14856263 ÷ 400 
We want to divide 14856263 by 400.

Advancing to step 1:
When dividing 1 by 400, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 400

Step 2:
400 can be fit into 14 0 times, resulting in a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 400

Moving on to step 3:
The number 400 fits into 148 0 times, leaving a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 148 leaves us with 148.
Take the next digit (5) from the dividend and append it to 148, then repeat: 1485 / 400

Moving on to step 4:
400 goes into 1485 3 times with a remainder of 285.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1200 from 1485, we get 285.
Bring next digit (6) of the dividend behind the 285 and repeat the process: 2856 / 400

Let's proceed to step 5:
If we divide 2856 by 400, we get 7 and a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 2800 from 2856 to get 56.
Include the next digit (2) from the dividend after 56, then repeat: 562 / 400

Advancing to step 6:
562 divided by 400 is 1 with a remainder of 162.
The number 1 becomes the next digit in our result. 
Result so far: 371.0
The remainder is 162 after subtracting 400 from 562.
Append the next digit (6) from the dividend to 162 and continue with: 1626 / 400

Going ahead to step 7:
400 can be fit into 1626 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 3714.0
The remainder is 26 after subtracting 1600 from 1626.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 400

Moving on to step 8:
263 divided by 400 is 0 with a remainder of 263.
Write down 0 as next digit of the result. 
Result so far: 37140.0
Subtracting 0 from 263 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 9:
2630 divided by 400 is 6 with a remainder of 230.
The number 6 becomes the next digit in our result. 
Result so far: 37140.6
Deduct 2400 from 2630 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 10:
If we divide 2300 by 400, we get 5 and a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 37140.65
If we subtract 2000 from 2300, 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.

Step 11:
If we divide 3000 by 400, we get 7 and a remainder of 200.
The next digit of our result is 7. 
Result so far: 37140.657
Deduct 2800 from 3000 and we're left 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: 37140.6575
Subtracting 2000 from 2000 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.

Going ahead to 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: 37140.6575
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.

Let's proceed to step 14:
When dividing 0 by 400, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 37140.6575
If we take 0 away from 0, 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.

After the division, we end up with 37140.6575 and a remainder of 0.0.
