81989702 ÷ 538 
We're looking to find how many times 538 goes into 81989702.

On to 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
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 538

On to step 2:
When dividing 81 by 538, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 538

Advancing to step 3:
The number 538 fits into 819 1 times, leaving a remainder of 281.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 538 from 819 and we're left with 281.
Grab the next digit (8) from the dividend, add it to 281, then carry on: 2818 / 538

Step 4:
The number 538 fits into 2818 5 times, leaving a remainder of 128.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 2690 from 2818 leaves us with 128.
Bring next digit (9) of the dividend behind the 128 and repeat the process: 1289 / 538

Moving on to step 5:
538 goes into 1289 2 times with a remainder of 213.
Write down 2 as next digit of the result. 
Result so far: 152.0
Subtract 1076 from 1289 to get 213.
Append the next digit (7) from the dividend to 213 and continue with: 2137 / 538

Moving on to step 6:
538 can be fit into 2137 3 times, resulting in a remainder of 523.
Write down 3 as next digit of the result. 
Result so far: 1523.0
Subtract 1614 from 2137 to get 523.
Fetch the next digit (0) from the dividend, attach it to 523 and continue: 5230 / 538

Going ahead to step 7:
When dividing 5230 by 538, we get 9 with a remainder of 388.
Write down 9 as next digit of the result. 
Result so far: 15239.0
If we take 4842 away from 5230, we end up with 388.
Take the next digit (2) from the dividend and append it to 388, then repeat: 3882 / 538

Advancing to step 8:
If we divide 3882 by 538, we get 7 and a remainder of 116.
Write down 7 as next digit of the result. 
Result so far: 152397.0
If we subtract 3766 from 3882, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 9:
The number 538 fits into 1160 2 times, leaving a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 152397.2
Deduct 1076 from 1160 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 10:
538 can be fit into 840 1 times, resulting in a remainder of 302.
Put 1 as the next digit of the answer. 
Result so far: 152397.21
Subtract 538 from 840 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 11:
When dividing 3020 by 538, we get 5 with a remainder of 330.
Put 5 as the next digit of the answer. 
Result so far: 152397.215
If we subtract 2690 from 3020, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 12:
When dividing 3300 by 538, we get 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 152397.2156
If we take 3228 away from 3300, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
The number 538 fits into 720 1 times, leaving a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 152397.21561
The remainder is 182 after subtracting 538 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 14:
When dividing 1820 by 538, we get 3 with a remainder of 206.
Put 3 as the next digit of the answer. 
Result so far: 152397.215613
The remainder is 206 after subtracting 1614 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 15:
2060 divided by 538 is 3 with a remainder of 446.
The next digit of our result is 3. 
Result so far: 152397.2156133
The remainder is 446 after subtracting 1614 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

In conclusion, the division gives 152397.2156133 with a balance of 4.46e-06.
