Let's divide 837946 by 84
The aim is to understand the frequency of 84 in 837946.

Step 1:
84 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 84

On to step 2:
84 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (7) from the dividend after 83, then repeat: 837 / 84

On to step 3:
84 goes into 837 9 times with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 756 from 837 to get 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 84

Moving on to step 4:
84 goes into 819 9 times with a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Deduct 756 from 819 and we're left with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 84

On to step 5:
84 goes into 634 7 times with a remainder of 46.
The next digit of our result is 7. 
Result so far: 997.0
Subtracting 588 from 634 leaves us with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 84

Going ahead to step 6:
466 divided by 84 is 5 with a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 9975.0
Deduct 420 from 466 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
When dividing 460 by 84, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 9975.5
Subtracting 420 from 460 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
When dividing 400 by 84, we get 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 9975.54
Subtract 336 from 400 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
640 divided by 84 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 9975.547
Subtracting 588 from 640 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
84 can be fit into 520 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 9975.5476
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
160 divided by 84 is 1 with a remainder of 76.
The next digit of our result is 1. 
Result so far: 9975.54761
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
The number 84 fits into 760 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 9975.547619
If we subtract 756 from 760, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
When dividing 40 by 84, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9975.547619
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
84 goes into 400 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 9975.54761904
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 9975.54761904 with a remainder of 6.4e-08.
