We look at the division of 351481 by 84 
The aim is to understand the frequency of 84 in 351481.

Let's proceed to step 1:
3 divided by 84 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 84

Advancing to step 2:
84 goes into 35 0 times with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 84

Let's proceed to step 3:
84 can be fit into 351 4 times, resulting in a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 15 after subtracting 336 from 351.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 84

Going ahead to step 4:
If we divide 154 by 84, we get 1 and a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
The remainder is 70 after subtracting 84 from 154.
Fetch the next digit (8) from the dividend, attach it to 70 and continue: 708 / 84

Moving on to step 5:
When dividing 708 by 84, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 418.0
Deduct 672 from 708 and we're left with 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 84

Moving on to step 6:
84 can be fit into 361 4 times, resulting in a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 4184.0
The remainder is 25 after subtracting 336 from 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
250 divided by 84 is 2 with a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 4184.2
Subtracting 168 from 250 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 8:
When dividing 820 by 84, we get 9 with a remainder of 64.
The next digit of our result is 9. 
Result so far: 4184.29
If we take 756 away from 820, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
If we divide 640 by 84, we get 7 and a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 4184.297
If we take 588 away from 640, we end up 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.

Let's proceed to step 10:
When dividing 520 by 84, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 4184.2976
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.

On to step 11:
If we divide 160 by 84, we get 1 and a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 4184.29761
If we take 84 away from 160, we end up 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.

Going ahead to step 12:
If we divide 760 by 84, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 4184.297619
If we take 756 away from 760, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
84 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 4184.297619
If we take 0 away from 40, we end up 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.

On to step 14:
400 divided by 84 is 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 4184.29761904
Deduct 336 from 400 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 4184.29761904 with a remaining 6.4e-08.
