Let's divide 56878866 by 401
We're looking to find how many times 401 goes into 56878866.

Let's proceed to step 1:
5 divided by 401 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 401

Going ahead to step 2:
When dividing 56 by 401, we get 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 401

On to step 3:
401 goes into 568 1 times with a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 401 from 568 to get 167.
Take the next digit (7) from the dividend and append it to 167, then repeat: 1677 / 401

Step 4:
1677 divided by 401 is 4 with a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 73 after subtracting 1604 from 1677.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 401

Let's proceed to step 5:
If we divide 738 by 401, we get 1 and a remainder of 337.
Put 1 as the next digit of the answer. 
Result so far: 141.0
If we subtract 401 from 738, we get 337.
Grab the next digit (8) from the dividend, add it to 337, then carry on: 3378 / 401

Moving on to step 6:
If we divide 3378 by 401, we get 8 and a remainder of 170.
Use 8 as the next digit of our solution. 
Result so far: 1418.0
If we take 3208 away from 3378, we end up with 170.
Bring next digit (6) of the dividend behind the 170 and repeat the process: 1706 / 401

Advancing to step 7:
The number 401 fits into 1706 4 times, leaving a remainder of 102.
The next digit of our result is 4. 
Result so far: 14184.0
The remainder is 102 after subtracting 1604 from 1706.
Include the next digit (6) from the dividend after 102, then repeat: 1026 / 401

On to step 8:
If we divide 1026 by 401, we get 2 and a remainder of 224.
The next digit of our result is 2. 
Result so far: 141842.0
Subtract 802 from 1026 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 9:
The number 401 fits into 2240 5 times, leaving a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 141842.5
If we subtract 2005 from 2240, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 10:
401 goes into 2350 5 times with a remainder of 345.
Use 5 as the next digit of our solution. 
Result so far: 141842.55
Subtract 2005 from 2350 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

In conclusion, the division gives 141842.55 with a balance of 0.345.
