Let's divide 721298 by 45
Let's see how many times 45 fits into 721298.

Going ahead to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 45

On to step 2:
45 can be fit into 72 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 72, we end up with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 45

Moving on to step 3:
The number 45 fits into 271 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 270 from 271 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 45

Step 4:
45 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 160.0
Subtract 0 from 12 to get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 45

Moving on to step 5:
When dividing 129 by 45, we get 2 with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 1602.0
Subtract 90 from 129 to get 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 45

Let's proceed to step 6:
398 divided by 45 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 16028.0
Subtract 360 from 398 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
45 goes into 380 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 16028.8
If we take 360 away from 380, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 45 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 16028.84
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 45 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 16028.844
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 16028.844 with a remainder of 0.002.
