20564210 ÷ 680 
Our goal is to divide 20564210 by 680.

Moving on to step 1:
If we divide 2 by 680, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 680

On to step 2:
680 goes into 20 0 times with 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 (5) of the dividend behind the 20 and repeat the process: 205 / 680

Moving on to step 3:
680 can be fit into 205 0 times, resulting in a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 205, we get 205.
Fetch the next digit (6) from the dividend, attach it to 205 and continue: 2056 / 680

Let's proceed to step 4:
If we divide 2056 by 680, we get 3 and a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 2040 away from 2056, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 680

On to step 5:
680 can be fit into 164 0 times, resulting in a remainder of 164.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 164 to get 164.
Fetch the next digit (2) from the dividend, attach it to 164 and continue: 1642 / 680

Going ahead to step 6:
When dividing 1642 by 680, we get 2 with a remainder of 282.
Put 2 as the next digit of the answer. 
Result so far: 302.0
If we subtract 1360 from 1642, we get 282.
Include the next digit (1) from the dividend after 282, then repeat: 2821 / 680

Going ahead to step 7:
680 can be fit into 2821 4 times, resulting in a remainder of 101.
Record the quotient 4 as the next digit in the result. 
Result so far: 3024.0
Subtract 2720 from 2821 to get 101.
Fetch the next digit (0) from the dividend, attach it to 101 and continue: 1010 / 680

Let's proceed to step 8:
The number 680 fits into 1010 1 times, leaving a remainder of 330.
Put 1 as the next digit of the answer. 
Result so far: 30241.0
The remainder is 330 after subtracting 680 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 9:
3300 divided by 680 is 4 with a remainder of 580.
The next digit of our result is 4. 
Result so far: 30241.4
Deduct 2720 from 3300 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 10:
The number 680 fits into 5800 8 times, leaving a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 30241.48
Deduct 5440 from 5800 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 11:
If we divide 3600 by 680, we get 5 and a remainder of 200.
The next digit of our result is 5. 
Result so far: 30241.485
Deduct 3400 from 3600 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
2000 divided by 680 is 2 with a remainder of 640.
Use 2 as the next digit of our solution. 
Result so far: 30241.4852
Subtracting 1360 from 2000 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 13:
If we divide 6400 by 680, we get 9 and a remainder of 280.
Put 9 as the next digit of the answer. 
Result so far: 30241.48529
If we take 6120 away from 6400, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
If we divide 2800 by 680, we get 4 and a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 30241.485294
If we subtract 2720 from 2800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
If we divide 800 by 680, we get 1 and a remainder of 120.
The next digit of our result is 1. 
Result so far: 30241.4852941
If we take 680 away from 800, we end up 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 16:
680 can be fit into 1200 1 times, resulting in a remainder of 520.
Record the quotient 1 as the next digit in the result. 
Result so far: 30241.48529411
The remainder is 520 after subtracting 680 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

In conclusion, the division gives 30241.48529411 with a balance of 5.2e-07.
