We're dividing 20811980 by 557 
Let's see how many times 557 fits into 20811980.

On to step 1:
557 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 557

Let's proceed to step 2:
The number 557 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 557

Going ahead to step 3:
The number 557 fits into 208 0 times, leaving a remainder of 208.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 208 and we're left with 208.
Bring next digit (1) of the dividend behind the 208 and repeat the process: 2081 / 557

Going ahead to step 4:
If we divide 2081 by 557, we get 3 and a remainder of 410.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 410 after subtracting 1671 from 2081.
Take the next digit (1) from the dividend and append it to 410, then repeat: 4101 / 557

Going ahead to step 5:
The number 557 fits into 4101 7 times, leaving a remainder of 202.
Put 7 as the next digit of the answer. 
Result so far: 37.0
The remainder is 202 after subtracting 3899 from 4101.
Grab the next digit (9) from the dividend, add it to 202, then carry on: 2029 / 557

On to step 6:
557 goes into 2029 3 times with a remainder of 358.
The number 3 becomes the next digit in our result. 
Result so far: 373.0
Subtracting 1671 from 2029 leaves us with 358.
Grab the next digit (8) from the dividend, add it to 358, then carry on: 3588 / 557

On to step 7:
3588 divided by 557 is 6 with a remainder of 246.
The number 6 becomes the next digit in our result. 
Result so far: 3736.0
If we take 3342 away from 3588, we end up with 246.
Take the next digit (0) from the dividend and append it to 246, then repeat: 2460 / 557

Step 8:
557 can be fit into 2460 4 times, resulting in a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 37364.0
Subtracting 2228 from 2460 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 9:
If we divide 2320 by 557, we get 4 and a remainder of 92.
Put 4 as the next digit of the answer. 
Result so far: 37364.4
If we subtract 2228 from 2320, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 10:
557 can be fit into 920 1 times, resulting in a remainder of 363.
The number 1 becomes the next digit in our result. 
Result so far: 37364.41
If we take 557 away from 920, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Let's proceed to step 11:
557 can be fit into 3630 6 times, resulting in a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 37364.416
If we take 3342 away from 3630, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 12:
557 can be fit into 2880 5 times, resulting in a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 37364.4165
Subtract 2785 from 2880 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.

Moving on to step 13:
When dividing 950 by 557, we get 1 with a remainder of 393.
Put 1 as the next digit of the answer. 
Result so far: 37364.41651
Deduct 557 from 950 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 14:
The number 557 fits into 3930 7 times, leaving a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 37364.416517
If we take 3899 away from 3930, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 15:
The number 557 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 37364.416517
If we subtract 0 from 310, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 16:
3100 divided by 557 is 5 with a remainder of 315.
The next digit of our result is 5. 
Result so far: 37364.41651705
Deduct 2785 from 3100 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

After the division, we end up with 37364.41651705 and a remainder of 3.15e-07.
