We divide 306990 by 42
Let's see how many times 42 fits into 306990.

Advancing to step 1:
3 divided by 42 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 42

On to step 2:
If we divide 30 by 42, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 42

Step 3:
When dividing 306 by 42, we get 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 294 from 306 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 42

Going ahead to step 4:
When dividing 129 by 42, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtract 126 from 129 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 42

Advancing to step 5:
If we divide 39 by 42, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 730.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 42

Advancing to step 6:
The number 42 fits into 390 9 times, leaving a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 7309.0
If we take 378 away from 390, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 7309.2
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
When dividing 360 by 42, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 7309.28
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
42 goes into 240 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 7309.285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 42, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7309.2857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
When dividing 60 by 42, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 7309.28571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
180 divided by 42 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 7309.285714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 7309.2857142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
If we divide 360 by 42, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 7309.28571428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 7309.28571428 and a remainder of 2.4e-08.
