We're dividing 57557820 by 400 
Our goal is to divide 57557820 by 400.

Step 1:
When dividing 5 by 400, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 400

Let's proceed to step 2:
If we divide 57 by 400, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 400

Let's proceed to step 3:
If we divide 575 by 400, we get 1 and a remainder of 175.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 400 from 575 leaves us with 175.
Take the next digit (5) from the dividend and append it to 175, then repeat: 1755 / 400

Going ahead to step 4:
1755 divided by 400 is 4 with a remainder of 155.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 1600 from 1755 leaves us with 155.
Bring next digit (7) of the dividend behind the 155 and repeat the process: 1557 / 400

Advancing to step 5:
The number 400 fits into 1557 3 times, leaving a remainder of 357.
Write down 3 as next digit of the result. 
Result so far: 143.0
If we take 1200 away from 1557, we end up with 357.
Append the next digit (8) from the dividend to 357 and continue with: 3578 / 400

Moving on to step 6:
400 goes into 3578 8 times with a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 1438.0
Deduct 3200 from 3578 and we're left with 378.
Include the next digit (2) from the dividend after 378, then repeat: 3782 / 400

Step 7:
400 goes into 3782 9 times with a remainder of 182.
The number 9 becomes the next digit in our result. 
Result so far: 14389.0
Deduct 3600 from 3782 and we're left with 182.
Fetch the next digit (0) from the dividend, attach it to 182 and continue: 1820 / 400

Advancing to step 8:
400 goes into 1820 4 times with a remainder of 220.
The next digit of our result is 4. 
Result so far: 143894.0
If we subtract 1600 from 1820, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 9:
If we divide 2200 by 400, we get 5 and a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 143894.5
Subtract 2000 from 2200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
When dividing 2000 by 400, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 143894.55
The remainder is 0 after subtracting 2000 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 143894.55 with a remainder of 0.0.
