405984 ÷ 88 
We want to figure out the number of times 405984 can be divided by 88.

Moving on to step 1:
88 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 88

Moving on to step 2:
40 divided by 88 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 88

Advancing to step 3:
The number 88 fits into 405 4 times, leaving a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 352 from 405, we get 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 88

Moving on to step 4:
539 divided by 88 is 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we take 528 away from 539, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 88

Advancing to step 5:
If we divide 118 by 88, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 461.0
If we take 88 away from 118, we end up with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 88

Let's proceed to step 6:
88 goes into 304 3 times with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 4613.0
Deduct 264 from 304 and we're left 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 7:
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: 4613.4
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.

Going ahead to step 8:
When dividing 480 by 88, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 4613.45
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.

Let's proceed to step 9:
400 divided by 88 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 4613.454
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.

Going ahead to step 10:
88 can be fit into 480 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 4613.4545
Deduct 440 from 480 and we're left 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.

Step 11:
88 can be fit into 400 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 4613.45454
Subtracting 352 from 400 leaves us 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 12:
88 can be fit into 480 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 4613.454545
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.

Going ahead to step 13:
400 divided by 88 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 4613.4545454
Deduct 352 from 400 and we're left 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.

Step 14:
480 divided by 88 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 4613.45454545
If we take 440 away from 480, we end up 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.

Our division results in 4613.45454545 with a remaining 4e-08.
