We're dividing 75280359 by 400 
We want to figure out the number of times 75280359 can be divided by 400.

On to step 1:
400 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 400

Moving on to step 2:
400 goes into 75 0 times with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 400

On to step 3:
When dividing 752 by 400, we get 1 with a remainder of 352.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 400 from 752 and we're left with 352.
Grab the next digit (8) from the dividend, add it to 352, then carry on: 3528 / 400

Let's proceed to step 4:
400 can be fit into 3528 8 times, resulting in a remainder of 328.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 3200 from 3528 to get 328.
Bring next digit (0) of the dividend behind the 328 and repeat the process: 3280 / 400

Going ahead to step 5:
400 goes into 3280 8 times with a remainder of 80.
The next digit of our result is 8. 
Result so far: 188.0
Subtract 3200 from 3280 to get 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 400

Step 6:
If we divide 803 by 400, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 1882.0
The remainder is 3 after subtracting 800 from 803.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 400

Going ahead to step 7:
The number 400 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 18820.0
Subtract 0 from 35 to get 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 400

On to step 8:
The number 400 fits into 359 0 times, leaving a remainder of 359.
Use 0 as the next digit of our solution. 
Result so far: 188200.0
Subtracting 0 from 359 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Let's proceed to step 9:
If we divide 3590 by 400, we get 8 and a remainder of 390.
Record the quotient 8 as the next digit in the result. 
Result so far: 188200.8
Subtract 3200 from 3590 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
400 goes into 3900 9 times with a remainder of 300.
Put 9 as the next digit of the answer. 
Result so far: 188200.89
If we take 3600 away from 3900, we end up with 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:
400 can be fit into 3000 7 times, resulting in a remainder of 200.
The number 7 becomes the next digit in our result. 
Result so far: 188200.897
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.

Step 12:
400 can be fit into 2000 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 188200.8975
Subtract 2000 from 2000 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 13:
0 divided by 400 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 188200.8975
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.

Moving on to step 14:
400 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 188200.8975
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.

In conclusion, the division gives 188200.8975 with a balance of 0.0.
