We're dividing 21608360 by 689 
We want to divide 21608360 by 689.

Step 1:
When dividing 2 by 689, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 689

On to step 2:
When dividing 21 by 689, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 689

Going ahead to step 3:
216 divided by 689 is 0 with a remainder of 216.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Grab the next digit (0) from the dividend, add it to 216, then carry on: 2160 / 689

Let's proceed to step 4:
2160 divided by 689 is 3 with a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 93 after subtracting 2067 from 2160.
Bring next digit (8) of the dividend behind the 93 and repeat the process: 938 / 689

Let's proceed to step 5:
689 goes into 938 1 times with a remainder of 249.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 689 away from 938, we end up with 249.
Take the next digit (3) from the dividend and append it to 249, then repeat: 2493 / 689

On to step 6:
When dividing 2493 by 689, we get 3 with a remainder of 426.
Use 3 as the next digit of our solution. 
Result so far: 313.0
Subtracting 2067 from 2493 leaves us with 426.
Bring next digit (6) of the dividend behind the 426 and repeat the process: 4266 / 689

On to step 7:
If we divide 4266 by 689, we get 6 and a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 3136.0
If we take 4134 away from 4266, we end up with 132.
Take the next digit (0) from the dividend and append it to 132, then repeat: 1320 / 689

Moving on to step 8:
The number 689 fits into 1320 1 times, leaving a remainder of 631.
Record the quotient 1 as the next digit in the result. 
Result so far: 31361.0
The remainder is 631 after subtracting 689 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Let's proceed to step 9:
6310 divided by 689 is 9 with a remainder of 109.
Write down 9 as next digit of the result. 
Result so far: 31361.9
Subtracting 6201 from 6310 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 10:
The number 689 fits into 1090 1 times, leaving a remainder of 401.
Write down 1 as next digit of the result. 
Result so far: 31361.91
If we subtract 689 from 1090, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 11:
689 goes into 4010 5 times with a remainder of 565.
The number 5 becomes the next digit in our result. 
Result so far: 31361.915
If we subtract 3445 from 4010, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 12:
When dividing 5650 by 689, we get 8 with a remainder of 138.
The next digit of our result is 8. 
Result so far: 31361.9158
If we subtract 5512 from 5650, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 13:
689 goes into 1380 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 31361.91582
If we subtract 1378 from 1380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
689 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 31361.91582
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 15:
If we divide 200 by 689, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 31361.91582
Subtracting 0 from 200 leaves us 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.

The quotient of the division is 31361.91582, and the remainder is 2e-06.
