396399 ÷ 93 
Our goal is to divide 396399 by 93.

Advancing to step 1:
93 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 93

Advancing to step 2:
If we divide 39 by 93, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 93

On to step 3:
The number 93 fits into 396 4 times, leaving a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 372 from 396 leaves us with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 93

Advancing to step 4:
93 goes into 243 2 times with a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 186 from 243 and we're left with 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 93

Step 5:
93 goes into 579 6 times with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 426.0
Deduct 558 from 579 and we're left with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 93

On to step 6:
The number 93 fits into 219 2 times, leaving a remainder of 33.
The next digit of our result is 2. 
Result so far: 4262.0
If we subtract 186 from 219, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
330 divided by 93 is 3 with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 4262.3
If we take 279 away from 330, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 8:
93 can be fit into 510 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 4262.35
If we subtract 465 from 510, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
450 divided by 93 is 4 with a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 4262.354
The remainder is 78 after subtracting 372 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 10:
The number 93 fits into 780 8 times, leaving a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 4262.3548
Subtract 744 from 780 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
If we divide 360 by 93, we get 3 and a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 4262.35483
The remainder is 81 after subtracting 279 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 12:
810 divided by 93 is 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 4262.354838
The remainder is 66 after subtracting 744 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
When dividing 660 by 93, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 4262.3548387
Deduct 651 from 660 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
93 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 4262.3548387
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 4262.3548387, with a leftover of 9e-08.
