55573285 ÷ 221 
Our goal is to divide 55573285 by 221.

Step 1:
If we divide 5 by 221, 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.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 221

On to step 2:
The number 221 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 221

Going ahead to step 3:
221 can be fit into 555 2 times, resulting in a remainder of 113.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 442 from 555, we get 113.
Bring next digit (7) of the dividend behind the 113 and repeat the process: 1137 / 221

Moving on to step 4:
221 can be fit into 1137 5 times, resulting in a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 1105 from 1137 and we're left with 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 221

Going ahead to step 5:
If we divide 323 by 221, we get 1 and a remainder of 102.
The next digit of our result is 1. 
Result so far: 251.0
Subtracting 221 from 323 leaves us with 102.
Fetch the next digit (2) from the dividend, attach it to 102 and continue: 1022 / 221

Moving on to step 6:
If we divide 1022 by 221, we get 4 and a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 2514.0
Subtracting 884 from 1022 leaves us with 138.
Include the next digit (8) from the dividend after 138, then repeat: 1388 / 221

Step 7:
221 can be fit into 1388 6 times, resulting in a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 25146.0
If we take 1326 away from 1388, we end up with 62.
Take the next digit (5) from the dividend and append it to 62, then repeat: 625 / 221

Advancing to step 8:
625 divided by 221 is 2 with a remainder of 183.
The number 2 becomes the next digit in our result. 
Result so far: 251462.0
Subtracting 442 from 625 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 9:
When dividing 1830 by 221, we get 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 251462.8
Subtracting 1768 from 1830 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
221 goes into 620 2 times with a remainder of 178.
The number 2 becomes the next digit in our result. 
Result so far: 251462.82
Subtract 442 from 620 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 11:
221 can be fit into 1780 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 251462.828
If we subtract 1768 from 1780, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
221 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 251462.828
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 13:
If we divide 1200 by 221, we get 5 and a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 251462.82805
Subtracting 1105 from 1200 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 14:
When dividing 950 by 221, we get 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 251462.828054
If we take 884 away from 950, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 15:
660 divided by 221 is 2 with a remainder of 218.
Put 2 as the next digit of the answer. 
Result so far: 251462.8280542
Subtract 442 from 660 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 16:
If we divide 2180 by 221, we get 9 and a remainder of 191.
Record the quotient 9 as the next digit in the result. 
Result so far: 251462.82805429
If we subtract 1989 from 2180, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

In conclusion, the division gives 251462.82805429 with a balance of 1.91e-07.
