99446403 divided by 776 
The aim is to understand the frequency of 776 in 99446403.

Step 1:
776 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 776

On to step 2:
776 can be fit into 99 0 times, resulting in a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Include the next digit (4) from the dividend after 99, then repeat: 994 / 776

On to step 3:
776 goes into 994 1 times with a remainder of 218.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 776 from 994 leaves us with 218.
Append the next digit (4) from the dividend to 218 and continue with: 2184 / 776

Going ahead to step 4:
If we divide 2184 by 776, we get 2 and a remainder of 632.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1552 from 2184 and we're left with 632.
Include the next digit (6) from the dividend after 632, then repeat: 6326 / 776

Advancing to step 5:
When dividing 6326 by 776, we get 8 with a remainder of 118.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Deduct 6208 from 6326 and we're left with 118.
Fetch the next digit (4) from the dividend, attach it to 118 and continue: 1184 / 776

Moving on to step 6:
1184 divided by 776 is 1 with a remainder of 408.
Record the quotient 1 as the next digit in the result. 
Result so far: 1281.0
Subtract 776 from 1184 to get 408.
Append the next digit (0) from the dividend to 408 and continue with: 4080 / 776

Let's proceed to step 7:
If we divide 4080 by 776, we get 5 and a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 12815.0
If we subtract 3880 from 4080, we get 200.
Grab the next digit (3) from the dividend, add it to 200, then carry on: 2003 / 776

Moving on to step 8:
776 goes into 2003 2 times with a remainder of 451.
The number 2 becomes the next digit in our result. 
Result so far: 128152.0
Deduct 1552 from 2003 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 9:
4510 divided by 776 is 5 with a remainder of 630.
The number 5 becomes the next digit in our result. 
Result so far: 128152.5
If we subtract 3880 from 4510, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 10:
If we divide 6300 by 776, we get 8 and a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 128152.58
If we subtract 6208 from 6300, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
776 goes into 920 1 times with a remainder of 144.
The number 1 becomes the next digit in our result. 
Result so far: 128152.581
Deduct 776 from 920 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 12:
When dividing 1440 by 776, we get 1 with a remainder of 664.
The number 1 becomes the next digit in our result. 
Result so far: 128152.5811
If we take 776 away from 1440, we end up with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

The final result is 128152.5811 with a remainder of 0.00664.
