Let's divide 81102319 by 538
We want to divide 81102319 by 538.

Step 1:
When dividing 8 by 538, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 538

Going ahead to step 2:
81 divided by 538 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 538

Moving on to step 3:
811 divided by 538 is 1 with a remainder of 273.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 538 from 811 and we're left with 273.
Append the next digit (0) from the dividend to 273 and continue with: 2730 / 538

Going ahead to step 4:
538 goes into 2730 5 times with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 40 after subtracting 2690 from 2730.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 538

Step 5:
When dividing 402 by 538, we get 0 with a remainder of 402.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Deduct 0 from 402 and we're left with 402.
Take the next digit (3) from the dividend and append it to 402, then repeat: 4023 / 538

Going ahead to step 6:
538 goes into 4023 7 times with a remainder of 257.
The next digit of our result is 7. 
Result so far: 1507.0
Deduct 3766 from 4023 and we're left with 257.
Include the next digit (1) from the dividend after 257, then repeat: 2571 / 538

Step 7:
If we divide 2571 by 538, we get 4 and a remainder of 419.
The number 4 becomes the next digit in our result. 
Result so far: 15074.0
If we take 2152 away from 2571, we end up with 419.
Append the next digit (9) from the dividend to 419 and continue with: 4199 / 538

Let's proceed to step 8:
538 can be fit into 4199 7 times, resulting in a remainder of 433.
The next digit of our result is 7. 
Result so far: 150747.0
Subtract 3766 from 4199 to get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 9:
The number 538 fits into 4330 8 times, leaving a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 150747.8
If we subtract 4304 from 4330, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
When dividing 260 by 538, we get 0 with a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 150747.8
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
538 can be fit into 2600 4 times, resulting in a remainder of 448.
Write down 4 as next digit of the result. 
Result so far: 150747.804
Subtract 2152 from 2600 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 12:
538 goes into 4480 8 times with a remainder of 176.
Put 8 as the next digit of the answer. 
Result so far: 150747.8048
The remainder is 176 after subtracting 4304 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 13:
1760 divided by 538 is 3 with a remainder of 146.
Use 3 as the next digit of our solution. 
Result so far: 150747.80483
The remainder is 146 after subtracting 1614 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 14:
538 goes into 1460 2 times with a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 150747.804832
Subtracting 1076 from 1460 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 15:
538 goes into 3840 7 times with a remainder of 74.
The next digit of our result is 7. 
Result so far: 150747.8048327
Deduct 3766 from 3840 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 16:
The number 538 fits into 740 1 times, leaving a remainder of 202.
The number 1 becomes the next digit in our result. 
Result so far: 150747.80483271
If we subtract 538 from 740, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Our division results in 150747.80483271 with a remaining 2.02e-07.
