We divide 12839427 by 689
We want to figure out the number of times 12839427 can be divided by 689.

Moving on to step 1:
689 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 689

Step 2:
689 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 689

Step 3:
689 goes into 128 0 times with a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 128 leaves us with 128.
Fetch the next digit (3) from the dividend, attach it to 128 and continue: 1283 / 689

Let's proceed to step 4:
When dividing 1283 by 689, we get 1 with a remainder of 594.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 594 after subtracting 689 from 1283.
Fetch the next digit (9) from the dividend, attach it to 594 and continue: 5949 / 689

Advancing to step 5:
If we divide 5949 by 689, we get 8 and a remainder of 437.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 5512 from 5949 and we're left with 437.
Grab the next digit (4) from the dividend, add it to 437, then carry on: 4374 / 689

Advancing to step 6:
689 goes into 4374 6 times with a remainder of 240.
The next digit of our result is 6. 
Result so far: 186.0
The remainder is 240 after subtracting 4134 from 4374.
Take the next digit (2) from the dividend and append it to 240, then repeat: 2402 / 689

Let's proceed to step 7:
When dividing 2402 by 689, we get 3 with a remainder of 335.
The next digit of our result is 3. 
Result so far: 1863.0
If we subtract 2067 from 2402, we get 335.
Take the next digit (7) from the dividend and append it to 335, then repeat: 3357 / 689

Moving on to step 8:
3357 divided by 689 is 4 with a remainder of 601.
Record the quotient 4 as the next digit in the result. 
Result so far: 18634.0
Deduct 2756 from 3357 and we're left with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Going ahead to step 9:
689 can be fit into 6010 8 times, resulting in a remainder of 498.
Put 8 as the next digit of the answer. 
Result so far: 18634.8
If we take 5512 away from 6010, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Let's proceed to step 10:
If we divide 4980 by 689, we get 7 and a remainder of 157.
Record the quotient 7 as the next digit in the result. 
Result so far: 18634.87
If we subtract 4823 from 4980, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 11:
689 can be fit into 1570 2 times, resulting in a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 18634.872
Subtract 1378 from 1570 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 12:
If we divide 1920 by 689, we get 2 and a remainder of 542.
Use 2 as the next digit of our solution. 
Result so far: 18634.8722
If we subtract 1378 from 1920, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

The quotient of the division is 18634.8722, and the remainder is 0.00542.
