We divide 735639 by 84
The aim is to understand the frequency of 84 in 735639.

Going ahead to step 1:
84 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 84

Step 2:
84 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 84

Step 3:
When dividing 735 by 84, we get 8 with a remainder of 63.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 672 from 735 leaves us with 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 84

Moving on to step 4:
If we divide 636 by 84, we get 7 and a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Subtract 588 from 636 to get 48.
Take the next digit (3) from the dividend and append it to 48, then repeat: 483 / 84

Advancing to step 5:
If we divide 483 by 84, we get 5 and a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 875.0
Subtracting 420 from 483 leaves us with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 84

On to step 6:
If we divide 639 by 84, we get 7 and a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 8757.0
Deduct 588 from 639 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
The number 84 fits into 510 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 8757.6
Subtract 504 from 510 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
84 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 8757.6
If we subtract 0 from 60, 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.

Moving on to step 9:
The number 84 fits into 600 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 8757.607
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.

Step 10:
If we divide 120 by 84, we get 1 and a remainder of 36.
The next digit of our result is 1. 
Result so far: 8757.6071
Subtracting 84 from 120 leaves us with 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 11:
360 divided by 84 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 8757.60714
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
When dividing 240 by 84, we get 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 8757.607142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
If we divide 720 by 84, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 8757.6071428
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 14:
480 divided by 84 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 8757.60714285
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.

The final result is 8757.60714285 with a remainder of 6e-08.
