We look at the division of 405639 by 88 
Our goal is to divide 405639 by 88.

Moving on to step 1:
4 divided by 88 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 88

Going ahead to step 2:
If we divide 40 by 88, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 88

Let's proceed to step 3:
If we divide 405 by 88, we get 4 and a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 352 from 405 to get 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 88

Step 4:
When dividing 536 by 88, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtracting 528 from 536 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 88

Going ahead to step 5:
83 divided by 88 is 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 460.0
If we take 0 away from 83, we end up with 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 88

Going ahead to step 6:
When dividing 839 by 88, we get 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 4609.0
If we take 792 away from 839, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
When dividing 470 by 88, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 4609.5
Subtracting 440 from 470 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
88 goes into 300 3 times with a remainder of 36.
The next digit of our result is 3. 
Result so far: 4609.53
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
The number 88 fits into 360 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4609.534
The remainder is 8 after subtracting 352 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
88 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 4609.534
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
800 divided by 88 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 4609.53409
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
88 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4609.53409
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
800 divided by 88 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 4609.5340909
If we subtract 792 from 800, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
If we divide 80 by 88, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 4609.5340909
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 4609.5340909, with a leftover of 8e-08.
