81317439 ÷ 157 
We're looking to find how many times 157 goes into 81317439.

Step 1:
8 divided by 157 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 157

Moving on to step 2:
157 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 157

On to step 3:
If we divide 813 by 157, we get 5 and a remainder of 28.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 28 after subtracting 785 from 813.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 157

Advancing to step 4:
281 divided by 157 is 1 with a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 51.0
Deduct 157 from 281 and we're left with 124.
Append the next digit (7) from the dividend to 124 and continue with: 1247 / 157

Going ahead to step 5:
157 can be fit into 1247 7 times, resulting in a remainder of 148.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.0
If we take 1099 away from 1247, we end up with 148.
Fetch the next digit (4) from the dividend, attach it to 148 and continue: 1484 / 157

Step 6:
If we divide 1484 by 157, we get 9 and a remainder of 71.
The next digit of our result is 9. 
Result so far: 5179.0
If we subtract 1413 from 1484, we get 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 157

Let's proceed to step 7:
157 can be fit into 713 4 times, resulting in a remainder of 85.
The next digit of our result is 4. 
Result so far: 51794.0
Subtracting 628 from 713 leaves us with 85.
Append the next digit (9) from the dividend to 85 and continue with: 859 / 157

Going ahead to step 8:
157 can be fit into 859 5 times, resulting in a remainder of 74.
Write down 5 as next digit of the result. 
Result so far: 517945.0
Deduct 785 from 859 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.

Step 9:
If we divide 740 by 157, we get 4 and a remainder of 112.
The next digit of our result is 4. 
Result so far: 517945.4
The remainder is 112 after subtracting 628 from 740.
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 10:
157 can be fit into 1120 7 times, resulting in a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 517945.47
If we subtract 1099 from 1120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
The number 157 fits into 210 1 times, leaving a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 517945.471
The remainder is 53 after subtracting 157 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 12:
157 can be fit into 530 3 times, resulting in a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 517945.4713
Deduct 471 from 530 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 13:
590 divided by 157 is 3 with a remainder of 119.
Write down 3 as next digit of the result. 
Result so far: 517945.47133
The remainder is 119 after subtracting 471 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

In conclusion, the division gives 517945.47133 with a balance of 0.000119.
