We divide 931291 by 45
Our goal is to divide 931291 by 45.

Let's proceed to step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 45

Step 2:
45 goes into 93 2 times with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 90 from 93 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 45

On to step 3:
45 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 31 to get 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 45

Going ahead to step 4:
312 divided by 45 is 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 206.0
Subtract 270 from 312 to get 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 45

Going ahead to step 5:
45 goes into 429 9 times with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 2069.0
If we take 405 away from 429, we end up with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 45

Let's proceed to step 6:
45 goes into 241 5 times with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 20695.0
Subtract 225 from 241 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 45 fits into 160 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 20695.3
If we subtract 135 from 160, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 20695.35
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
If we divide 250 by 45, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 20695.355
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 20695.355 and a remainder of 0.0025.
