We look at the division of 489072 by 75 
We want to figure out the number of times 489072 can be divided by 75.

Moving on to step 1:
75 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 75

On to step 2:
48 divided by 75 is 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 75

Advancing to step 3:
489 divided by 75 is 6 with a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 450 from 489 and we're left with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 75

Going ahead to step 4:
75 can be fit into 390 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 65.0
If we take 375 away from 390, we end up with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 75

Moving on to step 5:
If we divide 157 by 75, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 652.0
If we take 150 away from 157, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 75

Going ahead to step 6:
75 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 6520.0
Subtract 0 from 72 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 7:
The number 75 fits into 720 9 times, leaving a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 6520.9
Deduct 675 from 720 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
The number 75 fits into 450 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6520.96
If we take 450 away from 450, 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.

Advancing to step 9:
0 divided by 75 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6520.96
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.

Advancing to step 10:
75 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6520.96
Deduct 0 from 0 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.

The final outcome is 6520.96, with a leftover of 0.0.
