We look at the division of 646140 by 14 
We want to divide 646140 by 14.

On to step 1:
The number 14 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 14

Step 2:
14 goes into 64 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 56 from 64 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 14

On to step 3:
14 goes into 86 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Deduct 84 from 86 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 14

Moving on to step 4:
The number 14 fits into 21 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 461.0
Subtract 14 from 21 to get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 14

Let's proceed to step 5:
14 can be fit into 74 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 4615.0
Deduct 70 from 74 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 14

Advancing to step 6:
If we divide 40 by 14, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 46152.0
If we take 28 away from 40, 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.

Advancing to step 7:
The number 14 fits into 120 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 46152.8
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
80 divided by 14 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 46152.85
Subtracting 70 from 80 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 14, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 46152.857
The remainder is 2 after subtracting 98 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 46152.8571
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 11:
When dividing 60 by 14, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 46152.85714
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
14 goes into 40 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 46152.857142
Subtracting 28 from 40 leaves us 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 13:
If we divide 120 by 14, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 46152.8571428
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
The number 14 fits into 80 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 46152.85714285
The remainder is 10 after subtracting 70 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 46152.85714285 with a balance of 1e-08.
