55126042 divided by 749 
Our goal is to divide 55126042 by 749.

Step 1:
The number 749 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 749

Step 2:
The number 749 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 749

Let's proceed to step 3:
When dividing 551 by 749, we get 0 with a remainder of 551.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 551, we get 551.
Grab the next digit (2) from the dividend, add it to 551, then carry on: 5512 / 749

On to step 4:
749 can be fit into 5512 7 times, resulting in a remainder of 269.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 5243 from 5512 leaves us with 269.
Append the next digit (6) from the dividend to 269 and continue with: 2696 / 749

On to step 5:
The number 749 fits into 2696 3 times, leaving a remainder of 449.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 449 after subtracting 2247 from 2696.
Take the next digit (0) from the dividend and append it to 449, then repeat: 4490 / 749

Moving on to step 6:
4490 divided by 749 is 5 with a remainder of 745.
Put 5 as the next digit of the answer. 
Result so far: 735.0
The remainder is 745 after subtracting 3745 from 4490.
Include the next digit (4) from the dividend after 745, then repeat: 7454 / 749

Moving on to step 7:
If we divide 7454 by 749, we get 9 and a remainder of 713.
The next digit of our result is 9. 
Result so far: 7359.0
The remainder is 713 after subtracting 6741 from 7454.
Take the next digit (2) from the dividend and append it to 713, then repeat: 7132 / 749

Let's proceed to step 8:
When dividing 7132 by 749, we get 9 with a remainder of 391.
The next digit of our result is 9. 
Result so far: 73599.0
Subtracting 6741 from 7132 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Going ahead to step 9:
When dividing 3910 by 749, we get 5 with a remainder of 165.
The next digit of our result is 5. 
Result so far: 73599.5
Subtract 3745 from 3910 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 10:
1650 divided by 749 is 2 with a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 73599.52
The remainder is 152 after subtracting 1498 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 11:
When dividing 1520 by 749, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 73599.522
If we subtract 1498 from 1520, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 73599.522 with a remainder of 0.0022.
