We're dividing 71544061 by 638 
We want to divide 71544061 by 638.

Going ahead to step 1:
If we divide 7 by 638, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 638

Going ahead to step 2:
When dividing 71 by 638, we get 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 638

Moving on to step 3:
638 goes into 715 1 times with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 638 from 715 leaves us with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 638

On to step 4:
The number 638 fits into 774 1 times, leaving a remainder of 136.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 638 from 774 to get 136.
Grab the next digit (4) from the dividend, add it to 136, then carry on: 1364 / 638

Advancing to step 5:
When dividing 1364 by 638, we get 2 with a remainder of 88.
The next digit of our result is 2. 
Result so far: 112.0
Subtract 1276 from 1364 to get 88.
Bring next digit (0) of the dividend behind the 88 and repeat the process: 880 / 638

On to step 6:
880 divided by 638 is 1 with a remainder of 242.
Record the quotient 1 as the next digit in the result. 
Result so far: 1121.0
Subtracting 638 from 880 leaves us with 242.
Append the next digit (6) from the dividend to 242 and continue with: 2426 / 638

Step 7:
638 goes into 2426 3 times with a remainder of 512.
Put 3 as the next digit of the answer. 
Result so far: 11213.0
Subtract 1914 from 2426 to get 512.
Append the next digit (1) from the dividend to 512 and continue with: 5121 / 638

Step 8:
638 goes into 5121 8 times with a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 112138.0
Subtract 5104 from 5121 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
When dividing 170 by 638, we get 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 112138.0
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 10:
If we divide 1700 by 638, we get 2 and a remainder of 424.
The number 2 becomes the next digit in our result. 
Result so far: 112138.02
Deduct 1276 from 1700 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 11:
The number 638 fits into 4240 6 times, leaving a remainder of 412.
The next digit of our result is 6. 
Result so far: 112138.026
Subtracting 3828 from 4240 leaves us 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.

Let's proceed to step 12:
4120 divided by 638 is 6 with a remainder of 292.
Use 6 as the next digit of our solution. 
Result so far: 112138.0266
Subtracting 3828 from 4120 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The final result is 112138.0266 with a remainder of 0.00292.
