75715165 ÷ 544 
We want to figure out the number of times 75715165 can be divided by 544.

Step 1:
When dividing 7 by 544, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 544

Advancing to step 2:
75 divided by 544 is 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Include the next digit (7) from the dividend after 75, then repeat: 757 / 544

Let's proceed to step 3:
When dividing 757 by 544, we get 1 with a remainder of 213.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 544 from 757 and we're left with 213.
Include the next digit (1) from the dividend after 213, then repeat: 2131 / 544

Moving on to step 4:
When dividing 2131 by 544, we get 3 with a remainder of 499.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1632 from 2131, we get 499.
Grab the next digit (5) from the dividend, add it to 499, then carry on: 4995 / 544

Going ahead to step 5:
If we divide 4995 by 544, we get 9 and a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Subtract 4896 from 4995 to get 99.
Take the next digit (1) from the dividend and append it to 99, then repeat: 991 / 544

Advancing to step 6:
The number 544 fits into 991 1 times, leaving a remainder of 447.
Record the quotient 1 as the next digit in the result. 
Result so far: 1391.0
The remainder is 447 after subtracting 544 from 991.
Grab the next digit (6) from the dividend, add it to 447, then carry on: 4476 / 544

Going ahead to step 7:
If we divide 4476 by 544, we get 8 and a remainder of 124.
Use 8 as the next digit of our solution. 
Result so far: 13918.0
The remainder is 124 after subtracting 4352 from 4476.
Bring next digit (5) of the dividend behind the 124 and repeat the process: 1245 / 544

Step 8:
1245 divided by 544 is 2 with a remainder of 157.
The next digit of our result is 2. 
Result so far: 139182.0
Deduct 1088 from 1245 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 9:
1570 divided by 544 is 2 with a remainder of 482.
The next digit of our result is 2. 
Result so far: 139182.2
Deduct 1088 from 1570 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 10:
544 can be fit into 4820 8 times, resulting in a remainder of 468.
Use 8 as the next digit of our solution. 
Result so far: 139182.28
Deduct 4352 from 4820 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 11:
The number 544 fits into 4680 8 times, leaving a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 139182.288
Subtract 4352 from 4680 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Our division results in 139182.288 with a remaining 0.0328.
