We look at the division of 521686 by 55 
Let's see how many times 55 fits into 521686.

Moving on to step 1:
If we divide 5 by 55, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 55

Step 2:
If we divide 52 by 55, we get 0 and a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 55

Step 3:
When dividing 521 by 55, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 495 from 521 leaves us with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 55

Advancing to step 4:
When dividing 266 by 55, we get 4 with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
The remainder is 46 after subtracting 220 from 266.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 55

On to step 5:
The number 55 fits into 468 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 948.0
Subtracting 440 from 468 leaves us with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 55

On to step 6:
When dividing 286 by 55, we get 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 9485.0
Deduct 275 from 286 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
55 can be fit into 110 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 9485.2
If we subtract 110 from 110, 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.

Going ahead to step 8:
55 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9485.2
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.

Let's proceed to step 9:
0 divided by 55 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9485.2
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 9485.2 and a remainder of 0.0.
