521964 divided by 55 
Let's see how many times 55 fits into 521964.

Step 1:
When dividing 5 by 55, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 55

Advancing to step 2:
55 can be fit into 52 0 times, resulting in a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 55

Let's proceed to step 3:
521 divided by 55 is 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 495 from 521 and we're left with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 55

Going ahead to step 4:
If we divide 269 by 55, we get 4 and a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Deduct 220 from 269 and we're left with 49.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 55

Moving on to step 5:
55 can be fit into 496 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 949.0
Subtracting 495 from 496 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 55

Let's proceed to step 6:
55 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 9490.0
Subtract 0 from 14 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
If we divide 140 by 55, we get 2 and a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 9490.2
Deduct 110 from 140 and we're left 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.

On to step 8:
When dividing 300 by 55, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 9490.25
Subtracting 275 from 300 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
250 divided by 55 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 9490.254
If we take 220 away from 250, we end up 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.

On to step 10:
55 goes into 300 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 9490.2545
Subtracting 275 from 300 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
55 goes into 250 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 9490.25454
Deduct 220 from 250 and we're left 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.

Let's proceed to step 12:
55 can be fit into 300 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 9490.254545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
The number 55 fits into 250 4 times, leaving a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 9490.2545454
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
55 goes into 300 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 9490.25454545
Subtract 275 from 300 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 9490.25454545 and a remainder of 2.5e-08.
