72025563 ÷ 400 
Our goal is to divide 72025563 by 400.

Advancing to step 1:
When dividing 7 by 400, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 400

On to step 2:
When dividing 72 by 400, we get 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 400

Moving on to step 3:
400 can be fit into 720 1 times, resulting in a remainder of 320.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 400 from 720 and we're left with 320.
Take the next digit (2) from the dividend and append it to 320, then repeat: 3202 / 400

Advancing to step 4:
3202 divided by 400 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 3200 from 3202 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 400

Advancing to step 5:
400 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 180.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 400

On to step 6:
400 goes into 255 0 times with a remainder of 255.
The number 0 becomes the next digit in our result. 
Result so far: 1800.0
Subtract 0 from 255 to get 255.
Take the next digit (6) from the dividend and append it to 255, then repeat: 2556 / 400

Advancing to step 7:
When dividing 2556 by 400, we get 6 with a remainder of 156.
Record the quotient 6 as the next digit in the result. 
Result so far: 18006.0
The remainder is 156 after subtracting 2400 from 2556.
Include the next digit (3) from the dividend after 156, then repeat: 1563 / 400

Step 8:
The number 400 fits into 1563 3 times, leaving a remainder of 363.
Record the quotient 3 as the next digit in the result. 
Result so far: 180063.0
Deduct 1200 from 1563 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Moving on to step 9:
The number 400 fits into 3630 9 times, leaving a remainder of 30.
The next digit of our result is 9. 
Result so far: 180063.9
If we take 3600 away from 3630, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
400 goes into 300 0 times with a remainder of 300.
The next digit of our result is 0. 
Result so far: 180063.9
If we subtract 0 from 300, 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.

On to step 11:
3000 divided by 400 is 7 with a remainder of 200.
Write down 7 as next digit of the result. 
Result so far: 180063.907
If we subtract 2800 from 3000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
400 can be fit into 2000 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 180063.9075
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.

Moving 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: 180063.9075
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.

Moving on to step 14:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 180063.9075
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.

Our division results in 180063.9075 with a remaining 0.0.
