We're dividing 31827403 by 45 
Let's see how many times 45 fits into 31827403.

Step 1:
If we divide 3 by 45, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 45

Going ahead to step 2:
When dividing 31 by 45, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 45

Let's proceed to step 3:
45 goes into 318 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 315 from 318 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 45

Let's proceed to step 4:
The number 45 fits into 32 0 times, leaving a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 70.0
Deduct 0 from 32 and we're left with 32.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 45

Moving on to step 5:
327 divided by 45 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 707.0
Deduct 315 from 327 and we're left with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 45

Step 6:
The number 45 fits into 124 2 times, leaving a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 7072.0
If we subtract 90 from 124, we get 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 45

Step 7:
When dividing 340 by 45, we get 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 70727.0
Subtracting 315 from 340 leaves us with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 45

On to step 8:
When dividing 253 by 45, we get 5 with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 707275.0
Subtracting 225 from 253 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
If we divide 280 by 45, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 707275.6
If we take 270 away from 280, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
100 divided by 45 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 707275.62
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
45 can be fit into 100 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 707275.622
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 707275.622 and a remainder of 0.001.
