We're dividing 55647134 by 400 
Our goal is to divide 55647134 by 400.

Advancing to step 1:
If we divide 5 by 400, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 400

Moving on to step 2:
400 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Include the next digit (6) from the dividend after 55, then repeat: 556 / 400

Let's proceed to step 3:
400 goes into 556 1 times with a remainder of 156.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 400 from 556 to get 156.
Bring next digit (4) of the dividend behind the 156 and repeat the process: 1564 / 400

Step 4:
400 can be fit into 1564 3 times, resulting in a remainder of 364.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1200 away from 1564, we end up with 364.
Include the next digit (7) from the dividend after 364, then repeat: 3647 / 400

On to step 5:
When dividing 3647 by 400, we get 9 with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Subtract 3600 from 3647 to get 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 400

On to step 6:
400 can be fit into 471 1 times, resulting in a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 1391.0
If we take 400 away from 471, we end up with 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 400

Moving on to step 7:
If we divide 713 by 400, we get 1 and a remainder of 313.
Use 1 as the next digit of our solution. 
Result so far: 13911.0
Deduct 400 from 713 and we're left with 313.
Append the next digit (4) from the dividend to 313 and continue with: 3134 / 400

Moving on to step 8:
The number 400 fits into 3134 7 times, leaving a remainder of 334.
Put 7 as the next digit of the answer. 
Result so far: 139117.0
If we subtract 2800 from 3134, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 9:
3340 divided by 400 is 8 with a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 139117.8
Subtract 3200 from 3340 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
1400 divided by 400 is 3 with a remainder of 200.
The number 3 becomes the next digit in our result. 
Result so far: 139117.83
The remainder is 200 after subtracting 1200 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
The number 400 fits into 2000 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 139117.835
Deduct 2000 from 2000 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 139117.835
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
When dividing 0 by 400, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 139117.835
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 139117.835 with a balance of 0.0.
