399836 divided by 46 
We want to divide 399836 by 46.

Going ahead to step 1:
46 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 46

On to step 2:
46 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 46

Going ahead to step 3:
The number 46 fits into 399 8 times, leaving a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 368 from 399 and we're left with 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 46

On to step 4:
46 can be fit into 318 6 times, resulting in a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Deduct 276 from 318 and we're left with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 46

On to step 5:
The number 46 fits into 423 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 869.0
Subtracting 414 from 423 leaves us with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 46

Going ahead to step 6:
96 divided by 46 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 8692.0
If we subtract 92 from 96, we get 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 7:
46 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8692.0
Subtract 0 from 40 to 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 next digit of our result is 8. 
Result so far: 8692.08
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.

Advancing to step 9:
If we divide 320 by 46, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 8692.086
Deduct 276 from 320 and we're left 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.

Advancing to step 10:
46 goes into 440 9 times with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 8692.0869
The remainder is 26 after subtracting 414 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
46 can be fit into 260 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8692.08695
Subtracting 230 from 260 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
46 can be fit into 300 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 8692.086956
If we take 276 away from 300, we end up 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.

Going ahead to step 13:
The number 46 fits into 240 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 8692.0869565
If we subtract 230 from 240, 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.

Let's proceed to step 14:
The number 46 fits into 100 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 8692.08695652
If we subtract 92 from 100, 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.

After the division, we end up with 8692.08695652 and a remainder of 8e-09.
