Let's divide 66775745 by 843
The aim is to understand the frequency of 843 in 66775745.

Step 1:
843 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 843

Going ahead to step 2:
843 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 843

Moving on to step 3:
The number 843 fits into 667 0 times, leaving a remainder of 667.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 667 leaves us with 667.
Grab the next digit (7) from the dividend, add it to 667, then carry on: 6677 / 843

Let's proceed to step 4:
843 can be fit into 6677 7 times, resulting in a remainder of 776.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 5901 from 6677, we get 776.
Include the next digit (5) from the dividend after 776, then repeat: 7765 / 843

Going ahead to step 5:
When dividing 7765 by 843, we get 9 with a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtract 7587 from 7765 to get 178.
Grab the next digit (7) from the dividend, add it to 178, then carry on: 1787 / 843

Going ahead to step 6:
The number 843 fits into 1787 2 times, leaving a remainder of 101.
Use 2 as the next digit of our solution. 
Result so far: 792.0
Deduct 1686 from 1787 and we're left with 101.
Append the next digit (4) from the dividend to 101 and continue with: 1014 / 843

Advancing to step 7:
When dividing 1014 by 843, we get 1 with a remainder of 171.
Write down 1 as next digit of the result. 
Result so far: 7921.0
If we take 843 away from 1014, we end up with 171.
Fetch the next digit (5) from the dividend, attach it to 171 and continue: 1715 / 843

Step 8:
When dividing 1715 by 843, we get 2 with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 79212.0
Deduct 1686 from 1715 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
When dividing 290 by 843, we get 0 with a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 79212.0
Subtracting 0 from 290 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 10:
When dividing 2900 by 843, we get 3 with a remainder of 371.
The next digit of our result is 3. 
Result so far: 79212.03
If we subtract 2529 from 2900, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 11:
If we divide 3710 by 843, we get 4 and a remainder of 338.
The next digit of our result is 4. 
Result so far: 79212.034
Deduct 3372 from 3710 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 12:
The number 843 fits into 3380 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 79212.0344
The remainder is 8 after subtracting 3372 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 79212.0344 and a remainder of 8e-05.
