521228 divided by 55 
We're looking to find how many times 55 goes into 521228.

Let's proceed to step 1:
When dividing 5 by 55, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 55

Moving on to step 2:
55 can be fit into 52 0 times, resulting in a remainder of 52.
Use 0 as the next digit of our solution. 
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

Advancing 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
The remainder is 26 after subtracting 495 from 521.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 55

Advancing to step 4:
262 divided by 55 is 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 94.0
Deduct 220 from 262 and we're left with 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 55

Moving on to step 5:
55 can be fit into 422 7 times, resulting in a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 947.0
The remainder is 37 after subtracting 385 from 422.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 55

Step 6:
If we divide 378 by 55, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 9476.0
If we subtract 330 from 378, we 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.

Step 7:
55 goes into 480 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 9476.8
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.

On to step 8:
400 divided by 55 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 9476.87
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
150 divided by 55 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 9476.872
Deduct 110 from 150 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.

Advancing to step 10:
55 goes into 400 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 9476.8727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
When dividing 150 by 55, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 9476.87272
Subtracting 110 from 150 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.

Advancing to step 12:
When dividing 400 by 55, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 9476.872727
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
If we divide 150 by 55, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 9476.8727272
Deduct 110 from 150 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.

Let's proceed to step 14:
When dividing 400 by 55, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 9476.87272727
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 9476.87272727 with a remainder of 1.5e-08.
