We're dividing 16221389 by 559 
We're looking to find how many times 559 goes into 16221389.

Step 1:
The number 559 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 559

Let's proceed to step 2:
559 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 559

On to step 3:
When dividing 162 by 559, we get 0 with a remainder of 162.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 162, we get 162.
Fetch the next digit (2) from the dividend, attach it to 162 and continue: 1622 / 559

On to step 4:
When dividing 1622 by 559, we get 2 with a remainder of 504.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1118 from 1622 and we're left with 504.
Fetch the next digit (1) from the dividend, attach it to 504 and continue: 5041 / 559

On to step 5:
The number 559 fits into 5041 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 5031 from 5041, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 559

Moving on to step 6:
103 divided by 559 is 0 with a remainder of 103.
Use 0 as the next digit of our solution. 
Result so far: 290.0
If we take 0 away from 103, we end up with 103.
Fetch the next digit (8) from the dividend, attach it to 103 and continue: 1038 / 559

Moving on to step 7:
When dividing 1038 by 559, we get 1 with a remainder of 479.
Put 1 as the next digit of the answer. 
Result so far: 2901.0
If we subtract 559 from 1038, we get 479.
Append the next digit (9) from the dividend to 479 and continue with: 4799 / 559

Moving on to step 8:
4799 divided by 559 is 8 with a remainder of 327.
Put 8 as the next digit of the answer. 
Result so far: 29018.0
Subtract 4472 from 4799 to get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 9:
If we divide 3270 by 559, we get 5 and a remainder of 475.
Write down 5 as next digit of the result. 
Result so far: 29018.5
Subtracting 2795 from 3270 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 10:
4750 divided by 559 is 8 with a remainder of 278.
Use 8 as the next digit of our solution. 
Result so far: 29018.58
Subtract 4472 from 4750 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 11:
2780 divided by 559 is 4 with a remainder of 544.
Record the quotient 4 as the next digit in the result. 
Result so far: 29018.584
Subtract 2236 from 2780 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 12:
If we divide 5440 by 559, we get 9 and a remainder of 409.
Record the quotient 9 as the next digit in the result. 
Result so far: 29018.5849
Subtract 5031 from 5440 to get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 13:
If we divide 4090 by 559, we get 7 and a remainder of 177.
The next digit of our result is 7. 
Result so far: 29018.58497
Subtract 3913 from 4090 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 14:
559 can be fit into 1770 3 times, resulting in a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 29018.584973
Subtract 1677 from 1770 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 15:
559 can be fit into 930 1 times, resulting in a remainder of 371.
Write down 1 as next digit of the result. 
Result so far: 29018.5849731
Subtracting 559 from 930 leaves us with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 16:
559 goes into 3710 6 times with a remainder of 356.
The next digit of our result is 6. 
Result so far: 29018.58497316
Subtract 3354 from 3710 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The final result is 29018.58497316 with a remainder of 3.56e-07.
