Let's divide 311809 by 45
Let's see how many times 45 fits into 311809.

Step 1:
If we divide 3 by 45, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 45

Advancing to step 2:
45 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 45

Let's proceed to step 3:
45 can be fit into 311 6 times, resulting in a remainder of 41.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 270 from 311 to get 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 45

Advancing to step 4:
If we divide 418 by 45, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 69.0
The remainder is 13 after subtracting 405 from 418.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 45

Advancing to step 5:
130 divided by 45 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 692.0
The remainder is 40 after subtracting 90 from 130.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 45

Advancing to step 6:
409 divided by 45 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 6929.0
The remainder is 4 after subtracting 405 from 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 45 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6929.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
400 divided by 45 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 6929.08
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 45, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 6929.088
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 6929.088, with a leftover of 0.004.
