We look at the division of 75921 by 10 
Let's see how many times 10 fits into 75921.

On to step 1:
10 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 10

Advancing to step 2:
10 goes into 75 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 70 from 75 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 10

Step 3:
The number 10 fits into 59 5 times, leaving a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we take 50 away from 59, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 10

Advancing to step 4:
10 can be fit into 92 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 759.0
If we subtract 90 from 92, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 10

On to step 5:
If we divide 21 by 10, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 7592.0
Subtracting 20 from 21 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 6:
10 can be fit into 10 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 7592.1
Deduct 10 from 10 and we're left 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 7:
10 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7592.1
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.

Advancing to step 8:
10 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: 7592.1
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.

The final outcome is 7592.1, with a leftover of 0.0.
