We look at the division of 20731371 by 578 
We want to divide 20731371 by 578.

Step 1:
578 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 578

Advancing to step 2:
The number 578 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
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 / 578

Step 3:
When dividing 207 by 578, we get 0 with a remainder of 207.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 207, we end up with 207.
Append the next digit (3) from the dividend to 207 and continue with: 2073 / 578

Advancing to step 4:
578 can be fit into 2073 3 times, resulting in a remainder of 339.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 1734 from 2073, we get 339.
Append the next digit (1) from the dividend to 339 and continue with: 3391 / 578

Let's proceed to step 5:
3391 divided by 578 is 5 with a remainder of 501.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we take 2890 away from 3391, we end up with 501.
Append the next digit (3) from the dividend to 501 and continue with: 5013 / 578

Let's proceed to step 6:
5013 divided by 578 is 8 with a remainder of 389.
Use 8 as the next digit of our solution. 
Result so far: 358.0
The remainder is 389 after subtracting 4624 from 5013.
Append the next digit (7) from the dividend to 389 and continue with: 3897 / 578

Moving on to step 7:
578 can be fit into 3897 6 times, resulting in a remainder of 429.
The number 6 becomes the next digit in our result. 
Result so far: 3586.0
Subtracting 3468 from 3897 leaves us with 429.
Take the next digit (1) from the dividend and append it to 429, then repeat: 4291 / 578

Let's proceed to step 8:
If we divide 4291 by 578, we get 7 and a remainder of 245.
Write down 7 as next digit of the result. 
Result so far: 35867.0
Deduct 4046 from 4291 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 9:
578 can be fit into 2450 4 times, resulting in a remainder of 138.
Put 4 as the next digit of the answer. 
Result so far: 35867.4
Subtracting 2312 from 2450 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.

Let's proceed to step 10:
1380 divided by 578 is 2 with a remainder of 224.
The next digit of our result is 2. 
Result so far: 35867.42
If we subtract 1156 from 1380, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 11:
2240 divided by 578 is 3 with a remainder of 506.
The next digit of our result is 3. 
Result so far: 35867.423
Subtract 1734 from 2240 to get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 12:
5060 divided by 578 is 8 with a remainder of 436.
Put 8 as the next digit of the answer. 
Result so far: 35867.4238
Subtract 4624 from 5060 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 13:
The number 578 fits into 4360 7 times, leaving a remainder of 314.
Write down 7 as next digit of the result. 
Result so far: 35867.42387
If we take 4046 away from 4360, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 14:
When dividing 3140 by 578, we get 5 with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 35867.423875
The remainder is 250 after subtracting 2890 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 15:
2500 divided by 578 is 4 with a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 35867.4238754
The remainder is 188 after subtracting 2312 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 16:
578 goes into 1880 3 times with a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 35867.42387543
Subtract 1734 from 1880 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The quotient of the division is 35867.42387543, and the remainder is 1.46e-07.
