We look at the division of 96949977 by 783 
The aim is to understand the frequency of 783 in 96949977.

Advancing to step 1:
When dividing 9 by 783, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 783

On to step 2:
96 divided by 783 is 0 with a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 96 after subtracting 0 from 96.
Bring next digit (9) of the dividend behind the 96 and repeat the process: 969 / 783

Let's proceed to step 3:
If we divide 969 by 783, we get 1 and a remainder of 186.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 783 from 969 and we're left with 186.
Include the next digit (4) from the dividend after 186, then repeat: 1864 / 783

Let's proceed to step 4:
783 goes into 1864 2 times with a remainder of 298.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 298 after subtracting 1566 from 1864.
Append the next digit (9) from the dividend to 298 and continue with: 2989 / 783

Step 5:
If we divide 2989 by 783, we get 3 and a remainder of 640.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Deduct 2349 from 2989 and we're left with 640.
Grab the next digit (9) from the dividend, add it to 640, then carry on: 6409 / 783

Step 6:
If we divide 6409 by 783, we get 8 and a remainder of 145.
The next digit of our result is 8. 
Result so far: 1238.0
Deduct 6264 from 6409 and we're left with 145.
Bring next digit (7) of the dividend behind the 145 and repeat the process: 1457 / 783

Moving on to step 7:
783 can be fit into 1457 1 times, resulting in a remainder of 674.
Put 1 as the next digit of the answer. 
Result so far: 12381.0
The remainder is 674 after subtracting 783 from 1457.
Take the next digit (7) from the dividend and append it to 674, then repeat: 6747 / 783

On to step 8:
783 goes into 6747 8 times with a remainder of 483.
The number 8 becomes the next digit in our result. 
Result so far: 123818.0
The remainder is 483 after subtracting 6264 from 6747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

On to step 9:
When dividing 4830 by 783, we get 6 with a remainder of 132.
The next digit of our result is 6. 
Result so far: 123818.6
Subtracting 4698 from 4830 leaves us with 132.
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 10:
When dividing 1320 by 783, we get 1 with a remainder of 537.
Write down 1 as next digit of the result. 
Result so far: 123818.61
Subtracting 783 from 1320 leaves us with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Step 11:
When dividing 5370 by 783, we get 6 with a remainder of 672.
Record the quotient 6 as the next digit in the result. 
Result so far: 123818.616
Deduct 4698 from 5370 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 12:
6720 divided by 783 is 8 with a remainder of 456.
The next digit of our result is 8. 
Result so far: 123818.6168
If we subtract 6264 from 6720, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 13:
The number 783 fits into 4560 5 times, leaving a remainder of 645.
Write down 5 as next digit of the result. 
Result so far: 123818.61685
The remainder is 645 after subtracting 3915 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Advancing to step 14:
The number 783 fits into 6450 8 times, leaving a remainder of 186.
Record the quotient 8 as the next digit in the result. 
Result so far: 123818.616858
If we subtract 6264 from 6450, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 15:
If we divide 1860 by 783, we get 2 and a remainder of 294.
The next digit of our result is 2. 
Result so far: 123818.6168582
Subtracting 1566 from 1860 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 16:
783 goes into 2940 3 times with a remainder of 591.
Use 3 as the next digit of our solution. 
Result so far: 123818.61685823
Subtracting 2349 from 2940 leaves us with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

The final result is 123818.61685823 with a remainder of 5.91e-07.
