Let's divide 673718 by 45
We're looking to find how many times 45 goes into 673718.

Step 1:
When dividing 6 by 45, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 45

Let's proceed to step 2:
The number 45 fits into 67 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 67 and we're left with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 45

On to step 3:
The number 45 fits into 223 4 times, leaving a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 180 from 223 leaves us with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 45

Moving on to step 4:
When dividing 437 by 45, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
Subtract 405 from 437 to get 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 45

On to step 5:
45 can be fit into 321 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 1497.0
Subtract 315 from 321 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 45

Moving on to step 6:
68 divided by 45 is 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 14971.0
Subtract 45 from 68 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
230 divided by 45 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 14971.5
If we subtract 225 from 230, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 14971.51
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 14971.511
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 14971.511 with a remaining 0.0005.
