We look at the division of 457189 by 9 
Our goal is to divide 457189 by 9.

Let's proceed to step 1:
9 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 9

On to step 2:
45 divided by 9 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 45 from 45 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 9

On to step 3:
If we divide 7 by 9, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 9

Moving on to step 4:
71 divided by 9 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 507.0
If we subtract 63 from 71, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 9

Going ahead to step 5:
9 can be fit into 88 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 5079.0
Deduct 81 from 88 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 9

Advancing to step 6:
9 goes into 79 8 times with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 50798.0
If we subtract 72 from 79, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
When dividing 70 by 9, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 50798.7
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
When dividing 70 by 9, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 50798.77
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 50798.77, and the remainder is 0.007.
