We look at the division of 646396 by 46 
We want to figure out the number of times 646396 can be divided by 46.

Advancing to step 1:
When dividing 6 by 46, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 46

Moving on to step 2:
64 divided by 46 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 46 away from 64, we end up with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 46

On to step 3:
186 divided by 46 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 184 from 186, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 46

Advancing to step 4:
The number 46 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
The remainder is 23 after subtracting 0 from 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 46

Moving on to step 5:
If we divide 239 by 46, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 1405.0
If we take 230 away from 239, we end up with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 46

Moving on to step 6:
If we divide 96 by 46, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 14052.0
Subtracting 92 from 96 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.

Advancing to step 7:
When dividing 40 by 46, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 14052.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
46 goes into 400 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 14052.08
Deduct 368 from 400 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
If we divide 320 by 46, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 14052.086
If we take 276 away from 320, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
46 can be fit into 440 9 times, resulting in a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 14052.0869
If we take 414 away from 440, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
The number 46 fits into 260 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 14052.08695
If we subtract 230 from 260, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
The number 46 fits into 300 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 14052.086956
Deduct 276 from 300 and we're left 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.

On to step 13:
When dividing 240 by 46, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 14052.0869565
If we take 230 away from 240, we end up 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.

Moving on to step 14:
46 goes into 100 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 14052.08695652
Deduct 92 from 100 and we're left 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.

The final result is 14052.08695652 with a remainder of 8e-09.
