Let's divide 403215 by 14
We want to divide 403215 by 14.

Moving on to step 1:
14 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 14

Advancing to step 2:
The number 14 fits into 40 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 28 from 40 to get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 14

Advancing to step 3:
The number 14 fits into 123 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 28.0
The remainder is 11 after subtracting 112 from 123.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 14

Step 4:
14 goes into 112 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 288.0
If we take 112 away from 112, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 14

Advancing to step 5:
1 divided by 14 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 2880.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 14

Moving on to step 6:
14 can be fit into 15 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 28801.0
Deduct 14 from 15 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.

Let's proceed to step 7:
14 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 28801.0
If we subtract 0 from 10, we get 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 8:
When dividing 100 by 14, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 28801.07
If we subtract 98 from 100, we get 2.
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 9:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 28801.071
Subtracting 14 from 20 leaves us 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.

Going ahead to step 10:
When dividing 60 by 14, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 28801.0714
If we take 56 away from 60, we end up 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.

Let's proceed to step 11:
40 divided by 14 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 28801.07142
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
If we divide 120 by 14, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 28801.071428
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
If we divide 80 by 14, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 28801.0714285
Subtract 70 from 80 to get 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 14:
When dividing 100 by 14, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 28801.07142857
If we subtract 98 from 100, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 28801.07142857 with a remainder of 2e-09.
