82161320 divided by 538 
We want to figure out the number of times 82161320 can be divided by 538.

Step 1:
538 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 538

Let's proceed to step 2:
If we divide 82 by 538, we get 0 and a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 538

Step 3:
538 can be fit into 821 1 times, resulting in a remainder of 283.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 538 from 821 and we're left with 283.
Include the next digit (6) from the dividend after 283, then repeat: 2836 / 538

Let's proceed to step 4:
538 goes into 2836 5 times with a remainder of 146.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 2690 from 2836, we get 146.
Fetch the next digit (1) from the dividend, attach it to 146 and continue: 1461 / 538

Advancing to step 5:
The number 538 fits into 1461 2 times, leaving a remainder of 385.
Write down 2 as next digit of the result. 
Result so far: 152.0
Deduct 1076 from 1461 and we're left with 385.
Take the next digit (3) from the dividend and append it to 385, then repeat: 3853 / 538

Going ahead to step 6:
The number 538 fits into 3853 7 times, leaving a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 1527.0
Subtract 3766 from 3853 to get 87.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 538

Advancing to step 7:
The number 538 fits into 872 1 times, leaving a remainder of 334.
Put 1 as the next digit of the answer. 
Result so far: 15271.0
The remainder is 334 after subtracting 538 from 872.
Grab the next digit (0) from the dividend, add it to 334, then carry on: 3340 / 538

Going ahead to step 8:
538 can be fit into 3340 6 times, resulting in a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 152716.0
Subtract 3228 from 3340 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 9:
When dividing 1120 by 538, we get 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 152716.2
Subtract 1076 from 1120 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
538 goes into 440 0 times with a remainder of 440.
The next digit of our result is 0. 
Result so far: 152716.2
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 11:
The number 538 fits into 4400 8 times, leaving a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 152716.208
Subtracting 4304 from 4400 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
If we divide 960 by 538, we get 1 and a remainder of 422.
Use 1 as the next digit of our solution. 
Result so far: 152716.2081
Subtracting 538 from 960 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 13:
When dividing 4220 by 538, we get 7 with a remainder of 454.
Record the quotient 7 as the next digit in the result. 
Result so far: 152716.20817
If we take 3766 away from 4220, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 14:
538 can be fit into 4540 8 times, resulting in a remainder of 236.
The next digit of our result is 8. 
Result so far: 152716.208178
Subtract 4304 from 4540 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 15:
The number 538 fits into 2360 4 times, leaving a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 152716.2081784
The remainder is 208 after subtracting 2152 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 16:
When dividing 2080 by 538, we get 3 with a remainder of 466.
The number 3 becomes the next digit in our result. 
Result so far: 152716.20817843
If we subtract 1614 from 2080, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Our division results in 152716.20817843 with a remaining 4.66e-07.
