785251 ÷ 45 
We want to divide 785251 by 45.

On to step 1:
45 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 45

Advancing to step 2:
If we divide 78 by 45, we get 1 and a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 33 after subtracting 45 from 78.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 45

Step 3:
If we divide 335 by 45, we get 7 and a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 315 away from 335, we end up with 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 45

On to step 4:
202 divided by 45 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 174.0
If we take 180 away from 202, we end up with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 45

Step 5:
When dividing 225 by 45, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1745.0
The remainder is 0 after subtracting 225 from 225.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 45

Moving on to step 6:
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: 17450.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 45, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 17450.0
Deduct 0 from 10 and we're left 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.

Going ahead to step 8:
The number 45 fits into 100 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 17450.02
If we take 90 away from 100, 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.

Step 9:
If we divide 100 by 45, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 17450.022
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 17450.022 with a balance of 0.001.
