We look at the division of 84698409 by 844 
The aim is to understand the frequency of 844 in 84698409.

Step 1:
When dividing 8 by 844, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 844

Advancing to step 2:
If we divide 84 by 844, we get 0 and a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Take the next digit (6) from the dividend and append it to 84, then repeat: 846 / 844

Moving on to step 3:
If we divide 846 by 844, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 844 from 846 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 844

Moving on to step 4:
844 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 29 to get 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 844

Advancing to step 5:
When dividing 298 by 844, we get 0 with a remainder of 298.
The next digit of our result is 0. 
Result so far: 100.0
Subtract 0 from 298 to get 298.
Take the next digit (4) from the dividend and append it to 298, then repeat: 2984 / 844

Going ahead to step 6:
If we divide 2984 by 844, we get 3 and a remainder of 452.
Use 3 as the next digit of our solution. 
Result so far: 1003.0
Subtracting 2532 from 2984 leaves us with 452.
Grab the next digit (0) from the dividend, add it to 452, then carry on: 4520 / 844

Step 7:
The number 844 fits into 4520 5 times, leaving a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 10035.0
Deduct 4220 from 4520 and we're left with 300.
Include the next digit (9) from the dividend after 300, then repeat: 3009 / 844

Going ahead to step 8:
If we divide 3009 by 844, we get 3 and a remainder of 477.
Put 3 as the next digit of the answer. 
Result so far: 100353.0
If we take 2532 away from 3009, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Advancing to step 9:
4770 divided by 844 is 5 with a remainder of 550.
Write down 5 as next digit of the result. 
Result so far: 100353.5
Subtracting 4220 from 4770 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 10:
844 goes into 5500 6 times with a remainder of 436.
The next digit of our result is 6. 
Result so far: 100353.56
Subtracting 5064 from 5500 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 11:
The number 844 fits into 4360 5 times, leaving a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 100353.565
If we subtract 4220 from 4360, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
1400 divided by 844 is 1 with a remainder of 556.
The number 1 becomes the next digit in our result. 
Result so far: 100353.5651
If we take 844 away from 1400, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 13:
5560 divided by 844 is 6 with a remainder of 496.
Use 6 as the next digit of our solution. 
Result so far: 100353.56516
Subtract 5064 from 5560 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 14:
The number 844 fits into 4960 5 times, leaving a remainder of 740.
Use 5 as the next digit of our solution. 
Result so far: 100353.565165
If we take 4220 away from 4960, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 15:
If we divide 7400 by 844, we get 8 and a remainder of 648.
Put 8 as the next digit of the answer. 
Result so far: 100353.5651658
If we subtract 6752 from 7400, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 16:
The number 844 fits into 6480 7 times, leaving a remainder of 572.
Put 7 as the next digit of the answer. 
Result so far: 100353.56516587
Deduct 5908 from 6480 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

The final outcome is 100353.56516587, with a leftover of 5.72e-07.
