We look at the division of 391050 by 89 
We want to divide 391050 by 89.

Going ahead to step 1:
The number 89 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 89

Step 2:
When dividing 39 by 89, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 89

Going ahead to step 3:
If we divide 391 by 89, we get 4 and a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 35 after subtracting 356 from 391.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 89

Going ahead to step 4:
350 divided by 89 is 3 with a remainder of 83.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 83 after subtracting 267 from 350.
Append the next digit (5) from the dividend to 83 and continue with: 835 / 89

Moving on to step 5:
The number 89 fits into 835 9 times, leaving a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 439.0
Subtracting 801 from 835 leaves us with 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 89

Going ahead to step 6:
The number 89 fits into 340 3 times, leaving a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 4393.0
The remainder is 73 after subtracting 267 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
The number 89 fits into 730 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 4393.8
If we subtract 712 from 730, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
89 can be fit into 180 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 4393.82
Deduct 178 from 180 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
If we divide 20 by 89, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4393.82
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
If we divide 200 by 89, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 4393.8202
If we take 178 away from 200, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
The number 89 fits into 220 2 times, leaving a remainder of 42.
The next digit of our result is 2. 
Result so far: 4393.82022
If we take 178 away from 220, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 4393.82022 with a remaining 4.2e-05.
