We're dividing 35390752 by 843 
The aim is to understand the frequency of 843 in 35390752.

Going ahead to step 1:
3 divided by 843 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 843

Going ahead to step 2:
843 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 843

Going ahead to step 3:
353 divided by 843 is 0 with a remainder of 353.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 353, we end up with 353.
Fetch the next digit (9) from the dividend, attach it to 353 and continue: 3539 / 843

Step 4:
843 can be fit into 3539 4 times, resulting in a remainder of 167.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3372 from 3539 and we're left with 167.
Grab the next digit (0) from the dividend, add it to 167, then carry on: 1670 / 843

Let's proceed to step 5:
If we divide 1670 by 843, we get 1 and a remainder of 827.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 827 after subtracting 843 from 1670.
Grab the next digit (7) from the dividend, add it to 827, then carry on: 8277 / 843

Step 6:
If we divide 8277 by 843, we get 9 and a remainder of 690.
Use 9 as the next digit of our solution. 
Result so far: 419.0
Subtract 7587 from 8277 to get 690.
Grab the next digit (5) from the dividend, add it to 690, then carry on: 6905 / 843

Step 7:
6905 divided by 843 is 8 with a remainder of 161.
The next digit of our result is 8. 
Result so far: 4198.0
Deduct 6744 from 6905 and we're left with 161.
Append the next digit (2) from the dividend to 161 and continue with: 1612 / 843

Let's proceed to step 8:
1612 divided by 843 is 1 with a remainder of 769.
Use 1 as the next digit of our solution. 
Result so far: 41981.0
The remainder is 769 after subtracting 843 from 1612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Step 9:
When dividing 7690 by 843, we get 9 with a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 41981.9
Subtracting 7587 from 7690 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 10:
843 can be fit into 1030 1 times, resulting in a remainder of 187.
Put 1 as the next digit of the answer. 
Result so far: 41981.91
Deduct 843 from 1030 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 11:
843 goes into 1870 2 times with a remainder of 184.
The next digit of our result is 2. 
Result so far: 41981.912
If we subtract 1686 from 1870, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 12:
If we divide 1840 by 843, we get 2 and a remainder of 154.
Use 2 as the next digit of our solution. 
Result so far: 41981.9122
The remainder is 154 after subtracting 1686 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final result is 41981.9122 with a remainder of 0.00154.
