558990 ÷ 72 
We want to figure out the number of times 558990 can be divided by 72.

Let's proceed to step 1:
5 divided by 72 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 72

Advancing to step 2:
72 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 72

On to step 3:
The number 72 fits into 558 7 times, leaving a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 54 after subtracting 504 from 558.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 72

Moving on to step 4:
72 can be fit into 549 7 times, resulting in a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Deduct 504 from 549 and we're left with 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 72

Advancing to step 5:
If we divide 459 by 72, we get 6 and a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 776.0
Subtracting 432 from 459 leaves us with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 72

On to step 6:
If we divide 270 by 72, we get 3 and a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 7763.0
If we take 216 away from 270, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
If we divide 540 by 72, we get 7 and a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 7763.7
Subtracting 504 from 540 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
The number 72 fits into 360 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7763.75
Deduct 360 from 360 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.

Moving on to step 9:
72 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7763.75
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.

On to step 10:
If we divide 0 by 72, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7763.75
If we take 0 away from 0, 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.

The quotient of the division is 7763.75, and the remainder is 0.0.
