We're dividing 81031787 by 122 
We want to divide 81031787 by 122.

Let's proceed to step 1:
8 divided by 122 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.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 122

On to step 2:
When dividing 81 by 122, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 122

Advancing to step 3:
When dividing 810 by 122, we get 6 with a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 732 from 810 and we're left with 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 122

Moving on to step 4:
When dividing 783 by 122, we get 6 with a remainder of 51.
The next digit of our result is 6. 
Result so far: 66.0
Subtracting 732 from 783 leaves us with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 122

Step 5:
122 can be fit into 511 4 times, resulting in a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 664.0
If we take 488 away from 511, we end up with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 122

On to step 6:
The number 122 fits into 237 1 times, leaving a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 6641.0
Deduct 122 from 237 and we're left with 115.
Fetch the next digit (8) from the dividend, attach it to 115 and continue: 1158 / 122

Let's proceed to step 7:
If we divide 1158 by 122, we get 9 and a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 66419.0
Subtract 1098 from 1158 to get 60.
Bring next digit (7) of the dividend behind the 60 and repeat the process: 607 / 122

Going ahead to step 8:
The number 122 fits into 607 4 times, leaving a remainder of 119.
Use 4 as the next digit of our solution. 
Result so far: 664194.0
Subtract 488 from 607 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 9:
1190 divided by 122 is 9 with a remainder of 92.
The number 9 becomes the next digit in our result. 
Result so far: 664194.9
Deduct 1098 from 1190 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 10:
If we divide 920 by 122, we get 7 and a remainder of 66.
Write down 7 as next digit of the result. 
Result so far: 664194.97
If we take 854 away from 920, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
The number 122 fits into 660 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 664194.975
If we take 610 away from 660, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
When dividing 500 by 122, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 664194.9754
Subtracting 488 from 500 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
When dividing 120 by 122, we get 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 664194.9754
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
The number 122 fits into 1200 9 times, leaving a remainder of 102.
The next digit of our result is 9. 
Result so far: 664194.975409
The remainder is 102 after subtracting 1098 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 15:
When dividing 1020 by 122, we get 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 664194.9754098
Subtract 976 from 1020 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 16:
122 goes into 440 3 times with a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 664194.97540983
Deduct 366 from 440 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.

In conclusion, the division gives 664194.97540983 with a balance of 7.4e-08.
