We look at the division of 13503980 by 819 
Our goal is to divide 13503980 by 819.

Moving on to step 1:
819 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 819

Step 2:
819 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 819

Going ahead to step 3:
If we divide 135 by 819, we get 0 and a remainder of 135.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 135, we get 135.
Bring next digit (0) of the dividend behind the 135 and repeat the process: 1350 / 819

On to step 4:
819 can be fit into 1350 1 times, resulting in a remainder of 531.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 819 from 1350 to get 531.
Bring next digit (3) of the dividend behind the 531 and repeat the process: 5313 / 819

On to step 5:
If we divide 5313 by 819, we get 6 and a remainder of 399.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 4914 from 5313 and we're left with 399.
Grab the next digit (9) from the dividend, add it to 399, then carry on: 3999 / 819

Going ahead to step 6:
If we divide 3999 by 819, we get 4 and a remainder of 723.
Use 4 as the next digit of our solution. 
Result so far: 164.0
The remainder is 723 after subtracting 3276 from 3999.
Grab the next digit (8) from the dividend, add it to 723, then carry on: 7238 / 819

Moving on to step 7:
The number 819 fits into 7238 8 times, leaving a remainder of 686.
Write down 8 as next digit of the result. 
Result so far: 1648.0
Deduct 6552 from 7238 and we're left with 686.
Take the next digit (0) from the dividend and append it to 686, then repeat: 6860 / 819

Moving on to step 8:
819 can be fit into 6860 8 times, resulting in a remainder of 308.
Write down 8 as next digit of the result. 
Result so far: 16488.0
If we subtract 6552 from 6860, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 9:
When dividing 3080 by 819, we get 3 with a remainder of 623.
Write down 3 as next digit of the result. 
Result so far: 16488.3
If we take 2457 away from 3080, we end up with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

On to step 10:
The number 819 fits into 6230 7 times, leaving a remainder of 497.
Use 7 as the next digit of our solution. 
Result so far: 16488.37
If we take 5733 away from 6230, we end up with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

On to step 11:
If we divide 4970 by 819, we get 6 and a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 16488.376
Deduct 4914 from 4970 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
If we divide 560 by 819, we get 0 and a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 16488.376
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 13:
The number 819 fits into 5600 6 times, leaving a remainder of 686.
The next digit of our result is 6. 
Result so far: 16488.37606
Subtracting 4914 from 5600 leaves us with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

On to step 14:
The number 819 fits into 6860 8 times, leaving a remainder of 308.
Put 8 as the next digit of the answer. 
Result so far: 16488.376068
If we subtract 6552 from 6860, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 15:
When dividing 3080 by 819, we get 3 with a remainder of 623.
Put 3 as the next digit of the answer. 
Result so far: 16488.3760683
The remainder is 623 after subtracting 2457 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 16:
The number 819 fits into 6230 7 times, leaving a remainder of 497.
Put 7 as the next digit of the answer. 
Result so far: 16488.37606837
If we take 5733 away from 6230, we end up with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

The final result is 16488.37606837 with a remainder of 4.97e-07.
