391138 ÷ 88 
Our goal is to divide 391138 by 88.

Advancing to step 1:
88 goes into 3 0 times with 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.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 88

On to step 2:
If we divide 39 by 88, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 88

Moving on to step 3:
88 goes into 391 4 times with a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 352 from 391 to get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 88

On to step 4:
88 can be fit into 391 4 times, resulting in a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtracting 352 from 391 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 88

Moving on to step 5:
393 divided by 88 is 4 with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 444.0
If we take 352 away from 393, we end up with 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 88

Step 6:
88 can be fit into 418 4 times, resulting in a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 4444.0
Subtracting 352 from 418 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 7:
When dividing 660 by 88, we get 7 with a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 4444.7
Subtracting 616 from 660 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
The number 88 fits into 440 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 4444.75
If we subtract 440 from 440, we get 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:
88 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4444.75
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.

Step 10:
0 divided by 88 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4444.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4444.75 and a remainder of 0.0.
