We look at the division of 81197244 by 539 
We want to divide 81197244 by 539.

Step 1:
When dividing 8 by 539, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 539

Moving on to step 2:
When dividing 81 by 539, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 539

Let's proceed to step 3:
When dividing 811 by 539, we get 1 with a remainder of 272.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 272 after subtracting 539 from 811.
Grab the next digit (9) from the dividend, add it to 272, then carry on: 2729 / 539

Moving on to step 4:
If we divide 2729 by 539, we get 5 and a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2695 from 2729 to get 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 539

Going ahead to step 5:
The number 539 fits into 347 0 times, leaving a remainder of 347.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Subtract 0 from 347 to get 347.
Bring next digit (2) of the dividend behind the 347 and repeat the process: 3472 / 539

Step 6:
539 goes into 3472 6 times with a remainder of 238.
Use 6 as the next digit of our solution. 
Result so far: 1506.0
Subtract 3234 from 3472 to get 238.
Grab the next digit (4) from the dividend, add it to 238, then carry on: 2384 / 539

Advancing to step 7:
2384 divided by 539 is 4 with a remainder of 228.
Put 4 as the next digit of the answer. 
Result so far: 15064.0
The remainder is 228 after subtracting 2156 from 2384.
Bring next digit (4) of the dividend behind the 228 and repeat the process: 2284 / 539

Step 8:
539 can be fit into 2284 4 times, resulting in a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 150644.0
Subtract 2156 from 2284 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 9:
539 can be fit into 1280 2 times, resulting in a remainder of 202.
Record the quotient 2 as the next digit in the result. 
Result so far: 150644.2
Deduct 1078 from 1280 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 10:
2020 divided by 539 is 3 with a remainder of 403.
Record the quotient 3 as the next digit in the result. 
Result so far: 150644.23
If we take 1617 away from 2020, we end up with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Let's proceed to step 11:
539 can be fit into 4030 7 times, resulting in a remainder of 257.
Write down 7 as next digit of the result. 
Result so far: 150644.237
The remainder is 257 after subtracting 3773 from 4030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 12:
The number 539 fits into 2570 4 times, leaving a remainder of 414.
The number 4 becomes the next digit in our result. 
Result so far: 150644.2374
If we take 2156 away from 2570, we end up 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.

Going ahead to step 13:
The number 539 fits into 4140 7 times, leaving a remainder of 367.
Put 7 as the next digit of the answer. 
Result so far: 150644.23747
If we take 3773 away from 4140, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Moving on to step 14:
3670 divided by 539 is 6 with a remainder of 436.
Put 6 as the next digit of the answer. 
Result so far: 150644.237476
Deduct 3234 from 3670 and we're left with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Going ahead to step 15:
4360 divided by 539 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 150644.2374768
Subtract 4312 from 4360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 16:
539 goes into 480 0 times with a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 150644.2374768
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

After the division, we end up with 150644.2374768 and a remainder of 4.8e-07.
