We divide 55756667 by 400
Our goal is to divide 55756667 by 400.

Let's proceed to step 1:
The number 400 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 400

Moving on to step 2:
400 can be fit into 55 0 times, resulting in a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 400

On to step 3:
The number 400 fits into 557 1 times, leaving a remainder of 157.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 400 from 557 leaves us with 157.
Bring next digit (5) of the dividend behind the 157 and repeat the process: 1575 / 400

Step 4:
If we divide 1575 by 400, we get 3 and a remainder of 375.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1200 away from 1575, we end up with 375.
Append the next digit (6) from the dividend to 375 and continue with: 3756 / 400

Let's proceed to step 5:
If we divide 3756 by 400, we get 9 and a remainder of 156.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Subtracting 3600 from 3756 leaves us with 156.
Fetch the next digit (6) from the dividend, attach it to 156 and continue: 1566 / 400

On to step 6:
400 can be fit into 1566 3 times, resulting in a remainder of 366.
Put 3 as the next digit of the answer. 
Result so far: 1393.0
If we subtract 1200 from 1566, we get 366.
Fetch the next digit (6) from the dividend, attach it to 366 and continue: 3666 / 400

Step 7:
3666 divided by 400 is 9 with a remainder of 66.
The next digit of our result is 9. 
Result so far: 13939.0
Deduct 3600 from 3666 and we're left with 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 400

Advancing to step 8:
667 divided by 400 is 1 with a remainder of 267.
Write down 1 as next digit of the result. 
Result so far: 139391.0
Subtracting 400 from 667 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Step 9:
400 goes into 2670 6 times with a remainder of 270.
The next digit of our result is 6. 
Result so far: 139391.6
Subtract 2400 from 2670 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 10:
The number 400 fits into 2700 6 times, leaving a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 139391.66
If we subtract 2400 from 2700, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 139391.66 and a remainder of 0.3.
