We divide 637908 by 84
The aim is to understand the frequency of 84 in 637908.

Step 1:
The number 84 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 84

Step 2:
The number 84 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 84

Step 3:
84 goes into 637 7 times with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 588 from 637, we get 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 84

Advancing to step 4:
84 goes into 499 5 times with a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we take 420 away from 499, we end up with 79.
Bring next digit (0) of the dividend behind the 79 and repeat the process: 790 / 84

Advancing to step 5:
84 can be fit into 790 9 times, resulting in a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 759.0
If we take 756 away from 790, we end up with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 84

Step 6:
If we divide 348 by 84, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 7594.0
If we subtract 336 from 348, we get 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 7:
84 goes into 120 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 7594.1
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.

Step 8:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 7594.14
If we subtract 336 from 360, we 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.

Advancing to step 9:
When dividing 240 by 84, we get 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 7594.142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
The number 84 fits into 720 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 7594.1428
If we take 672 away from 720, we end up 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.

Advancing to step 11:
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: 7594.14285
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.

Going ahead to step 12:
When dividing 600 by 84, we get 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 7594.142857
Subtract 588 from 600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 7594.1428571
If we subtract 84 from 120, we 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.

Moving on to step 14:
When dividing 360 by 84, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 7594.14285714
Subtracting 336 from 360 leaves us 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.

The final outcome is 7594.14285714, with a leftover of 2.4e-08.
