Let's divide 13080531 by 45
We're looking to find how many times 45 goes into 13080531.

Advancing to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 45

Moving on to step 2:
45 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 45

Advancing to step 3:
When dividing 130 by 45, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 2.0
If we take 90 away from 130, we end up with 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 45

Advancing to step 4:
408 divided by 45 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 405 from 408 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 45

Step 5:
When dividing 30 by 45, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 290.0
Subtract 0 from 30 to get 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 45

Going ahead to step 6:
The number 45 fits into 305 6 times, leaving a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 2906.0
If we take 270 away from 305, we end up with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 45

On to step 7:
353 divided by 45 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 29067.0
If we subtract 315 from 353, we get 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 45

Going ahead to step 8:
381 divided by 45 is 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 290678.0
Subtracting 360 from 381 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
45 can be fit into 210 4 times, resulting in a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 290678.4
If we take 180 away from 210, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 45 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 290678.46
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 290678.466
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 290678.466 and a remainder of 0.003.
