We divide 6231399 by 843
The aim is to understand the frequency of 843 in 6231399.

Advancing to step 1:
When dividing 6 by 843, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 843

Let's proceed to step 2:
When dividing 62 by 843, we get 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 843

Step 3:
When dividing 623 by 843, we get 0 with a remainder of 623.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 623, we get 623.
Include the next digit (1) from the dividend after 623, then repeat: 6231 / 843

Going ahead to step 4:
If we divide 6231 by 843, we get 7 and a remainder of 330.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 5901 from 6231 to get 330.
Include the next digit (3) from the dividend after 330, then repeat: 3303 / 843

Going ahead to step 5:
When dividing 3303 by 843, we get 3 with a remainder of 774.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we take 2529 away from 3303, we end up with 774.
Append the next digit (9) from the dividend to 774 and continue with: 7749 / 843

Moving on to step 6:
When dividing 7749 by 843, we get 9 with a remainder of 162.
Write down 9 as next digit of the result. 
Result so far: 739.0
The remainder is 162 after subtracting 7587 from 7749.
Grab the next digit (9) from the dividend, add it to 162, then carry on: 1629 / 843

Advancing to step 7:
843 goes into 1629 1 times with a remainder of 786.
The next digit of our result is 1. 
Result so far: 7391.0
If we subtract 843 from 1629, we get 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Let's proceed to step 8:
843 goes into 7860 9 times with a remainder of 273.
Put 9 as the next digit of the answer. 
Result so far: 7391.9
Subtracting 7587 from 7860 leaves us 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.

Let's proceed to step 9:
2730 divided by 843 is 3 with a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 7391.93
If we subtract 2529 from 2730, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 10:
843 goes into 2010 2 times with a remainder of 324.
Write down 2 as next digit of the result. 
Result so far: 7391.932
If we take 1686 away from 2010, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 11:
If we divide 3240 by 843, we get 3 and a remainder of 711.
Record the quotient 3 as the next digit in the result. 
Result so far: 7391.9323
The remainder is 711 after subtracting 2529 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Going ahead to step 12:
843 can be fit into 7110 8 times, resulting in a remainder of 366.
Put 8 as the next digit of the answer. 
Result so far: 7391.93238
Deduct 6744 from 7110 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 13:
If we divide 3660 by 843, we get 4 and a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 7391.932384
If we subtract 3372 from 3660, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 14:
2880 divided by 843 is 3 with a remainder of 351.
Write down 3 as next digit of the result. 
Result so far: 7391.9323843
Subtracting 2529 from 2880 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 15:
843 goes into 3510 4 times with a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 7391.93238434
If we take 3372 away from 3510, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final outcome is 7391.93238434, with a leftover of 1.38e-07.
