We look at the division of 78312131 by 181 
Let's see how many times 181 fits into 78312131.

Advancing to step 1:
181 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 181

Going ahead to step 2:
When dividing 78 by 181, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 181

On to step 3:
181 goes into 783 4 times with a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 724 from 783 leaves us with 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 181

Going ahead to step 4:
If we divide 591 by 181, we get 3 and a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 543 from 591 leaves us with 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 181

Step 5:
The number 181 fits into 482 2 times, leaving a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 432.0
If we take 362 away from 482, we end up with 120.
Take the next digit (1) from the dividend and append it to 120, then repeat: 1201 / 181

Going ahead to step 6:
181 can be fit into 1201 6 times, resulting in a remainder of 115.
Record the quotient 6 as the next digit in the result. 
Result so far: 4326.0
The remainder is 115 after subtracting 1086 from 1201.
Bring next digit (3) of the dividend behind the 115 and repeat the process: 1153 / 181

On to step 7:
1153 divided by 181 is 6 with a remainder of 67.
The number 6 becomes the next digit in our result. 
Result so far: 43266.0
The remainder is 67 after subtracting 1086 from 1153.
Take the next digit (1) from the dividend and append it to 67, then repeat: 671 / 181

On to step 8:
181 goes into 671 3 times with a remainder of 128.
Record the quotient 3 as the next digit in the result. 
Result so far: 432663.0
If we take 543 away from 671, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 9:
1280 divided by 181 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 432663.7
If we take 1267 away from 1280, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
When dividing 130 by 181, we get 0 with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 432663.7
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
The number 181 fits into 1300 7 times, leaving a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 432663.707
The remainder is 33 after subtracting 1267 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 12:
When dividing 330 by 181, we get 1 with a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 432663.7071
Deduct 181 from 330 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 13:
181 can be fit into 1490 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 432663.70718
Subtracting 1448 from 1490 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
181 goes into 420 2 times with a remainder of 58.
The next digit of our result is 2. 
Result so far: 432663.707182
Deduct 362 from 420 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 15:
580 divided by 181 is 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 432663.7071823
Subtracting 543 from 580 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 16:
370 divided by 181 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 432663.70718232
The remainder is 8 after subtracting 362 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 432663.70718232 with a balance of 8e-09.
