81027371 ÷ 523 
We want to divide 81027371 by 523.

Let's proceed to step 1:
If we divide 8 by 523, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 523

Step 2:
The number 523 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 523

Advancing to step 3:
If we divide 810 by 523, we get 1 and a remainder of 287.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 523 from 810 and we're left with 287.
Append the next digit (2) from the dividend to 287 and continue with: 2872 / 523

On to step 4:
When dividing 2872 by 523, we get 5 with a remainder of 257.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2615 away from 2872, we end up with 257.
Append the next digit (7) from the dividend to 257 and continue with: 2577 / 523

Step 5:
If we divide 2577 by 523, we get 4 and a remainder of 485.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Subtract 2092 from 2577 to get 485.
Append the next digit (3) from the dividend to 485 and continue with: 4853 / 523

Advancing to step 6:
523 goes into 4853 9 times with a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 1549.0
The remainder is 146 after subtracting 4707 from 4853.
Fetch the next digit (7) from the dividend, attach it to 146 and continue: 1467 / 523

Moving on to step 7:
The number 523 fits into 1467 2 times, leaving a remainder of 421.
Write down 2 as next digit of the result. 
Result so far: 15492.0
Subtract 1046 from 1467 to get 421.
Grab the next digit (1) from the dividend, add it to 421, then carry on: 4211 / 523

Going ahead to step 8:
When dividing 4211 by 523, we get 8 with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 154928.0
Subtracting 4184 from 4211 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
The number 523 fits into 270 0 times, leaving a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 154928.0
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 10:
The number 523 fits into 2700 5 times, leaving a remainder of 85.
The next digit of our result is 5. 
Result so far: 154928.05
Subtracting 2615 from 2700 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 11:
523 goes into 850 1 times with a remainder of 327.
Record the quotient 1 as the next digit in the result. 
Result so far: 154928.051
Subtracting 523 from 850 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 12:
If we divide 3270 by 523, we get 6 and a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 154928.0516
The remainder is 132 after subtracting 3138 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 13:
If we divide 1320 by 523, we get 2 and a remainder of 274.
Use 2 as the next digit of our solution. 
Result so far: 154928.05162
Subtract 1046 from 1320 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 14:
523 can be fit into 2740 5 times, resulting in a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 154928.051625
Subtracting 2615 from 2740 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 15:
523 can be fit into 1250 2 times, resulting in a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 154928.0516252
The remainder is 204 after subtracting 1046 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 16:
When dividing 2040 by 523, we get 3 with a remainder of 471.
The number 3 becomes the next digit in our result. 
Result so far: 154928.05162523
Subtract 1569 from 2040 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Our division results in 154928.05162523 with a remaining 4.71e-07.
