54726624 ÷ 400 
Let's see how many times 400 fits into 54726624.

Moving on to step 1:
400 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 400

Going ahead to step 2:
The number 400 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 400

Step 3:
When dividing 547 by 400, we get 1 with a remainder of 147.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 400 from 547 and we're left with 147.
Append the next digit (2) from the dividend to 147 and continue with: 1472 / 400

Step 4:
400 goes into 1472 3 times with a remainder of 272.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 272 after subtracting 1200 from 1472.
Include the next digit (6) from the dividend after 272, then repeat: 2726 / 400

Advancing to step 5:
When dividing 2726 by 400, we get 6 with a remainder of 326.
Write down 6 as next digit of the result. 
Result so far: 136.0
Subtracting 2400 from 2726 leaves us with 326.
Take the next digit (6) from the dividend and append it to 326, then repeat: 3266 / 400

Let's proceed to step 6:
When dividing 3266 by 400, we get 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 1368.0
If we subtract 3200 from 3266, we get 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 400

Going ahead to step 7:
400 can be fit into 662 1 times, resulting in a remainder of 262.
The next digit of our result is 1. 
Result so far: 13681.0
If we take 400 away from 662, we end up with 262.
Take the next digit (4) from the dividend and append it to 262, then repeat: 2624 / 400

Step 8:
If we divide 2624 by 400, we get 6 and a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 136816.0
Subtracting 2400 from 2624 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 9:
2240 divided by 400 is 5 with a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 136816.5
If we take 2000 away from 2240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
400 can be fit into 2400 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 136816.56
Subtracting 2400 from 2400 leaves us 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 11:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 136816.56
Subtracting 0 from 0 leaves us 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.

Advancing to step 12:
When dividing 0 by 400, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 136816.56
Subtract 0 from 0 to get 0.
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 outcome is 136816.56, with a leftover of 0.0.
