Let's divide 3142503 by 45
We want to divide 3142503 by 45.

Going ahead to step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 45

Moving on to step 2:
When dividing 31 by 45, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 45

On to step 3:
The number 45 fits into 314 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 44 after subtracting 270 from 314.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 45

Going ahead to step 4:
45 goes into 442 9 times with a remainder of 37.
The next digit of our result is 9. 
Result so far: 69.0
If we take 405 away from 442, we end up with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 45

Moving on to step 5:
375 divided by 45 is 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 698.0
Subtracting 360 from 375 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 45

Moving on to step 6:
45 goes into 150 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 6983.0
If we subtract 135 from 150, we get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 45

Moving on to step 7:
If we divide 153 by 45, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 69833.0
The remainder is 18 after subtracting 135 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
45 goes into 180 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 69833.4
Deduct 180 from 180 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 9:
0 divided by 45 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 69833.4
Subtracting 0 from 0 leaves us 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.

Moving on to step 10:
If we divide 0 by 45, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 69833.4
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.

The final result is 69833.4 with a remainder of 0.0.
