Let's divide 53975721 by 221
Our goal is to divide 53975721 by 221.

On to step 1:
221 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 221

On to step 2:
221 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 221

Let's proceed to step 3:
The number 221 fits into 539 2 times, leaving a remainder of 97.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 442 from 539 leaves us with 97.
Grab the next digit (7) from the dividend, add it to 97, then carry on: 977 / 221

Advancing to step 4:
If we divide 977 by 221, we get 4 and a remainder of 93.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 884 from 977 and we're left with 93.
Append the next digit (5) from the dividend to 93 and continue with: 935 / 221

On to step 5:
221 can be fit into 935 4 times, resulting in a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 244.0
Deduct 884 from 935 and we're left with 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 221

Let's proceed to step 6:
When dividing 517 by 221, we get 2 with a remainder of 75.
The next digit of our result is 2. 
Result so far: 2442.0
If we take 442 away from 517, we end up with 75.
Append the next digit (2) from the dividend to 75 and continue with: 752 / 221

Moving on to step 7:
When dividing 752 by 221, we get 3 with a remainder of 89.
Record the quotient 3 as the next digit in the result. 
Result so far: 24423.0
If we take 663 away from 752, we end up with 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 221

Moving on to step 8:
When dividing 891 by 221, we get 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 244234.0
If we take 884 away from 891, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
The number 221 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 244234.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
If we divide 700 by 221, we get 3 and a remainder of 37.
The next digit of our result is 3. 
Result so far: 244234.03
Deduct 663 from 700 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 11:
221 goes into 370 1 times with a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 244234.031
Subtracting 221 from 370 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 12:
221 can be fit into 1490 6 times, resulting in a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 244234.0316
Subtract 1326 from 1490 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 13:
When dividing 1640 by 221, we get 7 with a remainder of 93.
Use 7 as the next digit of our solution. 
Result so far: 244234.03167
Deduct 1547 from 1640 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 14:
The number 221 fits into 930 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 244234.031674
Deduct 884 from 930 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 15:
The number 221 fits into 460 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 244234.0316742
Subtract 442 from 460 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 16:
When dividing 180 by 221, we get 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 244234.0316742
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

In conclusion, the division gives 244234.0316742 with a balance of 1.8e-07.
