proceed to step 6:
1284 divided by 312 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 664.0
Subtracting 1248 from 1284 leaves us with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 312

Let's proceed to step 7:
312 can be fit into 366 1 times, resulting in a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 6641.0
Subtract 312 from 366 to get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 312

Let's proceed to step 8:
543 divided by 312 is 1 with a remainder of 231.
Write down 1 as next digit of the result. 
Result so far: 66411.0
If we take 312 away from 543, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 9:
2310 divided by 312 is 7 with a remainder of 126.
The next digit of our result is 7. 
Result so far: 66411.7
Deduct 2184 from 2310 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
The number 312 fits into 1260 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 66411.74
Subtract 1248 from 1260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 312 is 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 66411.74
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
312 can be fit into 1200 3 times, resulting in a remainder of 264.
The next digit of our result is 3. 
Result so far: 66411.7403
The remainder is 264 after subtracting 936 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 13:
The number 312 fits into 2640 8 times, leaving a remainder of 144.
The next digit of our result is 8. 
Result so far: 66411.74038
Deduct 2496 from 2640 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 14:
When dividing 1440 by 312, we get 4 with a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 66411.740384
Subtract 1248 from 1440 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.

Going ahead to step 15:
312 goes into 1920 6 times with a remainder of 48.
The next digit of our result is 6. 
Result so far: 66411.7403846
If we take 1872 away from 1920, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
312 can be fit into 480 1 times, resulting in a remainder of 168.
Put 1 as the next digit of the answer. 
Result so far: 66411.74038461
If we subtract 312 from 480, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The quotient of the division is 66411.74038461, and the remainder is 1.68e-07.
