6218486 divided by 401 
Our goal is to divide 6218486 by 401.

Step 1:
6 divided by 401 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 401

Moving on to step 2:
The number 401 fits into 62 0 times, leaving a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 401

On to step 3:
401 goes into 621 1 times with a remainder of 220.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 401 from 621, we get 220.
Fetch the next digit (8) from the dividend, attach it to 220 and continue: 2208 / 401

On to step 4:
If we divide 2208 by 401, we get 5 and a remainder of 203.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 203 after subtracting 2005 from 2208.
Fetch the next digit (4) from the dividend, attach it to 203 and continue: 2034 / 401

Moving on to step 5:
2034 divided by 401 is 5 with a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 155.0
If we subtract 2005 from 2034, we get 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 401

Step 6:
When dividing 298 by 401, we get 0 with a remainder of 298.
Put 0 as the next digit of the answer. 
Result so far: 1550.0
If we take 0 away from 298, we end up with 298.
Bring next digit (6) of the dividend behind the 298 and repeat the process: 2986 / 401

Let's proceed to step 7:
2986 divided by 401 is 7 with a remainder of 179.
The number 7 becomes the next digit in our result. 
Result so far: 15507.0
If we subtract 2807 from 2986, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 8:
401 goes into 1790 4 times with a remainder of 186.
The next digit of our result is 4. 
Result so far: 15507.4
The remainder is 186 after subtracting 1604 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 9:
The number 401 fits into 1860 4 times, leaving a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 15507.44
Subtract 1604 from 1860 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final result is 15507.44 with a remainder of 0.256.
