We're dividing 15638811 by 749 
Our goal is to divide 15638811 by 749.

Let's proceed to step 1:
When dividing 1 by 749, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 749

Step 2:
749 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 749

Going ahead to step 3:
156 divided by 749 is 0 with a remainder of 156.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 156 and we're left with 156.
Append the next digit (3) from the dividend to 156 and continue with: 1563 / 749

Advancing to step 4:
749 goes into 1563 2 times with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1498 away from 1563, we end up with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 749

Moving on to step 5:
749 goes into 658 0 times with a remainder of 658.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 658, we get 658.
Fetch the next digit (8) from the dividend, attach it to 658 and continue: 6588 / 749

Let's proceed to step 6:
If we divide 6588 by 749, we get 8 and a remainder of 596.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
If we take 5992 away from 6588, we end up with 596.
Bring next digit (1) of the dividend behind the 596 and repeat the process: 5961 / 749

Moving on to step 7:
5961 divided by 749 is 7 with a remainder of 718.
Record the quotient 7 as the next digit in the result. 
Result so far: 2087.0
If we subtract 5243 from 5961, we get 718.
Append the next digit (1) from the dividend to 718 and continue with: 7181 / 749

Moving on to step 8:
7181 divided by 749 is 9 with a remainder of 440.
The number 9 becomes the next digit in our result. 
Result so far: 20879.0
If we subtract 6741 from 7181, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 9:
749 goes into 4400 5 times with a remainder of 655.
Use 5 as the next digit of our solution. 
Result so far: 20879.5
Deduct 3745 from 4400 and we're left with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Going ahead to step 10:
The number 749 fits into 6550 8 times, leaving a remainder of 558.
The next digit of our result is 8. 
Result so far: 20879.58
If we take 5992 away from 6550, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 11:
749 goes into 5580 7 times with a remainder of 337.
Use 7 as the next digit of our solution. 
Result so far: 20879.587
The remainder is 337 after subtracting 5243 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 12:
3370 divided by 749 is 4 with a remainder of 374.
Put 4 as the next digit of the answer. 
Result so far: 20879.5874
The remainder is 374 after subtracting 2996 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 13:
The number 749 fits into 3740 4 times, leaving a remainder of 744.
Use 4 as the next digit of our solution. 
Result so far: 20879.58744
Subtracting 2996 from 3740 leaves us with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

After the division, we end up with 20879.58744 and a remainder of 0.000744.
