20643745 ÷ 242 
We're looking to find how many times 242 goes into 20643745.

Going ahead to step 1:
The number 242 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 242

Moving on to step 2:
242 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 242

Step 3:
242 can be fit into 206 0 times, resulting in a remainder of 206.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 206, we end up with 206.
Bring next digit (4) of the dividend behind the 206 and repeat the process: 2064 / 242

On to step 4:
2064 divided by 242 is 8 with a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 1936 from 2064 to get 128.
Take the next digit (3) from the dividend and append it to 128, then repeat: 1283 / 242

Let's proceed to step 5:
When dividing 1283 by 242, we get 5 with a remainder of 73.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Deduct 1210 from 1283 and we're left with 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 242

Moving on to step 6:
When dividing 737 by 242, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 853.0
If we take 726 away from 737, we end up with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 242

Going ahead to step 7:
When dividing 114 by 242, we get 0 with a remainder of 114.
Record the quotient 0 as the next digit in the result. 
Result so far: 8530.0
If we take 0 away from 114, we end up with 114.
Fetch the next digit (5) from the dividend, attach it to 114 and continue: 1145 / 242

Moving on to step 8:
If we divide 1145 by 242, we get 4 and a remainder of 177.
Record the quotient 4 as the next digit in the result. 
Result so far: 85304.0
Deduct 968 from 1145 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 9:
1770 divided by 242 is 7 with a remainder of 76.
Use 7 as the next digit of our solution. 
Result so far: 85304.7
Subtracting 1694 from 1770 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
242 goes into 760 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 85304.73
Subtracting 726 from 760 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
242 goes into 340 1 times with a remainder of 98.
Write down 1 as next digit of the result. 
Result so far: 85304.731
Deduct 242 from 340 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 12:
When dividing 980 by 242, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 85304.7314
The remainder is 12 after subtracting 968 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
242 goes into 120 0 times with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 85304.7314
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 14:
The number 242 fits into 1200 4 times, leaving a remainder of 232.
Write down 4 as next digit of the result. 
Result so far: 85304.731404
If we take 968 away from 1200, we end up 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.

On to step 15:
If we divide 2320 by 242, we get 9 and a remainder of 142.
The number 9 becomes the next digit in our result. 
Result so far: 85304.7314049
Deduct 2178 from 2320 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 16:
If we divide 1420 by 242, we get 5 and a remainder of 210.
The next digit of our result is 5. 
Result so far: 85304.73140495
If we subtract 1210 from 1420, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 85304.73140495, with a leftover of 2.1e-07.
