75428128 ÷ 909 
We want to figure out the number of times 75428128 can be divided by 909.

Let's proceed to step 1:
If we divide 7 by 909, we get 0 and 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.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 909

Moving on to step 2:
909 can be fit into 75 0 times, resulting in 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.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 909

Advancing to step 3:
754 divided by 909 is 0 with a remainder of 754.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 754 leaves us with 754.
Include the next digit (2) from the dividend after 754, then repeat: 7542 / 909

Advancing to step 4:
909 goes into 7542 8 times with a remainder of 270.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7272 from 7542 leaves us with 270.
Append the next digit (8) from the dividend to 270 and continue with: 2708 / 909

Advancing to step 5:
If we divide 2708 by 909, we get 2 and a remainder of 890.
Use 2 as the next digit of our solution. 
Result so far: 82.0
If we subtract 1818 from 2708, we get 890.
Fetch the next digit (1) from the dividend, attach it to 890 and continue: 8901 / 909

On to step 6:
909 can be fit into 8901 9 times, resulting in a remainder of 720.
Record the quotient 9 as the next digit in the result. 
Result so far: 829.0
Subtracting 8181 from 8901 leaves us with 720.
Grab the next digit (2) from the dividend, add it to 720, then carry on: 7202 / 909

Advancing to step 7:
7202 divided by 909 is 7 with a remainder of 839.
Record the quotient 7 as the next digit in the result. 
Result so far: 8297.0
Deduct 6363 from 7202 and we're left with 839.
Grab the next digit (8) from the dividend, add it to 839, then carry on: 8398 / 909

On to step 8:
The number 909 fits into 8398 9 times, leaving a remainder of 217.
Put 9 as the next digit of the answer. 
Result so far: 82979.0
Subtracting 8181 from 8398 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 9:
When dividing 2170 by 909, we get 2 with a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 82979.2
If we subtract 1818 from 2170, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 10:
3520 divided by 909 is 3 with a remainder of 793.
Use 3 as the next digit of our solution. 
Result so far: 82979.23
The remainder is 793 after subtracting 2727 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Let's proceed to step 11:
When dividing 7930 by 909, we get 8 with a remainder of 658.
Put 8 as the next digit of the answer. 
Result so far: 82979.238
The remainder is 658 after subtracting 7272 from 7930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

On to step 12:
When dividing 6580 by 909, we get 7 with a remainder of 217.
The number 7 becomes the next digit in our result. 
Result so far: 82979.2387
Subtract 6363 from 6580 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 13:
If we divide 2170 by 909, we get 2 and a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 82979.23872
The remainder is 352 after subtracting 1818 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 14:
The number 909 fits into 3520 3 times, leaving a remainder of 793.
Use 3 as the next digit of our solution. 
Result so far: 82979.238723
If we take 2727 away from 3520, we end up with 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Advancing to step 15:
909 goes into 7930 8 times with a remainder of 658.
Use 8 as the next digit of our solution. 
Result so far: 82979.2387238
If we take 7272 away from 7930, we end up with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Advancing to step 16:
909 can be fit into 6580 7 times, resulting in a remainder of 217.
The number 7 becomes the next digit in our result. 
Result so far: 82979.23872387
Deduct 6363 from 6580 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

In conclusion, the division gives 82979.23872387 with a balance of 2.17e-07.
