Let's divide 28570635 by 393
We want to divide 28570635 by 393.

Step 1:
The number 393 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 393

Let's proceed to step 2:
The number 393 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 393

Moving on to step 3:
When dividing 285 by 393, we get 0 with a remainder of 285.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 285, we get 285.
Include the next digit (7) from the dividend after 285, then repeat: 2857 / 393

On to step 4:
393 goes into 2857 7 times with a remainder of 106.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 2751 from 2857 and we're left with 106.
Bring next digit (0) of the dividend behind the 106 and repeat the process: 1060 / 393

Let's proceed to step 5:
The number 393 fits into 1060 2 times, leaving a remainder of 274.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtract 786 from 1060 to get 274.
Bring next digit (6) of the dividend behind the 274 and repeat the process: 2746 / 393

On to step 6:
393 can be fit into 2746 6 times, resulting in a remainder of 388.
The number 6 becomes the next digit in our result. 
Result so far: 726.0
If we take 2358 away from 2746, we end up with 388.
Grab the next digit (3) from the dividend, add it to 388, then carry on: 3883 / 393

On to step 7:
The number 393 fits into 3883 9 times, leaving a remainder of 346.
The next digit of our result is 9. 
Result so far: 7269.0
If we subtract 3537 from 3883, we get 346.
Grab the next digit (5) from the dividend, add it to 346, then carry on: 3465 / 393

Let's proceed to step 8:
393 goes into 3465 8 times with a remainder of 321.
Put 8 as the next digit of the answer. 
Result so far: 72698.0
If we subtract 3144 from 3465, we get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 9:
393 can be fit into 3210 8 times, resulting in a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 72698.8
If we take 3144 away from 3210, we end up with 66.
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 10:
When dividing 660 by 393, we get 1 with a remainder of 267.
Put 1 as the next digit of the answer. 
Result so far: 72698.81
If we take 393 away from 660, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 11:
2670 divided by 393 is 6 with a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 72698.816
Subtract 2358 from 2670 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 12:
When dividing 3120 by 393, we get 7 with a remainder of 369.
The next digit of our result is 7. 
Result so far: 72698.8167
The remainder is 369 after subtracting 2751 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 13:
393 goes into 3690 9 times with a remainder of 153.
The next digit of our result is 9. 
Result so far: 72698.81679
Subtracting 3537 from 3690 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 14:
The number 393 fits into 1530 3 times, leaving a remainder of 351.
The next digit of our result is 3. 
Result so far: 72698.816793
Deduct 1179 from 1530 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 15:
3510 divided by 393 is 8 with a remainder of 366.
Put 8 as the next digit of the answer. 
Result so far: 72698.8167938
If we take 3144 away from 3510, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 16:
When dividing 3660 by 393, we get 9 with a remainder of 123.
Put 9 as the next digit of the answer. 
Result so far: 72698.81679389
If we subtract 3537 from 3660, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The quotient of the division is 72698.81679389, and the remainder is 1.23e-07.
