669303 divided by 40 
We want to divide 669303 by 40.

Going ahead to step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 40

Step 2:
The number 40 fits into 66 1 times, leaving a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 40 from 66 and we're left with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 40

Step 3:
40 can be fit into 269 6 times, resulting in a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 240 from 269 to get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 40

Moving on to step 4:
293 divided by 40 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
If we subtract 280 from 293, we get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 40

Step 5:
40 can be fit into 130 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 1673.0
Subtract 120 from 130 to get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 40

Going ahead to step 6:
40 can be fit into 103 2 times, resulting in a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 16732.0
If we subtract 80 from 103, we 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:
When dividing 230 by 40, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 16732.5
The remainder is 30 after subtracting 200 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 40 is 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 16732.57
Deduct 280 from 300 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:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 16732.575
If we subtract 200 from 200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16732.575
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16732.575
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 16732.575 with a remainder of 0.0.
