Let's divide 31328729 by 817
We're looking to find how many times 817 goes into 31328729.

Moving on to step 1:
If we divide 3 by 817, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 817

Let's proceed to step 2:
The number 817 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 817

Let's proceed to step 3:
The number 817 fits into 313 0 times, leaving a remainder of 313.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 313 to get 313.
Grab the next digit (2) from the dividend, add it to 313, then carry on: 3132 / 817

On to step 4:
If we divide 3132 by 817, we get 3 and a remainder of 681.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2451 from 3132 and we're left with 681.
Grab the next digit (8) from the dividend, add it to 681, then carry on: 6818 / 817

On to step 5:
817 goes into 6818 8 times with a remainder of 282.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtract 6536 from 6818 to get 282.
Append the next digit (7) from the dividend to 282 and continue with: 2827 / 817

Going ahead to step 6:
817 can be fit into 2827 3 times, resulting in a remainder of 376.
Record the quotient 3 as the next digit in the result. 
Result so far: 383.0
The remainder is 376 after subtracting 2451 from 2827.
Grab the next digit (2) from the dividend, add it to 376, then carry on: 3762 / 817

Advancing to step 7:
If we divide 3762 by 817, we get 4 and a remainder of 494.
The next digit of our result is 4. 
Result so far: 3834.0
If we subtract 3268 from 3762, we get 494.
Append the next digit (9) from the dividend to 494 and continue with: 4949 / 817

Moving on to step 8:
When dividing 4949 by 817, we get 6 with a remainder of 47.
The next digit of our result is 6. 
Result so far: 38346.0
The remainder is 47 after subtracting 4902 from 4949.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
The number 817 fits into 470 0 times, leaving a remainder of 470.
Use 0 as the next digit of our solution. 
Result so far: 38346.0
If we subtract 0 from 470, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 10:
If we divide 4700 by 817, we get 5 and a remainder of 615.
The next digit of our result is 5. 
Result so far: 38346.05
If we take 4085 away from 4700, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

On to step 11:
817 can be fit into 6150 7 times, resulting in a remainder of 431.
Write down 7 as next digit of the result. 
Result so far: 38346.057
Subtracting 5719 from 6150 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Step 12:
If we divide 4310 by 817, we get 5 and a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 38346.0575
Deduct 4085 from 4310 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 13:
817 can be fit into 2250 2 times, resulting in a remainder of 616.
Write down 2 as next digit of the result. 
Result so far: 38346.05752
The remainder is 616 after subtracting 1634 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Advancing to step 14:
817 goes into 6160 7 times with a remainder of 441.
Record the quotient 7 as the next digit in the result. 
Result so far: 38346.057527
Subtracting 5719 from 6160 leaves us with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Going ahead to step 15:
If we divide 4410 by 817, we get 5 and a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 38346.0575275
The remainder is 325 after subtracting 4085 from 4410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 16:
When dividing 3250 by 817, we get 3 with a remainder of 799.
Write down 3 as next digit of the result. 
Result so far: 38346.05752753
Deduct 2451 from 3250 and we're left with 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

The final result is 38346.05752753 with a remainder of 7.99e-07.
