Let's divide 31309499 by 819
We're looking to find how many times 819 goes into 31309499.

On to step 1:
3 divided by 819 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
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 / 819

Moving on to step 2:
819 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 819

On to step 3:
819 goes into 313 0 times with a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 313 to get 313.
Take the next digit (0) from the dividend and append it to 313, then repeat: 3130 / 819

Step 4:
3130 divided by 819 is 3 with a remainder of 673.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2457 from 3130 to get 673.
Fetch the next digit (9) from the dividend, attach it to 673 and continue: 6739 / 819

Step 5:
The number 819 fits into 6739 8 times, leaving a remainder of 187.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we take 6552 away from 6739, we end up with 187.
Fetch the next digit (4) from the dividend, attach it to 187 and continue: 1874 / 819

On to step 6:
When dividing 1874 by 819, we get 2 with a remainder of 236.
The next digit of our result is 2. 
Result so far: 382.0
If we take 1638 away from 1874, we end up with 236.
Append the next digit (9) from the dividend to 236 and continue with: 2369 / 819

Let's proceed to step 7:
If we divide 2369 by 819, we get 2 and a remainder of 731.
Record the quotient 2 as the next digit in the result. 
Result so far: 3822.0
Subtracting 1638 from 2369 leaves us with 731.
Grab the next digit (9) from the dividend, add it to 731, then carry on: 7319 / 819

Advancing to step 8:
If we divide 7319 by 819, we get 8 and a remainder of 767.
Record the quotient 8 as the next digit in the result. 
Result so far: 38228.0
If we subtract 6552 from 7319, we get 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Advancing to step 9:
The number 819 fits into 7670 9 times, leaving a remainder of 299.
Put 9 as the next digit of the answer. 
Result so far: 38228.9
If we take 7371 away from 7670, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Step 10:
819 can be fit into 2990 3 times, resulting in a remainder of 533.
The next digit of our result is 3. 
Result so far: 38228.93
Subtract 2457 from 2990 to get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Let's proceed to step 11:
When dividing 5330 by 819, we get 6 with a remainder of 416.
Record the quotient 6 as the next digit in the result. 
Result so far: 38228.936
The remainder is 416 after subtracting 4914 from 5330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 12:
819 can be fit into 4160 5 times, resulting in a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 38228.9365
If we take 4095 away from 4160, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 13:
When dividing 650 by 819, we get 0 with a remainder of 650.
The number 0 becomes the next digit in our result. 
Result so far: 38228.9365
The remainder is 650 after subtracting 0 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 14:
819 can be fit into 6500 7 times, resulting in a remainder of 767.
Put 7 as the next digit of the answer. 
Result so far: 38228.936507
If we subtract 5733 from 6500, we get 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Step 15:
The number 819 fits into 7670 9 times, leaving a remainder of 299.
The next digit of our result is 9. 
Result so far: 38228.9365079
Subtract 7371 from 7670 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 16:
When dividing 2990 by 819, we get 3 with a remainder of 533.
Use 3 as the next digit of our solution. 
Result so far: 38228.93650793
Deduct 2457 from 2990 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

The final outcome is 38228.93650793, with a leftover of 5.33e-07.
