We look at the division of 81856134 by 409 
We want to figure out the number of times 81856134 can be divided by 409.

Let's proceed to step 1:
If we divide 8 by 409, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 409

Let's proceed to step 2:
The number 409 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 409

Let's proceed to step 3:
When dividing 818 by 409, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 0 after subtracting 818 from 818.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 409

Going ahead to step 4:
When dividing 5 by 409, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 409

Advancing to step 5:
When dividing 56 by 409, we get 0 with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
Deduct 0 from 56 and we're left with 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 409

Going ahead to step 6:
If we divide 561 by 409, we get 1 and a remainder of 152.
The number 1 becomes the next digit in our result. 
Result so far: 2001.0
If we take 409 away from 561, we end up with 152.
Grab the next digit (3) from the dividend, add it to 152, then carry on: 1523 / 409

Let's proceed to step 7:
409 goes into 1523 3 times with a remainder of 296.
Record the quotient 3 as the next digit in the result. 
Result so far: 20013.0
If we subtract 1227 from 1523, we get 296.
Append the next digit (4) from the dividend to 296 and continue with: 2964 / 409

Let's proceed to step 8:
When dividing 2964 by 409, we get 7 with a remainder of 101.
Record the quotient 7 as the next digit in the result. 
Result so far: 200137.0
If we take 2863 away from 2964, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 9:
409 goes into 1010 2 times with a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 200137.2
The remainder is 192 after subtracting 818 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 10:
The number 409 fits into 1920 4 times, leaving a remainder of 284.
Use 4 as the next digit of our solution. 
Result so far: 200137.24
Subtract 1636 from 1920 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
409 can be fit into 2840 6 times, resulting in a remainder of 386.
Put 6 as the next digit of the answer. 
Result so far: 200137.246
Deduct 2454 from 2840 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 12:
If we divide 3860 by 409, we get 9 and a remainder of 179.
The number 9 becomes the next digit in our result. 
Result so far: 200137.2469
The remainder is 179 after subtracting 3681 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 13:
409 goes into 1790 4 times with a remainder of 154.
The number 4 becomes the next digit in our result. 
Result so far: 200137.24694
Deduct 1636 from 1790 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 14:
The number 409 fits into 1540 3 times, leaving a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 200137.246943
The remainder is 313 after subtracting 1227 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 15:
If we divide 3130 by 409, we get 7 and a remainder of 267.
The next digit of our result is 7. 
Result so far: 200137.2469437
The remainder is 267 after subtracting 2863 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 16:
2670 divided by 409 is 6 with a remainder of 216.
Use 6 as the next digit of our solution. 
Result so far: 200137.24694376
Subtract 2454 from 2670 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The quotient of the division is 200137.24694376, and the remainder is 2.16e-07.
