We're dividing 30394342 by 689 
We want to divide 30394342 by 689.

Step 1:
3 divided by 689 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 689

Step 2:
The number 689 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 689

Let's proceed to step 3:
If we divide 303 by 689, we get 0 and a remainder of 303.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 303 to get 303.
Append the next digit (9) from the dividend to 303 and continue with: 3039 / 689

Advancing to step 4:
If we divide 3039 by 689, we get 4 and a remainder of 283.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2756 from 3039 to get 283.
Append the next digit (4) from the dividend to 283 and continue with: 2834 / 689

Advancing to step 5:
When dividing 2834 by 689, we get 4 with a remainder of 78.
The next digit of our result is 4. 
Result so far: 44.0
The remainder is 78 after subtracting 2756 from 2834.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 689

Let's proceed to step 6:
The number 689 fits into 783 1 times, leaving a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 441.0
Deduct 689 from 783 and we're left with 94.
Fetch the next digit (4) from the dividend, attach it to 94 and continue: 944 / 689

Advancing to step 7:
689 goes into 944 1 times with a remainder of 255.
Record the quotient 1 as the next digit in the result. 
Result so far: 4411.0
The remainder is 255 after subtracting 689 from 944.
Bring next digit (2) of the dividend behind the 255 and repeat the process: 2552 / 689

On to step 8:
When dividing 2552 by 689, we get 3 with a remainder of 485.
Record the quotient 3 as the next digit in the result. 
Result so far: 44113.0
Subtract 2067 from 2552 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 9:
The number 689 fits into 4850 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 44113.7
Deduct 4823 from 4850 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
689 can be fit into 270 0 times, resulting in a remainder of 270.
The next digit of our result is 0. 
Result so far: 44113.7
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
2700 divided by 689 is 3 with a remainder of 633.
Write down 3 as next digit of the result. 
Result so far: 44113.703
Subtracting 2067 from 2700 leaves us with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Moving on to step 12:
If we divide 6330 by 689, we get 9 and a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 44113.7039
The remainder is 129 after subtracting 6201 from 6330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 13:
The number 689 fits into 1290 1 times, leaving a remainder of 601.
Record the quotient 1 as the next digit in the result. 
Result so far: 44113.70391
Subtract 689 from 1290 to get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Step 14:
689 goes into 6010 8 times with a remainder of 498.
Write down 8 as next digit of the result. 
Result so far: 44113.703918
Deduct 5512 from 6010 and we're left 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.

Advancing to step 15:
When dividing 4980 by 689, we get 7 with a remainder of 157.
Record the quotient 7 as the next digit in the result. 
Result so far: 44113.7039187
Subtracting 4823 from 4980 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 16:
689 goes into 1570 2 times with a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 44113.70391872
Subtracting 1378 from 1570 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The quotient of the division is 44113.70391872, and the remainder is 1.92e-07.
