We're dividing 744586 by 45 
Our goal is to divide 744586 by 45.

Advancing to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 45

Moving on to step 2:
74 divided by 45 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 74, we get 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 45

Advancing to step 3:
45 can be fit into 294 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 24 after subtracting 270 from 294.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 45

Advancing to step 4:
If we divide 245 by 45, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 165.0
The remainder is 20 after subtracting 225 from 245.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 45

Moving on to step 5:
The number 45 fits into 208 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 1654.0
Subtract 180 from 208 to get 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 45

Advancing to step 6:
The number 45 fits into 286 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 16546.0
Subtracting 270 from 286 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
The number 45 fits into 160 3 times, leaving a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 16546.3
Subtracting 135 from 160 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
250 divided by 45 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 16546.35
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
250 divided by 45 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 16546.355
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 16546.355, and the remainder is 0.0025.
