56390 ÷ 88 
Let's see how many times 88 fits into 56390.

Going ahead to step 1:
88 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 88

Going ahead to step 2:
If we divide 56 by 88, we get 0 and a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Include the next digit (3) from the dividend after 56, then repeat: 563 / 88

Let's proceed to step 3:
The number 88 fits into 563 6 times, leaving a remainder of 35.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 528 from 563 leaves us with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 88

Let's proceed to step 4:
The number 88 fits into 359 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
The remainder is 7 after subtracting 352 from 359.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 88

Moving on to step 5:
The number 88 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 640.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 6:
88 goes into 700 7 times with a remainder of 84.
Put 7 as the next digit of the answer. 
Result so far: 640.7
Subtracting 616 from 700 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 7:
88 goes into 840 9 times with a remainder of 48.
The next digit of our result is 9. 
Result so far: 640.79
If we take 792 away from 840, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
The number 88 fits into 480 5 times, leaving a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 640.795
Subtracting 440 from 480 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:
The number 88 fits into 400 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 640.7954
If we take 352 away from 400, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
If we divide 480 by 88, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 640.79545
Subtract 440 from 480 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 88 is 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 640.795454
Subtract 352 from 400 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
88 can be fit into 480 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 640.7954545
If we subtract 440 from 480, we get 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 13:
88 goes into 400 4 times with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 640.79545454
The remainder is 48 after subtracting 352 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 640.79545454, with a leftover of 4.8e-08.
