We divide 721154 by 45
We want to divide 721154 by 45.

Let's proceed to step 1:
45 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 45

Step 2:
The number 45 fits into 72 1 times, leaving a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 27 after subtracting 45 from 72.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 45

Moving on to step 3:
The number 45 fits into 271 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 270 from 271, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 45

Let's proceed to step 4:
The number 45 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 45

Going ahead to step 5:
45 can be fit into 115 2 times, resulting in a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 1602.0
If we take 90 away from 115, we end up with 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 45

Let's proceed to step 6:
45 goes into 254 5 times with a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 16025.0
Deduct 225 from 254 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
The number 45 fits into 290 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 16025.6
The remainder is 20 after subtracting 270 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 16025.64
If we take 180 away from 200, 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.

Advancing to step 9:
45 goes into 200 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 16025.644
Subtract 180 from 200 to get 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 outcome is 16025.644, with a leftover of 0.002.
