We look at the division of 20076456 by 401 
We want to divide 20076456 by 401.

Advancing to step 1:
When dividing 2 by 401, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 401

Advancing to step 2:
401 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 401

Advancing to step 3:
When dividing 200 by 401, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 200 to get 200.
Grab the next digit (7) from the dividend, add it to 200, then carry on: 2007 / 401

On to step 4:
401 can be fit into 2007 5 times, resulting in a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 2005 from 2007 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 401

Going ahead to step 5:
401 can be fit into 26 0 times, resulting in a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 26, we get 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 401

On to step 6:
264 divided by 401 is 0 with a remainder of 264.
Use 0 as the next digit of our solution. 
Result so far: 500.0
Subtract 0 from 264 to get 264.
Bring next digit (5) of the dividend behind the 264 and repeat the process: 2645 / 401

On to step 7:
2645 divided by 401 is 6 with a remainder of 239.
The number 6 becomes the next digit in our result. 
Result so far: 5006.0
If we subtract 2406 from 2645, we get 239.
Grab the next digit (6) from the dividend, add it to 239, then carry on: 2396 / 401

Step 8:
The number 401 fits into 2396 5 times, leaving a remainder of 391.
Put 5 as the next digit of the answer. 
Result so far: 50065.0
Subtracting 2005 from 2396 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 9:
When dividing 3910 by 401, we get 9 with a remainder of 301.
The next digit of our result is 9. 
Result so far: 50065.9
The remainder is 301 after subtracting 3609 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 10:
401 goes into 3010 7 times with a remainder of 203.
The next digit of our result is 7. 
Result so far: 50065.97
Deduct 2807 from 3010 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 11:
The number 401 fits into 2030 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 50065.975
If we subtract 2005 from 2030, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
250 divided by 401 is 0 with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 50065.975
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 13:
401 goes into 2500 6 times with a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 50065.97506
Subtract 2406 from 2500 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 14:
When dividing 940 by 401, we get 2 with a remainder of 138.
Use 2 as the next digit of our solution. 
Result so far: 50065.975062
The remainder is 138 after subtracting 802 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 15:
1380 divided by 401 is 3 with a remainder of 177.
The number 3 becomes the next digit in our result. 
Result so far: 50065.9750623
Subtracting 1203 from 1380 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 16:
When dividing 1770 by 401, we get 4 with a remainder of 166.
Put 4 as the next digit of the answer. 
Result so far: 50065.97506234
The remainder is 166 after subtracting 1604 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final result is 50065.97506234 with a remainder of 1.66e-07.
