We look at the division of 13110399 by 812 
Let's see how many times 812 fits into 13110399.

Advancing to step 1:
If we divide 1 by 812, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 812

Moving on to step 2:
If we divide 13 by 812, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 812

On to step 3:
The number 812 fits into 131 0 times, leaving a remainder of 131.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 131 and we're left with 131.
Grab the next digit (1) from the dividend, add it to 131, then carry on: 1311 / 812

Going ahead to step 4:
The number 812 fits into 1311 1 times, leaving a remainder of 499.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 812 from 1311 to get 499.
Bring next digit (0) of the dividend behind the 499 and repeat the process: 4990 / 812

Advancing to step 5:
4990 divided by 812 is 6 with a remainder of 118.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 4872 away from 4990, we end up with 118.
Fetch the next digit (3) from the dividend, attach it to 118 and continue: 1183 / 812

Moving on to step 6:
If we divide 1183 by 812, we get 1 and a remainder of 371.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Subtract 812 from 1183 to get 371.
Grab the next digit (9) from the dividend, add it to 371, then carry on: 3719 / 812

Let's proceed to step 7:
812 goes into 3719 4 times with a remainder of 471.
Use 4 as the next digit of our solution. 
Result so far: 1614.0
Subtracting 3248 from 3719 leaves us with 471.
Grab the next digit (9) from the dividend, add it to 471, then carry on: 4719 / 812

Moving on to step 8:
4719 divided by 812 is 5 with a remainder of 659.
The number 5 becomes the next digit in our result. 
Result so far: 16145.0
Subtracting 4060 from 4719 leaves us with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Advancing to step 9:
812 can be fit into 6590 8 times, resulting in a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 16145.8
The remainder is 94 after subtracting 6496 from 6590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 10:
The number 812 fits into 940 1 times, leaving a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 16145.81
Subtract 812 from 940 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 11:
812 goes into 1280 1 times with a remainder of 468.
The number 1 becomes the next digit in our result. 
Result so far: 16145.811
Subtracting 812 from 1280 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

In conclusion, the division gives 16145.811 with a balance of 0.0468.
