We're dividing 99881054 by 781 
The aim is to understand the frequency of 781 in 99881054.

On to step 1:
781 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 781

Moving on to step 2:
When dividing 99 by 781, we get 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Include the next digit (8) from the dividend after 99, then repeat: 998 / 781

On to step 3:
If we divide 998 by 781, we get 1 and a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 781 from 998 leaves us with 217.
Include the next digit (8) from the dividend after 217, then repeat: 2178 / 781

Step 4:
781 goes into 2178 2 times with a remainder of 616.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1562 from 2178, we get 616.
Take the next digit (1) from the dividend and append it to 616, then repeat: 6161 / 781

Let's proceed to step 5:
6161 divided by 781 is 7 with a remainder of 694.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Deduct 5467 from 6161 and we're left with 694.
Bring next digit (0) of the dividend behind the 694 and repeat the process: 6940 / 781

Going ahead to step 6:
The number 781 fits into 6940 8 times, leaving a remainder of 692.
Put 8 as the next digit of the answer. 
Result so far: 1278.0
If we take 6248 away from 6940, we end up with 692.
Take the next digit (5) from the dividend and append it to 692, then repeat: 6925 / 781

Step 7:
The number 781 fits into 6925 8 times, leaving a remainder of 677.
The number 8 becomes the next digit in our result. 
Result so far: 12788.0
Subtracting 6248 from 6925 leaves us with 677.
Append the next digit (4) from the dividend to 677 and continue with: 6774 / 781

Advancing to step 8:
The number 781 fits into 6774 8 times, leaving a remainder of 526.
The next digit of our result is 8. 
Result so far: 127888.0
If we take 6248 away from 6774, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 9:
781 can be fit into 5260 6 times, resulting in a remainder of 574.
The next digit of our result is 6. 
Result so far: 127888.6
Subtracting 4686 from 5260 leaves us with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Going ahead to step 10:
If we divide 5740 by 781, we get 7 and a remainder of 273.
Put 7 as the next digit of the answer. 
Result so far: 127888.67
The remainder is 273 after subtracting 5467 from 5740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 11:
The number 781 fits into 2730 3 times, leaving a remainder of 387.
Record the quotient 3 as the next digit in the result. 
Result so far: 127888.673
The remainder is 387 after subtracting 2343 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 12:
781 can be fit into 3870 4 times, resulting in a remainder of 746.
Use 4 as the next digit of our solution. 
Result so far: 127888.6734
Deduct 3124 from 3870 and we're left with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Going ahead to step 13:
The number 781 fits into 7460 9 times, leaving a remainder of 431.
The number 9 becomes the next digit in our result. 
Result so far: 127888.67349
Subtracting 7029 from 7460 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Advancing to step 14:
If we divide 4310 by 781, we get 5 and a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 127888.673495
Deduct 3905 from 4310 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 15:
781 goes into 4050 5 times with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 127888.6734955
Deduct 3905 from 4050 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

In conclusion, the division gives 127888.6734955 with a balance of 1.45e-06.
