Let's divide 30986669 by 42
Let's see how many times 42 fits into 30986669.

Moving on to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 42

Step 2:
The number 42 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 42

Moving on to step 3:
42 can be fit into 309 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 294 from 309 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 42

Advancing to step 4:
42 goes into 158 3 times with a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
The remainder is 32 after subtracting 126 from 158.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 42

Going ahead to step 5:
When dividing 326 by 42, we get 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 737.0
Subtracting 294 from 326 leaves us with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 42

Step 6:
42 goes into 326 7 times with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 7377.0
Subtracting 294 from 326 leaves us with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 42

Advancing to step 7:
The number 42 fits into 326 7 times, leaving a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 73777.0
Subtract 294 from 326 to get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 42

On to step 8:
42 goes into 329 7 times with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 737777.0
Subtracting 294 from 329 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
350 divided by 42 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 737777.8
Subtracting 336 from 350 leaves us 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.

On to step 10:
42 goes into 140 3 times with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 737777.83
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 42 is 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 737777.833
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 737777.833 with a remaining 0.0014.
