Let's divide 306148 by 7
We want to divide 306148 by 7.

Going ahead to step 1:
7 goes into 3 0 times 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.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 7

On to step 2:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 28 from 30 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 7

Step 3:
7 goes into 26 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 21 from 26 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 7

On to step 4:
7 goes into 51 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 437.0
If we subtract 49 from 51, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 7

Going ahead to step 5:
7 goes into 24 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 4373.0
Deduct 21 from 24 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 7

Step 6:
The number 7 fits into 38 5 times, leaving a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 43735.0
If we subtract 35 from 38, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 43735.4
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 7, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 43735.42
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 43735.428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 43735.4285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 43735.42857
Deduct 49 from 50 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 43735.428571
Deduct 7 from 10 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 43735.4285714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 43735.42857142
If we subtract 14 from 20, we 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.

In conclusion, the division gives 43735.42857142 with a balance of 6e-09.
