Let's divide 553964 by 75
Let's see how many times 75 fits into 553964.

On to step 1:
75 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 75

Going ahead to step 2:
75 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Grab the next digit (3) from the dividend, add it to 55, then carry on: 553 / 75

On to step 3:
75 goes into 553 7 times with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 525 from 553 and we're left with 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 75

Advancing to step 4:
75 can be fit into 289 3 times, resulting in a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we take 225 away from 289, we end up with 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 75

Let's proceed to step 5:
If we divide 646 by 75, we get 8 and a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 738.0
Subtracting 600 from 646 leaves us with 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 75

Moving on to step 6:
75 goes into 464 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 7386.0
Subtract 450 from 464 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
If we divide 140 by 75, we get 1 and a remainder of 65.
The next digit of our result is 1. 
Result so far: 7386.1
If we subtract 75 from 140, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
The number 75 fits into 650 8 times, leaving a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 7386.18
Deduct 600 from 650 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 75, we get 6 and a remainder of 50.
The next digit of our result is 6. 
Result so far: 7386.186
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
When dividing 500 by 75, we get 6 with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 7386.1866
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 7386.1866, and the remainder is 0.0005.
