We're dividing 389091 by 46 
Let's see how many times 46 fits into 389091.

Step 1:
46 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 46

Going ahead to step 2:
46 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 46

Step 3:
The number 46 fits into 389 8 times, leaving a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 368 from 389 and we're left with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 46

Moving on to step 4:
210 divided by 46 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 84.0
The remainder is 26 after subtracting 184 from 210.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 46

On to step 5:
46 goes into 269 5 times with a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 845.0
If we subtract 230 from 269, we get 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 46

Step 6:
391 divided by 46 is 8 with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 8458.0
Subtract 368 from 391 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
When dividing 230 by 46, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8458.5
Deduct 230 from 230 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 46, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8458.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
46 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8458.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 8458.5 with a remaining 0.0.
