We're dividing 13726438 by 810 
We're looking to find how many times 810 goes into 13726438.

Moving on to step 1:
810 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 810

Moving on to step 2:
The number 810 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 810

On to step 3:
When dividing 137 by 810, we get 0 with a remainder of 137.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 137, we end up with 137.
Grab the next digit (2) from the dividend, add it to 137, then carry on: 1372 / 810

Advancing to step 4:
When dividing 1372 by 810, we get 1 with a remainder of 562.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 562 after subtracting 810 from 1372.
Take the next digit (6) from the dividend and append it to 562, then repeat: 5626 / 810

On to step 5:
When dividing 5626 by 810, we get 6 with a remainder of 766.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 4860 from 5626 to get 766.
Take the next digit (4) from the dividend and append it to 766, then repeat: 7664 / 810

Let's proceed to step 6:
7664 divided by 810 is 9 with a remainder of 374.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Subtract 7290 from 7664 to get 374.
Grab the next digit (3) from the dividend, add it to 374, then carry on: 3743 / 810

Going ahead to step 7:
3743 divided by 810 is 4 with a remainder of 503.
Use 4 as the next digit of our solution. 
Result so far: 1694.0
The remainder is 503 after subtracting 3240 from 3743.
Take the next digit (8) from the dividend and append it to 503, then repeat: 5038 / 810

Step 8:
810 can be fit into 5038 6 times, resulting in a remainder of 178.
The number 6 becomes the next digit in our result. 
Result so far: 16946.0
If we take 4860 away from 5038, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 9:
If we divide 1780 by 810, we get 2 and a remainder of 160.
The next digit of our result is 2. 
Result so far: 16946.2
Subtracting 1620 from 1780 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
If we divide 1600 by 810, we get 1 and a remainder of 790.
Write down 1 as next digit of the result. 
Result so far: 16946.21
The remainder is 790 after subtracting 810 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 11:
810 goes into 7900 9 times with a remainder of 610.
Write down 9 as next digit of the result. 
Result so far: 16946.219
If we subtract 7290 from 7900, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 12:
When dividing 6100 by 810, we get 7 with a remainder of 430.
Record the quotient 7 as the next digit in the result. 
Result so far: 16946.2197
The remainder is 430 after subtracting 5670 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 13:
810 can be fit into 4300 5 times, resulting in a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 16946.21975
If we take 4050 away from 4300, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
810 can be fit into 2500 3 times, resulting in a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 16946.219753
If we take 2430 away from 2500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 15:
810 can be fit into 700 0 times, resulting in a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 16946.219753
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 16:
When dividing 7000 by 810, we get 8 with a remainder of 520.
Put 8 as the next digit of the answer. 
Result so far: 16946.21975308
The remainder is 520 after subtracting 6480 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final result is 16946.21975308 with a remainder of 5.2e-07.
