We divide 42558438 by 242
We want to figure out the number of times 42558438 can be divided by 242.

Step 1:
If we divide 4 by 242, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 242

Step 2:
242 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 242

Going ahead to step 3:
425 divided by 242 is 1 with a remainder of 183.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 242 from 425 leaves us with 183.
Include the next digit (5) from the dividend after 183, then repeat: 1835 / 242

Advancing to step 4:
The number 242 fits into 1835 7 times, leaving a remainder of 141.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 1694 from 1835 leaves us with 141.
Include the next digit (8) from the dividend after 141, then repeat: 1418 / 242

Going ahead to step 5:
The number 242 fits into 1418 5 times, leaving a remainder of 208.
Write down 5 as next digit of the result. 
Result so far: 175.0
Subtract 1210 from 1418 to get 208.
Include the next digit (4) from the dividend after 208, then repeat: 2084 / 242

Advancing to step 6:
The number 242 fits into 2084 8 times, leaving a remainder of 148.
The next digit of our result is 8. 
Result so far: 1758.0
Deduct 1936 from 2084 and we're left with 148.
Fetch the next digit (3) from the dividend, attach it to 148 and continue: 1483 / 242

Step 7:
1483 divided by 242 is 6 with a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 17586.0
Deduct 1452 from 1483 and we're left with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 242

Advancing to step 8:
The number 242 fits into 318 1 times, leaving a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 175861.0
Subtract 242 from 318 to get 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 9:
242 can be fit into 760 3 times, resulting in a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 175861.3
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.

Moving on to step 10:
The number 242 fits into 340 1 times, leaving a remainder of 98.
The next digit of our result is 1. 
Result so far: 175861.31
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.

Step 11:
980 divided by 242 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 175861.314
If we subtract 968 from 980, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
242 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 175861.314
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
If we divide 1200 by 242, we get 4 and a remainder of 232.
Use 4 as the next digit of our solution. 
Result so far: 175861.31404
The remainder is 232 after subtracting 968 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 14:
242 can be fit into 2320 9 times, resulting in a remainder of 142.
Put 9 as the next digit of the answer. 
Result so far: 175861.314049
If we subtract 2178 from 2320, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 15:
242 goes into 1420 5 times with a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 175861.3140495
If we take 1210 away from 1420, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 16:
The number 242 fits into 2100 8 times, leaving a remainder of 164.
The number 8 becomes the next digit in our result. 
Result so far: 175861.31404958
The remainder is 164 after subtracting 1936 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The quotient of the division is 175861.31404958, and the remainder is 1.64e-07.
