Let's divide 128590 by 48
We want to divide 128590 by 48.

Advancing to step 1:
48 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 48

Moving on to step 2:
The number 48 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 48

Step 3:
If we divide 128 by 48, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 96 from 128 and we're left with 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 48

Advancing to step 4:
48 goes into 325 6 times with a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtracting 288 from 325 leaves us with 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 48

Advancing to step 5:
379 divided by 48 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
The remainder is 43 after subtracting 336 from 379.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 48

On to step 6:
The number 48 fits into 430 8 times, leaving a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 2678.0
If we subtract 384 from 430, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
If we divide 460 by 48, we get 9 and a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 2678.9
Subtract 432 from 460 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
If we divide 280 by 48, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 2678.95
Subtracting 240 from 280 leaves us 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.

Moving on to step 9:
If we divide 400 by 48, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 2678.958
Subtract 384 from 400 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
If we divide 160 by 48, we get 3 and a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 2678.9583
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
48 can be fit into 160 3 times, resulting in a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 2678.95833
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 2678.95833 with a balance of 1.6e-05.
