20817402 divided by 312 
We want to figure out the number of times 20817402 can be divided by 312.

Advancing to step 1:
The number 312 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 312

Moving on to step 2:
312 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 312

Moving on to step 3:
312 can be fit into 208 0 times, resulting in a remainder of 208.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 208, we end up with 208.
Include the next digit (1) from the dividend after 208, then repeat: 2081 / 312

Going ahead to step 4:
2081 divided by 312 is 6 with a remainder of 209.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 1872 from 2081 to get 209.
Fetch the next digit (7) from the dividend, attach it to 209 and continue: 2097 / 312

Going ahead to step 5:
If we divide 2097 by 312, we get 6 and a remainder of 225.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we subtract 1872 from 2097, we get 225.
Fetch the next digit (4) from the dividend, attach it to 225 and continue: 2254 / 312

Let's proceed to step 6:
2254 divided by 312 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 667.0
Subtracting 2184 from 2254 leaves us with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 312

Let's proceed to step 7:
700 divided by 312 is 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 6672.0
If we subtract 624 from 700, we get 76.
Bring next digit (2) of the dividend behind the 76 and repeat the process: 762 / 312

Let's proceed to step 8:
When dividing 762 by 312, we get 2 with a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 66722.0
The remainder is 138 after subtracting 624 from 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 9:
1380 divided by 312 is 4 with a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 66722.4
The remainder is 132 after subtracting 1248 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 10:
312 can be fit into 1320 4 times, resulting in a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 66722.44
Subtracting 1248 from 1320 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 66722.44 with a remaining 0.072.
