We look at the division of 37086 by 84 
The aim is to understand the frequency of 84 in 37086.

Let's proceed to step 1:
When dividing 3 by 84, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 84

Going ahead to step 2:
37 divided by 84 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 84

Advancing to step 3:
When dividing 370 by 84, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 336 from 370 and we're left with 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 84

Going ahead to step 4:
84 can be fit into 348 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtracting 336 from 348 leaves us with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 84

Moving on to step 5:
84 goes into 126 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 441.0
Subtract 84 from 126 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 6:
420 divided by 84 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 441.5
If we subtract 420 from 420, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
84 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 441.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 84 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 441.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 441.5 and a remainder of 0.0.
