We're dividing 31648540 by 689 
Let's see how many times 689 fits into 31648540.

Let's proceed to step 1:
3 divided by 689 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 689

Let's proceed to step 2:
31 divided by 689 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 689

Advancing to step 3:
689 goes into 316 0 times with a remainder of 316.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 316, we get 316.
Include the next digit (4) from the dividend after 316, then repeat: 3164 / 689

On to step 4:
When dividing 3164 by 689, we get 4 with a remainder of 408.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2756 from 3164, we get 408.
Include the next digit (8) from the dividend after 408, then repeat: 4088 / 689

On to step 5:
The number 689 fits into 4088 5 times, leaving a remainder of 643.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 3445 from 4088 and we're left with 643.
Bring next digit (5) of the dividend behind the 643 and repeat the process: 6435 / 689

Going ahead to step 6:
The number 689 fits into 6435 9 times, leaving a remainder of 234.
Write down 9 as next digit of the result. 
Result so far: 459.0
Deduct 6201 from 6435 and we're left with 234.
Include the next digit (4) from the dividend after 234, then repeat: 2344 / 689

Moving on to step 7:
689 goes into 2344 3 times with a remainder of 277.
The next digit of our result is 3. 
Result so far: 4593.0
Subtracting 2067 from 2344 leaves us with 277.
Bring next digit (0) of the dividend behind the 277 and repeat the process: 2770 / 689

Moving on to step 8:
689 can be fit into 2770 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 45934.0
If we take 2756 away from 2770, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
When dividing 140 by 689, we get 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 45934.0
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
689 can be fit into 1400 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 45934.02
Subtracting 1378 from 1400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
If we divide 220 by 689, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 45934.02
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 12:
The number 689 fits into 2200 3 times, leaving a remainder of 133.
The number 3 becomes the next digit in our result. 
Result so far: 45934.0203
If we subtract 2067 from 2200, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 13:
689 goes into 1330 1 times with a remainder of 641.
Write down 1 as next digit of the result. 
Result so far: 45934.02031
Subtracting 689 from 1330 leaves us with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Advancing to step 14:
The number 689 fits into 6410 9 times, leaving a remainder of 209.
Put 9 as the next digit of the answer. 
Result so far: 45934.020319
Subtract 6201 from 6410 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 15:
If we divide 2090 by 689, we get 3 and a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 45934.0203193
If we subtract 2067 from 2090, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 16:
689 goes into 230 0 times with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 45934.0203193
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final outcome is 45934.0203193, with a leftover of 2.3e-07.
