98430077 ÷ 838 
The aim is to understand the frequency of 838 in 98430077.

Advancing to step 1:
838 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 838

Let's proceed to step 2:
98 divided by 838 is 0 with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Take the next digit (4) from the dividend and append it to 98, then repeat: 984 / 838

Step 3:
838 can be fit into 984 1 times, resulting in a remainder of 146.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 838 away from 984, we end up with 146.
Append the next digit (3) from the dividend to 146 and continue with: 1463 / 838

Step 4:
1463 divided by 838 is 1 with a remainder of 625.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 838 from 1463 leaves us with 625.
Bring next digit (0) of the dividend behind the 625 and repeat the process: 6250 / 838

Going ahead to step 5:
6250 divided by 838 is 7 with a remainder of 384.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtract 5866 from 6250 to get 384.
Append the next digit (0) from the dividend to 384 and continue with: 3840 / 838

On to step 6:
If we divide 3840 by 838, we get 4 and a remainder of 488.
Put 4 as the next digit of the answer. 
Result so far: 1174.0
Subtracting 3352 from 3840 leaves us with 488.
Append the next digit (7) from the dividend to 488 and continue with: 4887 / 838

On to step 7:
4887 divided by 838 is 5 with a remainder of 697.
The number 5 becomes the next digit in our result. 
Result so far: 11745.0
Subtracting 4190 from 4887 leaves us with 697.
Include the next digit (7) from the dividend after 697, then repeat: 6977 / 838

Step 8:
When dividing 6977 by 838, we get 8 with a remainder of 273.
Write down 8 as next digit of the result. 
Result so far: 117458.0
If we take 6704 away from 6977, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Step 9:
838 can be fit into 2730 3 times, resulting in a remainder of 216.
The next digit of our result is 3. 
Result so far: 117458.3
If we subtract 2514 from 2730, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 10:
838 goes into 2160 2 times with a remainder of 484.
The number 2 becomes the next digit in our result. 
Result so far: 117458.32
If we take 1676 away from 2160, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 11:
4840 divided by 838 is 5 with a remainder of 650.
Write down 5 as next digit of the result. 
Result so far: 117458.325
Subtracting 4190 from 4840 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 12:
838 can be fit into 6500 7 times, resulting in a remainder of 634.
Write down 7 as next digit of the result. 
Result so far: 117458.3257
Subtract 5866 from 6500 to get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Going ahead to step 13:
If we divide 6340 by 838, we get 7 and a remainder of 474.
The number 7 becomes the next digit in our result. 
Result so far: 117458.32577
If we take 5866 away from 6340, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

The final result is 117458.32577 with a remainder of 0.000474.
