Let's divide 64176486 by 221
Our goal is to divide 64176486 by 221.

Let's proceed to step 1:
If we divide 6 by 221, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 221

Going ahead to step 2:
If we divide 64 by 221, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 221

Let's proceed to step 3:
221 goes into 641 2 times with a remainder of 199.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 199 after subtracting 442 from 641.
Include the next digit (7) from the dividend after 199, then repeat: 1997 / 221

Moving on to step 4:
When dividing 1997 by 221, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 1989 from 1997, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 221

On to step 5:
If we divide 86 by 221, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 290.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 221

On to step 6:
When dividing 864 by 221, we get 3 with a remainder of 201.
Put 3 as the next digit of the answer. 
Result so far: 2903.0
If we subtract 663 from 864, we get 201.
Fetch the next digit (8) from the dividend, attach it to 201 and continue: 2018 / 221

Step 7:
2018 divided by 221 is 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 29039.0
Subtracting 1989 from 2018 leaves us with 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 221

Step 8:
296 divided by 221 is 1 with a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 290391.0
The remainder is 75 after subtracting 221 from 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
When dividing 750 by 221, we get 3 with a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 290391.3
If we take 663 away from 750, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 10:
870 divided by 221 is 3 with a remainder of 207.
Write down 3 as next digit of the result. 
Result so far: 290391.33
Subtract 663 from 870 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

The final result is 290391.33 with a remainder of 0.207.
