We look at the division of 12804835 by 617 
Let's see how many times 617 fits into 12804835.

Step 1:
The number 617 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 617

Let's proceed to step 2:
When dividing 12 by 617, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 617

Step 3:
617 goes into 128 0 times with a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 128 after subtracting 0 from 128.
Take the next digit (0) from the dividend and append it to 128, then repeat: 1280 / 617

Step 4:
1280 divided by 617 is 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1234 from 1280 and we're left with 46.
Fetch the next digit (4) from the dividend, attach it to 46 and continue: 464 / 617

Let's proceed to step 5:
617 can be fit into 464 0 times, resulting in a remainder of 464.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 464 and we're left with 464.
Fetch the next digit (8) from the dividend, attach it to 464 and continue: 4648 / 617

Step 6:
4648 divided by 617 is 7 with a remainder of 329.
Put 7 as the next digit of the answer. 
Result so far: 207.0
Deduct 4319 from 4648 and we're left with 329.
Bring next digit (3) of the dividend behind the 329 and repeat the process: 3293 / 617

Going ahead to step 7:
617 goes into 3293 5 times with a remainder of 208.
The number 5 becomes the next digit in our result. 
Result so far: 2075.0
Subtracting 3085 from 3293 leaves us with 208.
Grab the next digit (5) from the dividend, add it to 208, then carry on: 2085 / 617

Let's proceed to step 8:
617 can be fit into 2085 3 times, resulting in a remainder of 234.
The number 3 becomes the next digit in our result. 
Result so far: 20753.0
If we subtract 1851 from 2085, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 9:
When dividing 2340 by 617, we get 3 with a remainder of 489.
The next digit of our result is 3. 
Result so far: 20753.3
Subtracting 1851 from 2340 leaves us with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Moving on to step 10:
617 can be fit into 4890 7 times, resulting in a remainder of 571.
Use 7 as the next digit of our solution. 
Result so far: 20753.37
The remainder is 571 after subtracting 4319 from 4890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Advancing to step 11:
617 goes into 5710 9 times with a remainder of 157.
The next digit of our result is 9. 
Result so far: 20753.379
Subtract 5553 from 5710 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 12:
1570 divided by 617 is 2 with a remainder of 336.
Put 2 as the next digit of the answer. 
Result so far: 20753.3792
Subtract 1234 from 1570 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 13:
When dividing 3360 by 617, we get 5 with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 20753.37925
Deduct 3085 from 3360 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 14:
The number 617 fits into 2750 4 times, leaving a remainder of 282.
Record the quotient 4 as the next digit in the result. 
Result so far: 20753.379254
If we subtract 2468 from 2750, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 15:
2820 divided by 617 is 4 with a remainder of 352.
Record the quotient 4 as the next digit in the result. 
Result so far: 20753.3792544
Deduct 2468 from 2820 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final result is 20753.3792544 with a remainder of 3.52e-06.
