31555782 divided by 749 
We want to figure out the number of times 31555782 can be divided by 749.

Step 1:
749 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 749

Going ahead to step 2:
If we divide 31 by 749, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 749

Let's proceed to step 3:
When dividing 315 by 749, we get 0 with a remainder of 315.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 315, we end up with 315.
Take the next digit (5) from the dividend and append it to 315, then repeat: 3155 / 749

Going ahead to step 4:
The number 749 fits into 3155 4 times, leaving a remainder of 159.
The next digit of our result is 4. 
Result so far: 4.0
If we take 2996 away from 3155, we end up with 159.
Include the next digit (5) from the dividend after 159, then repeat: 1595 / 749

Going ahead to step 5:
When dividing 1595 by 749, we get 2 with a remainder of 97.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 1498 from 1595, we get 97.
Grab the next digit (7) from the dividend, add it to 97, then carry on: 977 / 749

Going ahead to step 6:
749 goes into 977 1 times with a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
If we subtract 749 from 977, we get 228.
Fetch the next digit (8) from the dividend, attach it to 228 and continue: 2288 / 749

Advancing to step 7:
When dividing 2288 by 749, we get 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 4213.0
If we subtract 2247 from 2288, we get 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 749

Moving on to step 8:
749 goes into 412 0 times with a remainder of 412.
Record the quotient 0 as the next digit in the result. 
Result so far: 42130.0
Deduct 0 from 412 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 9:
4120 divided by 749 is 5 with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 42130.5
If we subtract 3745 from 4120, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 10:
749 goes into 3750 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 42130.55
If we subtract 3745 from 3750, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 42130.55, with a leftover of 0.005.
