We divide 386456 by 89
We want to divide 386456 by 89.

Advancing to step 1:
The number 89 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 89

On to step 2:
89 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
Subtract 0 from 38 to get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 89

Going ahead to step 3:
89 goes into 386 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 30 after subtracting 356 from 386.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 89

Going ahead to step 4:
The number 89 fits into 304 3 times, leaving a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 267 from 304 and we're left with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 89

Going ahead to step 5:
89 goes into 375 4 times with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
If we subtract 356 from 375, we get 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 89

Step 6:
89 can be fit into 196 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 4342.0
If we subtract 178 from 196, 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.

Let's proceed to step 7:
The number 89 fits into 180 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 4342.2
If we take 178 away from 180, we end up 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.

Advancing to step 8:
89 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4342.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 89, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 4342.202
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.

On to step 10:
When dividing 220 by 89, we get 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 4342.2022
If we subtract 178 from 220, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 4342.2022 and a remainder of 0.00042.
