20900649 divided by 689 
Let's see how many times 689 fits into 20900649.

Going ahead to step 1:
689 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
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 / 689

Advancing to step 2:
20 divided by 689 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 689

Moving on to step 3:
When dividing 209 by 689, we get 0 with a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 209, we end up with 209.
Include the next digit (0) from the dividend after 209, then repeat: 2090 / 689

Step 4:
689 goes into 2090 3 times with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 2067 from 2090 and we're left with 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 689

Moving on to step 5:
689 can be fit into 230 0 times, resulting in a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 230, we end up with 230.
Take the next digit (6) from the dividend and append it to 230, then repeat: 2306 / 689

Advancing to step 6:
The number 689 fits into 2306 3 times, leaving a remainder of 239.
Record the quotient 3 as the next digit in the result. 
Result so far: 303.0
If we subtract 2067 from 2306, we get 239.
Append the next digit (4) from the dividend to 239 and continue with: 2394 / 689

Step 7:
When dividing 2394 by 689, we get 3 with a remainder of 327.
Record the quotient 3 as the next digit in the result. 
Result so far: 3033.0
Subtracting 2067 from 2394 leaves us with 327.
Take the next digit (9) from the dividend and append it to 327, then repeat: 3279 / 689

Moving on to step 8:
If we divide 3279 by 689, we get 4 and a remainder of 523.
The number 4 becomes the next digit in our result. 
Result so far: 30334.0
If we subtract 2756 from 3279, we get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Advancing to step 9:
689 can be fit into 5230 7 times, resulting in a remainder of 407.
Use 7 as the next digit of our solution. 
Result so far: 30334.7
If we subtract 4823 from 5230, we get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 10:
689 can be fit into 4070 5 times, resulting in a remainder of 625.
Put 5 as the next digit of the answer. 
Result so far: 30334.75
If we subtract 3445 from 4070, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 11:
When dividing 6250 by 689, we get 9 with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 30334.759
The remainder is 49 after subtracting 6201 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
490 divided by 689 is 0 with a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 30334.759
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 13:
689 can be fit into 4900 7 times, resulting in a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 30334.75907
If we subtract 4823 from 4900, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 14:
689 can be fit into 770 1 times, resulting in a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 30334.759071
Subtract 689 from 770 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 15:
689 can be fit into 810 1 times, resulting in a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 30334.7590711
The remainder is 121 after subtracting 689 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

After the division, we end up with 30334.7590711 and a remainder of 1.21e-06.
