99678715 ÷ 835 
The aim is to understand the frequency of 835 in 99678715.

Let's proceed to step 1:
835 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 835

Moving on to step 2:
If we divide 99 by 835, we get 0 and a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Append the next digit (6) from the dividend to 99 and continue with: 996 / 835

Step 3:
835 can be fit into 996 1 times, resulting in a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 835 from 996 leaves us with 161.
Fetch the next digit (7) from the dividend, attach it to 161 and continue: 1617 / 835

Advancing to step 4:
835 can be fit into 1617 1 times, resulting in a remainder of 782.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 835 away from 1617, we end up with 782.
Include the next digit (8) from the dividend after 782, then repeat: 7828 / 835

Going ahead to step 5:
7828 divided by 835 is 9 with a remainder of 313.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
If we take 7515 away from 7828, we end up with 313.
Bring next digit (7) of the dividend behind the 313 and repeat the process: 3137 / 835

Let's proceed to step 6:
The number 835 fits into 3137 3 times, leaving a remainder of 632.
Use 3 as the next digit of our solution. 
Result so far: 1193.0
If we subtract 2505 from 3137, we get 632.
Append the next digit (1) from the dividend to 632 and continue with: 6321 / 835

On to step 7:
835 can be fit into 6321 7 times, resulting in a remainder of 476.
Write down 7 as next digit of the result. 
Result so far: 11937.0
If we subtract 5845 from 6321, we get 476.
Grab the next digit (5) from the dividend, add it to 476, then carry on: 4765 / 835

Let's proceed to step 8:
4765 divided by 835 is 5 with a remainder of 590.
Write down 5 as next digit of the result. 
Result so far: 119375.0
If we subtract 4175 from 4765, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 9:
5900 divided by 835 is 7 with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 119375.7
If we subtract 5845 from 5900, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
550 divided by 835 is 0 with a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 119375.7
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 11:
When dividing 5500 by 835, we get 6 with a remainder of 490.
Write down 6 as next digit of the result. 
Result so far: 119375.706
Subtract 5010 from 5500 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 12:
4900 divided by 835 is 5 with a remainder of 725.
Put 5 as the next digit of the answer. 
Result so far: 119375.7065
Subtract 4175 from 4900 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Let's proceed to step 13:
835 can be fit into 7250 8 times, resulting in a remainder of 570.
The next digit of our result is 8. 
Result so far: 119375.70658
Subtracting 6680 from 7250 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 14:
The number 835 fits into 5700 6 times, leaving a remainder of 690.
Use 6 as the next digit of our solution. 
Result so far: 119375.706586
Deduct 5010 from 5700 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 15:
The number 835 fits into 6900 8 times, leaving a remainder of 220.
Record the quotient 8 as the next digit in the result. 
Result so far: 119375.7065868
The remainder is 220 after subtracting 6680 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 16:
The number 835 fits into 2200 2 times, leaving a remainder of 530.
The number 2 becomes the next digit in our result. 
Result so far: 119375.70658682
The remainder is 530 after subtracting 1670 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

The final outcome is 119375.70658682, with a leftover of 5.3e-07.
