721556 ÷ 10 
We're looking to find how many times 10 goes into 721556.

On to step 1:
If we divide 7 by 10, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 10

Advancing to step 2:
When dividing 72 by 10, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 70 from 72 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 10

Let's proceed to step 3:
21 divided by 10 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 1 after subtracting 20 from 21.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 10

On to step 4:
The number 10 fits into 15 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 721.0
If we subtract 10 from 15, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 10

Advancing to step 5:
10 goes into 55 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7215.0
If we take 50 away from 55, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 10

Let's proceed to step 6:
When dividing 56 by 10, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 72155.0
Deduct 50 from 56 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 10, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 72155.6
Deduct 60 from 60 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 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 72155.6
Subtracting 0 from 0 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.

Let's proceed to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 72155.6
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.

Our division results in 72155.6 with a remaining 0.0.
