We're dividing 646452 by 46 
We want to divide 646452 by 46.

Going ahead to step 1:
46 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 46

Going ahead to step 2:
46 can be fit into 64 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 46 from 64 and we're left with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 46

Let's proceed to step 3:
If we divide 186 by 46, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 184 from 186 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 46

On to step 4:
24 divided by 46 is 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtract 0 from 24 to get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 46

Let's proceed to step 5:
If we divide 245 by 46, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1405.0
The remainder is 15 after subtracting 230 from 245.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 46

Let's proceed to step 6:
The number 46 fits into 152 3 times, leaving a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 14053.0
The remainder is 14 after subtracting 138 from 152.
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 7:
The number 46 fits into 140 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 14053.3
Deduct 138 from 140 and we're left with 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 8:
46 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 14053.3
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 46, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 14053.304
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
160 divided by 46 is 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 14053.3043
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
When dividing 220 by 46, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 14053.30434
Deduct 184 from 220 and we're left 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.

Going ahead to step 12:
360 divided by 46 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 14053.304347
Deduct 322 from 360 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
46 goes into 380 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 14053.3043478
Subtract 368 from 380 to 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.

Let's proceed to step 14:
46 can be fit into 120 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 14053.30434782
Subtracting 92 from 120 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 14053.30434782 and a remainder of 2.8e-08.
