63828261 ÷ 400 
Let's see how many times 400 fits into 63828261.

Step 1:
6 divided by 400 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 400

Moving on to step 2:
400 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 400

Going ahead to step 3:
If we divide 638 by 400, we get 1 and a remainder of 238.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 400 from 638, we get 238.
Grab the next digit (2) from the dividend, add it to 238, then carry on: 2382 / 400

On to step 4:
400 can be fit into 2382 5 times, resulting in a remainder of 382.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2000 away from 2382, we end up with 382.
Take the next digit (8) from the dividend and append it to 382, then repeat: 3828 / 400

Moving on to step 5:
If we divide 3828 by 400, we get 9 and a remainder of 228.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Subtract 3600 from 3828 to get 228.
Fetch the next digit (2) from the dividend, attach it to 228 and continue: 2282 / 400

Advancing to step 6:
When dividing 2282 by 400, we get 5 with a remainder of 282.
The number 5 becomes the next digit in our result. 
Result so far: 1595.0
Deduct 2000 from 2282 and we're left with 282.
Append the next digit (6) from the dividend to 282 and continue with: 2826 / 400

Step 7:
The number 400 fits into 2826 7 times, leaving a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 15957.0
The remainder is 26 after subtracting 2800 from 2826.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 400

Let's proceed to step 8:
When dividing 261 by 400, we get 0 with a remainder of 261.
The next digit of our result is 0. 
Result so far: 159570.0
If we take 0 away from 261, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 9:
2610 divided by 400 is 6 with a remainder of 210.
The next digit of our result is 6. 
Result so far: 159570.6
Subtract 2400 from 2610 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
400 can be fit into 2100 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 159570.65
If we subtract 2000 from 2100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
400 can be fit into 1000 2 times, resulting in a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 159570.652
Subtracting 800 from 1000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
400 goes into 2000 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 159570.6525
If we take 2000 away from 2000, we end up 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.

Step 13:
0 divided by 400 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 159570.6525
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.

Going ahead to step 14:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 159570.6525
If we subtract 0 from 0, we 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.

After the division, we end up with 159570.6525 and a remainder of 0.0.
