20050026 ÷ 690 
Our goal is to divide 20050026 by 690.

Step 1:
If we divide 2 by 690, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
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 / 690

Going ahead to step 2:
690 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 690

Going ahead to step 3:
200 divided by 690 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 200 and we're left with 200.
Take the next digit (5) from the dividend and append it to 200, then repeat: 2005 / 690

On to step 4:
2005 divided by 690 is 2 with a remainder of 625.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1380 from 2005 and we're left with 625.
Include the next digit (0) from the dividend after 625, then repeat: 6250 / 690

Going ahead to step 5:
6250 divided by 690 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 40 after subtracting 6210 from 6250.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 690

On to step 6:
When dividing 400 by 690, we get 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 290.0
If we subtract 0 from 400, we get 400.
Bring next digit (2) of the dividend behind the 400 and repeat the process: 4002 / 690

Advancing to step 7:
If we divide 4002 by 690, we get 5 and a remainder of 552.
Record the quotient 5 as the next digit in the result. 
Result so far: 2905.0
Subtracting 3450 from 4002 leaves us with 552.
Bring next digit (6) of the dividend behind the 552 and repeat the process: 5526 / 690

Let's proceed to step 8:
The number 690 fits into 5526 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 29058.0
Subtracting 5520 from 5526 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
If we divide 60 by 690, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 29058.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
When dividing 600 by 690, we get 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 29058.0
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 29058.0, with a leftover of 0.6.
