We're dividing 77394552 by 843 
The aim is to understand the frequency of 843 in 77394552.

Moving on to step 1:
The number 843 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 843

Going ahead to step 2:
When dividing 77 by 843, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 843

Let's proceed to step 3:
773 divided by 843 is 0 with a remainder of 773.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 773 to get 773.
Append the next digit (9) from the dividend to 773 and continue with: 7739 / 843

Let's proceed to step 4:
If we divide 7739 by 843, we get 9 and a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 7587 away from 7739, we end up with 152.
Grab the next digit (4) from the dividend, add it to 152, then carry on: 1524 / 843

On to step 5:
843 goes into 1524 1 times with a remainder of 681.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtract 843 from 1524 to get 681.
Append the next digit (5) from the dividend to 681 and continue with: 6815 / 843

Let's proceed to step 6:
843 goes into 6815 8 times with a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 918.0
The remainder is 71 after subtracting 6744 from 6815.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 843

On to step 7:
843 goes into 715 0 times with a remainder of 715.
Write down 0 as next digit of the result. 
Result so far: 9180.0
If we take 0 away from 715, we end up with 715.
Include the next digit (2) from the dividend after 715, then repeat: 7152 / 843

On to step 8:
7152 divided by 843 is 8 with a remainder of 408.
Record the quotient 8 as the next digit in the result. 
Result so far: 91808.0
If we take 6744 away from 7152, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 9:
843 goes into 4080 4 times with a remainder of 708.
Write down 4 as next digit of the result. 
Result so far: 91808.4
If we take 3372 away from 4080, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Advancing to step 10:
7080 divided by 843 is 8 with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 91808.48
If we take 6744 away from 7080, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 11:
If we divide 3360 by 843, we get 3 and a remainder of 831.
Put 3 as the next digit of the answer. 
Result so far: 91808.483
If we subtract 2529 from 3360, we get 831.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8310, and continue the process.

Going ahead to step 12:
8310 divided by 843 is 9 with a remainder of 723.
Record the quotient 9 as the next digit in the result. 
Result so far: 91808.4839
The remainder is 723 after subtracting 7587 from 8310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Moving on to step 13:
When dividing 7230 by 843, we get 8 with a remainder of 486.
The number 8 becomes the next digit in our result. 
Result so far: 91808.48398
The remainder is 486 after subtracting 6744 from 7230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 14:
4860 divided by 843 is 5 with a remainder of 645.
Record the quotient 5 as the next digit in the result. 
Result so far: 91808.483985
Subtract 4215 from 4860 to get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Going ahead to step 15:
The number 843 fits into 6450 7 times, leaving a remainder of 549.
Put 7 as the next digit of the answer. 
Result so far: 91808.4839857
Subtracting 5901 from 6450 leaves us with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Advancing to step 16:
5490 divided by 843 is 6 with a remainder of 432.
Write down 6 as next digit of the result. 
Result so far: 91808.48398576
The remainder is 432 after subtracting 5058 from 5490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

The final outcome is 91808.48398576, with a leftover of 4.32e-07.
