We're dividing 9561834 by 843 
The aim is to understand the frequency of 843 in 9561834.

Advancing to step 1:
9 divided by 843 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 843

Step 2:
843 can be fit into 95 0 times, resulting in a remainder of 95.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 95, we end up with 95.
Fetch the next digit (6) from the dividend, attach it to 95 and continue: 956 / 843

Step 3:
843 goes into 956 1 times with a remainder of 113.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 843 from 956 leaves us with 113.
Append the next digit (1) from the dividend to 113 and continue with: 1131 / 843

Let's proceed to step 4:
843 can be fit into 1131 1 times, resulting in a remainder of 288.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 843 from 1131 leaves us with 288.
Append the next digit (8) from the dividend to 288 and continue with: 2888 / 843

Advancing to step 5:
2888 divided by 843 is 3 with a remainder of 359.
Use 3 as the next digit of our solution. 
Result so far: 113.0
If we take 2529 away from 2888, we end up with 359.
Take the next digit (3) from the dividend and append it to 359, then repeat: 3593 / 843

Advancing to step 6:
The number 843 fits into 3593 4 times, leaving a remainder of 221.
Use 4 as the next digit of our solution. 
Result so far: 1134.0
Subtract 3372 from 3593 to get 221.
Include the next digit (4) from the dividend after 221, then repeat: 2214 / 843

Going ahead to step 7:
843 can be fit into 2214 2 times, resulting in a remainder of 528.
Write down 2 as next digit of the result. 
Result so far: 11342.0
If we take 1686 away from 2214, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 8:
5280 divided by 843 is 6 with a remainder of 222.
Record the quotient 6 as the next digit in the result. 
Result so far: 11342.6
If we take 5058 away from 5280, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 9:
843 can be fit into 2220 2 times, resulting in a remainder of 534.
Write down 2 as next digit of the result. 
Result so far: 11342.62
Subtracting 1686 from 2220 leaves us with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 10:
5340 divided by 843 is 6 with a remainder of 282.
Put 6 as the next digit of the answer. 
Result so far: 11342.626
Subtracting 5058 from 5340 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 11:
843 can be fit into 2820 3 times, resulting in a remainder of 291.
The number 3 becomes the next digit in our result. 
Result so far: 11342.6263
If we subtract 2529 from 2820, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 12:
If we divide 2910 by 843, we get 3 and a remainder of 381.
The number 3 becomes the next digit in our result. 
Result so far: 11342.62633
Subtracting 2529 from 2910 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

The final outcome is 11342.62633, with a leftover of 0.000381.
