21157274 ÷ 568 
We're looking to find how many times 568 goes into 21157274.

Going ahead to step 1:
When dividing 2 by 568, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 568

Let's proceed to step 2:
When dividing 21 by 568, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 568

Let's proceed to step 3:
When dividing 211 by 568, we get 0 with a remainder of 211.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 211, we get 211.
Take the next digit (5) from the dividend and append it to 211, then repeat: 2115 / 568

On to step 4:
When dividing 2115 by 568, we get 3 with a remainder of 411.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1704 from 2115 to get 411.
Append the next digit (7) from the dividend to 411 and continue with: 4117 / 568

On to step 5:
When dividing 4117 by 568, we get 7 with a remainder of 141.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 141 after subtracting 3976 from 4117.
Bring next digit (2) of the dividend behind the 141 and repeat the process: 1412 / 568

Step 6:
If we divide 1412 by 568, we get 2 and a remainder of 276.
Put 2 as the next digit of the answer. 
Result so far: 372.0
Deduct 1136 from 1412 and we're left with 276.
Fetch the next digit (7) from the dividend, attach it to 276 and continue: 2767 / 568

Let's proceed to step 7:
568 can be fit into 2767 4 times, resulting in a remainder of 495.
Put 4 as the next digit of the answer. 
Result so far: 3724.0
If we take 2272 away from 2767, we end up with 495.
Fetch the next digit (4) from the dividend, attach it to 495 and continue: 4954 / 568

Step 8:
4954 divided by 568 is 8 with a remainder of 410.
Put 8 as the next digit of the answer. 
Result so far: 37248.0
Subtracting 4544 from 4954 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 9:
568 goes into 4100 7 times with a remainder of 124.
The next digit of our result is 7. 
Result so far: 37248.7
The remainder is 124 after subtracting 3976 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
1240 divided by 568 is 2 with a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 37248.72
If we take 1136 away from 1240, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 11:
If we divide 1040 by 568, we get 1 and a remainder of 472.
The number 1 becomes the next digit in our result. 
Result so far: 37248.721
If we take 568 away from 1040, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 12:
568 can be fit into 4720 8 times, resulting in a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 37248.7218
If we subtract 4544 from 4720, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 13:
When dividing 1760 by 568, we get 3 with a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 37248.72183
If we take 1704 away from 1760, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
When dividing 560 by 568, we get 0 with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 37248.72183
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 15:
5600 divided by 568 is 9 with a remainder of 488.
Record the quotient 9 as the next digit in the result. 
Result so far: 37248.7218309
Deduct 5112 from 5600 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 16:
The number 568 fits into 4880 8 times, leaving a remainder of 336.
The number 8 becomes the next digit in our result. 
Result so far: 37248.72183098
If we subtract 4544 from 4880, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

After the division, we end up with 37248.72183098 and a remainder of 3.36e-07.
