We look at the division of 75147534 by 400 
We want to figure out the number of times 75147534 can be divided by 400.

Advancing to step 1:
7 divided by 400 is 0 with 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

Let's proceed to step 2:
When dividing 75 by 400, we get 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 400

On to step 3:
If we divide 751 by 400, we get 1 and a remainder of 351.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 400 away from 751, we end up with 351.
Bring next digit (4) of the dividend behind the 351 and repeat the process: 3514 / 400

Step 4:
3514 divided by 400 is 8 with a remainder of 314.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 3200 from 3514, we get 314.
Bring next digit (7) of the dividend behind the 314 and repeat the process: 3147 / 400

Step 5:
3147 divided by 400 is 7 with a remainder of 347.
Put 7 as the next digit of the answer. 
Result so far: 187.0
Subtracting 2800 from 3147 leaves us with 347.
Fetch the next digit (5) from the dividend, attach it to 347 and continue: 3475 / 400

Moving on to step 6:
400 can be fit into 3475 8 times, resulting in a remainder of 275.
Write down 8 as next digit of the result. 
Result so far: 1878.0
Deduct 3200 from 3475 and we're left with 275.
Include the next digit (3) from the dividend after 275, then repeat: 2753 / 400

Moving on to step 7:
400 can be fit into 2753 6 times, resulting in a remainder of 353.
The number 6 becomes the next digit in our result. 
Result so far: 18786.0
Deduct 2400 from 2753 and we're left with 353.
Append the next digit (4) from the dividend to 353 and continue with: 3534 / 400

Advancing to step 8:
The number 400 fits into 3534 8 times, leaving a remainder of 334.
Record the quotient 8 as the next digit in the result. 
Result so far: 187868.0
The remainder is 334 after subtracting 3200 from 3534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 9:
3340 divided by 400 is 8 with a remainder of 140.
Write down 8 as next digit of the result. 
Result so far: 187868.8
Deduct 3200 from 3340 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
1400 divided by 400 is 3 with a remainder of 200.
The next digit of our result is 3. 
Result so far: 187868.83
If we take 1200 away from 1400, we end up 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.

Let's proceed to step 11:
When dividing 2000 by 400, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 187868.835
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.

On to step 12:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 187868.835
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 13:
When dividing 0 by 400, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 187868.835
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.

After the division, we end up with 187868.835 and a remainder of 0.0.
