355821 divided by 75 
Our goal is to divide 355821 by 75.

Going ahead to step 1:
3 divided by 75 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 75

Going ahead to step 2:
When dividing 35 by 75, we get 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 75

Moving on to step 3:
75 goes into 355 4 times with a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 300 away from 355, we end up with 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 75

Advancing to step 4:
The number 75 fits into 558 7 times, leaving a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 525 from 558, we get 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 75

On to step 5:
75 goes into 332 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
If we take 300 away from 332, we end up with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 75

Let's proceed to step 6:
75 can be fit into 321 4 times, resulting in a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 4744.0
Subtract 300 from 321 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 75, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 4744.2
Deduct 150 from 210 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
75 goes into 600 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 4744.28
Subtracting 600 from 600 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 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4744.28
The remainder is 0 after subtracting 0 from 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 10:
If we divide 0 by 75, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4744.28
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.

The final result is 4744.28 with a remainder of 0.0.
