Let's divide 3169900 by 689
We want to divide 3169900 by 689.

On to step 1:
If we divide 3 by 689, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 689

Step 2:
689 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 689

Moving on to step 3:
The number 689 fits into 316 0 times, leaving a remainder of 316.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 316 leaves us with 316.
Include the next digit (9) from the dividend after 316, then repeat: 3169 / 689

Advancing to step 4:
The number 689 fits into 3169 4 times, leaving a remainder of 413.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2756 from 3169 to get 413.
Bring next digit (9) of the dividend behind the 413 and repeat the process: 4139 / 689

On to step 5:
If we divide 4139 by 689, we get 6 and a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 4134 from 4139 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 689

Advancing to step 6:
If we divide 50 by 689, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 460.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 689

Going ahead to step 7:
500 divided by 689 is 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 4600.0
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 8:
689 goes into 5000 7 times with a remainder of 177.
The number 7 becomes the next digit in our result. 
Result so far: 4600.7
If we take 4823 away from 5000, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 9:
689 can be fit into 1770 2 times, resulting in a remainder of 392.
Put 2 as the next digit of the answer. 
Result so far: 4600.72
Subtracting 1378 from 1770 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 10:
When dividing 3920 by 689, we get 5 with a remainder of 475.
Put 5 as the next digit of the answer. 
Result so far: 4600.725
Subtract 3445 from 3920 to get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 11:
689 can be fit into 4750 6 times, resulting in a remainder of 616.
The next digit of our result is 6. 
Result so far: 4600.7256
If we subtract 4134 from 4750, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 12:
689 can be fit into 6160 8 times, resulting in a remainder of 648.
Write down 8 as next digit of the result. 
Result so far: 4600.72568
The remainder is 648 after subtracting 5512 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 13:
689 goes into 6480 9 times with a remainder of 279.
Write down 9 as next digit of the result. 
Result so far: 4600.725689
Subtracting 6201 from 6480 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 14:
689 goes into 2790 4 times with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 4600.7256894
Deduct 2756 from 2790 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 15:
689 goes into 340 0 times with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 4600.7256894
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

After the division, we end up with 4600.7256894 and a remainder of 3.4e-07.
