Let's divide 600091 by 45
We want to figure out the number of times 600091 can be divided by 45.

Advancing to step 1:
6 divided by 45 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 45

Going ahead to step 2:
When dividing 60 by 45, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 45 from 60 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 45

Moving on to step 3:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 135 away from 150, we end up with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 45

On to step 4:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 133.0
Subtract 135 from 150 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 45

Advancing to step 5:
If we divide 159 by 45, we get 3 and a remainder of 24.
The next digit of our result is 3. 
Result so far: 1333.0
The remainder is 24 after subtracting 135 from 159.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 45

Moving on to step 6:
45 goes into 241 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 13335.0
If we subtract 225 from 241, we 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.

Moving on to step 7:
160 divided by 45 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 13335.3
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 13335.35
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to 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: 13335.355
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.

The quotient of the division is 13335.355, and the remainder is 0.0025.
