We look at the division of 191443 by 45 
We want to figure out the number of times 191443 can be divided by 45.

Let's proceed to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 45

On to step 2:
If we divide 19 by 45, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 45

Going ahead to step 3:
When dividing 191 by 45, we get 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 180 from 191 to get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 45

Step 4:
114 divided by 45 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 90 from 114 to get 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 45

On to step 5:
45 goes into 244 5 times with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 425.0
If we take 225 away from 244, we end up with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 45

Step 6:
If we divide 193 by 45, we get 4 and a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4254.0
Subtracting 180 from 193 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
45 goes into 130 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 4254.2
Subtract 90 from 130 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
45 goes into 400 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 4254.28
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 4254.288
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 4254.288 with a remainder of 0.004.
