Let's divide 21289749 by 557
Let's see how many times 557 fits into 21289749.

Let's proceed to step 1:
If we divide 2 by 557, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 557

Advancing to step 2:
The number 557 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 557

On to step 3:
When dividing 212 by 557, we get 0 with a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Grab the next digit (8) from the dividend, add it to 212, then carry on: 2128 / 557

Moving on to step 4:
2128 divided by 557 is 3 with a remainder of 457.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1671 from 2128 and we're left with 457.
Fetch the next digit (9) from the dividend, attach it to 457 and continue: 4579 / 557

Advancing to step 5:
If we divide 4579 by 557, we get 8 and a remainder of 123.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 4456 from 4579 to get 123.
Grab the next digit (7) from the dividend, add it to 123, then carry on: 1237 / 557

Advancing to step 6:
557 can be fit into 1237 2 times, resulting in a remainder of 123.
The next digit of our result is 2. 
Result so far: 382.0
If we subtract 1114 from 1237, we get 123.
Include the next digit (4) from the dividend after 123, then repeat: 1234 / 557

Let's proceed to step 7:
If we divide 1234 by 557, we get 2 and a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 3822.0
The remainder is 120 after subtracting 1114 from 1234.
Include the next digit (9) from the dividend after 120, then repeat: 1209 / 557

On to step 8:
557 goes into 1209 2 times with a remainder of 95.
The next digit of our result is 2. 
Result so far: 38222.0
Subtract 1114 from 1209 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 9:
The number 557 fits into 950 1 times, leaving a remainder of 393.
Use 1 as the next digit of our solution. 
Result so far: 38222.1
If we subtract 557 from 950, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Let's proceed to step 10:
When dividing 3930 by 557, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 38222.17
Subtract 3899 from 3930 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
557 goes into 310 0 times with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 38222.17
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 12:
3100 divided by 557 is 5 with a remainder of 315.
The next digit of our result is 5. 
Result so far: 38222.1705
If we subtract 2785 from 3100, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 13:
3150 divided by 557 is 5 with a remainder of 365.
The next digit of our result is 5. 
Result so far: 38222.17055
Subtracting 2785 from 3150 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

The final outcome is 38222.17055, with a leftover of 0.000365.
