Let's divide 75231105 by 638
We're looking to find how many times 638 goes into 75231105.

On to step 1:
When dividing 7 by 638, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 638

Advancing to step 2:
The number 638 fits into 75 0 times, leaving a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 638

Moving on to step 3:
752 divided by 638 is 1 with a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 638 from 752 to get 114.
Include the next digit (3) from the dividend after 114, then repeat: 1143 / 638

Going ahead to step 4:
638 can be fit into 1143 1 times, resulting in a remainder of 505.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 638 from 1143 leaves us with 505.
Bring next digit (1) of the dividend behind the 505 and repeat the process: 5051 / 638

Going ahead to step 5:
If we divide 5051 by 638, we get 7 and a remainder of 585.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtracting 4466 from 5051 leaves us with 585.
Take the next digit (1) from the dividend and append it to 585, then repeat: 5851 / 638

Step 6:
638 can be fit into 5851 9 times, resulting in a remainder of 109.
Use 9 as the next digit of our solution. 
Result so far: 1179.0
Deduct 5742 from 5851 and we're left with 109.
Grab the next digit (0) from the dividend, add it to 109, then carry on: 1090 / 638

Let's proceed to step 7:
1090 divided by 638 is 1 with a remainder of 452.
The number 1 becomes the next digit in our result. 
Result so far: 11791.0
If we subtract 638 from 1090, we get 452.
Bring next digit (5) of the dividend behind the 452 and repeat the process: 4525 / 638

Going ahead to step 8:
4525 divided by 638 is 7 with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 117917.0
Subtracting 4466 from 4525 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
When dividing 590 by 638, we get 0 with a remainder of 590.
The next digit of our result is 0. 
Result so far: 117917.0
Subtract 0 from 590 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 10:
5900 divided by 638 is 9 with a remainder of 158.
Put 9 as the next digit of the answer. 
Result so far: 117917.09
If we take 5742 away from 5900, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 11:
When dividing 1580 by 638, we get 2 with a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 117917.092
Subtracting 1276 from 1580 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 12:
The number 638 fits into 3040 4 times, leaving a remainder of 488.
The number 4 becomes the next digit in our result. 
Result so far: 117917.0924
The remainder is 488 after subtracting 2552 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 13:
The number 638 fits into 4880 7 times, leaving a remainder of 414.
The number 7 becomes the next digit in our result. 
Result so far: 117917.09247
Deduct 4466 from 4880 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Let's proceed to step 14:
638 goes into 4140 6 times with a remainder of 312.
The next digit of our result is 6. 
Result so far: 117917.092476
If we take 3828 away from 4140, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 15:
3120 divided by 638 is 4 with a remainder of 568.
Put 4 as the next digit of the answer. 
Result so far: 117917.0924764
The remainder is 568 after subtracting 2552 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 16:
If we divide 5680 by 638, we get 8 and a remainder of 576.
Use 8 as the next digit of our solution. 
Result so far: 117917.09247648
Subtracting 5104 from 5680 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

After the division, we end up with 117917.09247648 and a remainder of 5.76e-07.
