917984 ÷ 55 
We want to figure out the number of times 917984 can be divided by 55.

On to step 1:
The number 55 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 55

On to step 2:
55 can be fit into 91 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 55 from 91 leaves us with 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 55

Going ahead to step 3:
55 goes into 367 6 times with a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 330 from 367, we get 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 55

Step 4:
If we divide 379 by 55, we get 6 and a remainder of 49.
The next digit of our result is 6. 
Result so far: 166.0
Subtract 330 from 379 to get 49.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 55

Going ahead to step 5:
If we divide 498 by 55, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1669.0
If we take 495 away from 498, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 55

Step 6:
34 divided by 55 is 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 16690.0
Deduct 0 from 34 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
55 can be fit into 340 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 16690.6
If we subtract 330 from 340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 55 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 16690.61
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 16690.618
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
55 goes into 100 1 times with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 16690.6181
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
55 goes into 450 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 16690.61818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
55 goes into 100 1 times with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 16690.618181
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
450 divided by 55 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 16690.6181818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
100 divided by 55 is 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 16690.61818181
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 16690.61818181 with a remaining 4.5e-08.
