We look at the division of 81409190 by 635 
We're looking to find how many times 635 goes into 81409190.

On to step 1:
The number 635 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 635

Moving on to step 2:
If we divide 81 by 635, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (4) from the dividend to 81 and continue with: 814 / 635

On to step 3:
635 can be fit into 814 1 times, resulting in a remainder of 179.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 179 after subtracting 635 from 814.
Append the next digit (0) from the dividend to 179 and continue with: 1790 / 635

Moving on to step 4:
635 can be fit into 1790 2 times, resulting in a remainder of 520.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 1270 from 1790 to get 520.
Bring next digit (9) of the dividend behind the 520 and repeat the process: 5209 / 635

Going ahead to step 5:
635 goes into 5209 8 times with a remainder of 129.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtracting 5080 from 5209 leaves us with 129.
Include the next digit (1) from the dividend after 129, then repeat: 1291 / 635

Moving on to step 6:
635 can be fit into 1291 2 times, resulting in a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 1282.0
Subtract 1270 from 1291 to get 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 635

Step 7:
635 can be fit into 219 0 times, resulting in a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 12820.0
If we take 0 away from 219, we end up with 219.
Take the next digit (0) from the dividend and append it to 219, then repeat: 2190 / 635

Step 8:
635 can be fit into 2190 3 times, resulting in a remainder of 285.
The number 3 becomes the next digit in our result. 
Result so far: 128203.0
Subtract 1905 from 2190 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 9:
635 goes into 2850 4 times with a remainder of 310.
Use 4 as the next digit of our solution. 
Result so far: 128203.4
The remainder is 310 after subtracting 2540 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 10:
If we divide 3100 by 635, we get 4 and a remainder of 560.
Use 4 as the next digit of our solution. 
Result so far: 128203.44
Deduct 2540 from 3100 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.

After the division, we end up with 128203.44 and a remainder of 0.56.
