We look at the division of 80072610 by 84 
The aim is to understand the frequency of 84 in 80072610.

Let's proceed to step 1:
84 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 84

Going ahead to step 2:
If we divide 80 by 84, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 84

On to step 3:
800 divided by 84 is 9 with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 756 from 800 and we're left with 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 84

Moving on to step 4:
When dividing 447 by 84, we get 5 with a remainder of 27.
The next digit of our result is 5. 
Result so far: 95.0
If we take 420 away from 447, we end up with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 84

Moving on to step 5:
84 goes into 272 3 times with a remainder of 20.
The next digit of our result is 3. 
Result so far: 953.0
If we subtract 252 from 272, we get 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 84

Step 6:
206 divided by 84 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 9532.0
If we subtract 168 from 206, we get 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 84

On to step 7:
The number 84 fits into 381 4 times, leaving a remainder of 45.
The number 4 becomes the next digit in our result. 
Result so far: 95324.0
Subtracting 336 from 381 leaves us with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 84

Let's proceed to step 8:
84 can be fit into 450 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 953245.0
If we take 420 away from 450, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
300 divided by 84 is 3 with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 953245.3
Subtracting 252 from 300 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
84 goes into 480 5 times with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 953245.35
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 953245.357
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 953245.3571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 953245.35714
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
84 goes into 240 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 953245.357142
Deduct 168 from 240 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 15:
When dividing 720 by 84, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 953245.3571428
If we subtract 672 from 720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
The number 84 fits into 480 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 953245.35714285
If we subtract 420 from 480, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 953245.35714285 with a remaining 6e-08.
