We look at the division of 721456 by 55 
Our goal is to divide 721456 by 55.

On to step 1:
7 divided by 55 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 55

Step 2:
If we divide 72 by 55, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
If we take 55 away from 72, we end up with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 55

Advancing to step 3:
171 divided by 55 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 165 from 171, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 55

Moving on to step 4:
When dividing 64 by 55, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
If we subtract 55 from 64, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 55

Let's proceed to step 5:
The number 55 fits into 95 1 times, leaving a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1311.0
If we take 55 away from 95, we end up with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 55

Going ahead to step 6:
55 can be fit into 406 7 times, resulting in a remainder of 21.
The next digit of our result is 7. 
Result so far: 13117.0
Deduct 385 from 406 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
The number 55 fits into 210 3 times, leaving a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 13117.3
Subtract 165 from 210 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
55 goes into 450 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 13117.38
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 55 fits into 100 1 times, leaving a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 13117.381
If we take 55 away from 100, we end up 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.

Moving on to step 10:
450 divided by 55 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 13117.3818
Subtract 440 from 450 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
100 divided by 55 is 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 13117.38181
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
55 goes into 450 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 13117.381818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
When dividing 100 by 55, we get 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 13117.3818181
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
450 divided by 55 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 13117.38181818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 13117.38181818 and a remainder of 1e-08.
