6902071 divided by 843 
The aim is to understand the frequency of 843 in 6902071.

Advancing to step 1:
When dividing 6 by 843, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 843

Step 2:
If we divide 69 by 843, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Include the next digit (0) from the dividend after 69, then repeat: 690 / 843

Advancing to step 3:
843 goes into 690 0 times with a remainder of 690.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 690, we end up with 690.
Bring next digit (2) of the dividend behind the 690 and repeat the process: 6902 / 843

On to step 4:
843 can be fit into 6902 8 times, resulting in a remainder of 158.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6744 from 6902, we get 158.
Take the next digit (0) from the dividend and append it to 158, then repeat: 1580 / 843

Step 5:
When dividing 1580 by 843, we get 1 with a remainder of 737.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtracting 843 from 1580 leaves us with 737.
Fetch the next digit (7) from the dividend, attach it to 737 and continue: 7377 / 843

On to step 6:
When dividing 7377 by 843, we get 8 with a remainder of 633.
Use 8 as the next digit of our solution. 
Result so far: 818.0
Subtracting 6744 from 7377 leaves us with 633.
Take the next digit (1) from the dividend and append it to 633, then repeat: 6331 / 843

Moving on to step 7:
6331 divided by 843 is 7 with a remainder of 430.
The number 7 becomes the next digit in our result. 
Result so far: 8187.0
If we take 5901 away from 6331, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 8:
If we divide 4300 by 843, we get 5 and a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 8187.5
Subtracting 4215 from 4300 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 9:
The number 843 fits into 850 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 8187.51
Subtract 843 from 850 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
843 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 8187.51
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
When dividing 700 by 843, we get 0 with a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 8187.51
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 8187.51, with a leftover of 0.007.
