We look at the division of 81420486 by 419 
We want to divide 81420486 by 419.

Going ahead to step 1:
8 divided by 419 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 419

Advancing to step 2:
The number 419 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 419

On to step 3:
419 goes into 814 1 times with a remainder of 395.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 395 after subtracting 419 from 814.
Append the next digit (2) from the dividend to 395 and continue with: 3952 / 419

Step 4:
The number 419 fits into 3952 9 times, leaving a remainder of 181.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 3771 from 3952 to get 181.
Append the next digit (0) from the dividend to 181 and continue with: 1810 / 419

Moving on to step 5:
If we divide 1810 by 419, we get 4 and a remainder of 134.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
The remainder is 134 after subtracting 1676 from 1810.
Append the next digit (4) from the dividend to 134 and continue with: 1344 / 419

Step 6:
1344 divided by 419 is 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 1943.0
If we take 1257 away from 1344, we end up with 87.
Include the next digit (8) from the dividend after 87, then repeat: 878 / 419

Let's proceed to step 7:
If we divide 878 by 419, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 19432.0
The remainder is 40 after subtracting 838 from 878.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 419

Let's proceed to step 8:
The number 419 fits into 406 0 times, leaving a remainder of 406.
The next digit of our result is 0. 
Result so far: 194320.0
Subtracting 0 from 406 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 9:
419 can be fit into 4060 9 times, resulting in a remainder of 289.
Record the quotient 9 as the next digit in the result. 
Result so far: 194320.9
Subtract 3771 from 4060 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 10:
419 goes into 2890 6 times with a remainder of 376.
Use 6 as the next digit of our solution. 
Result so far: 194320.96
If we take 2514 away from 2890, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 11:
If we divide 3760 by 419, we get 8 and a remainder of 408.
Use 8 as the next digit of our solution. 
Result so far: 194320.968
Deduct 3352 from 3760 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 12:
419 can be fit into 4080 9 times, resulting in a remainder of 309.
Record the quotient 9 as the next digit in the result. 
Result so far: 194320.9689
The remainder is 309 after subtracting 3771 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 13:
The number 419 fits into 3090 7 times, leaving a remainder of 157.
The number 7 becomes the next digit in our result. 
Result so far: 194320.96897
Deduct 2933 from 3090 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 14:
If we divide 1570 by 419, we get 3 and a remainder of 313.
The next digit of our result is 3. 
Result so far: 194320.968973
If we take 1257 away from 1570, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Let's proceed to step 15:
3130 divided by 419 is 7 with a remainder of 197.
Put 7 as the next digit of the answer. 
Result so far: 194320.9689737
The remainder is 197 after subtracting 2933 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 16:
If we divide 1970 by 419, we get 4 and a remainder of 294.
Record the quotient 4 as the next digit in the result. 
Result so far: 194320.96897374
Subtracting 1676 from 1970 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

The final result is 194320.96897374 with a remainder of 2.94e-07.
