284137 ÷ 84 
The aim is to understand the frequency of 84 in 284137.

On to step 1:
When dividing 2 by 84, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 84

Advancing to step 2:
28 divided by 84 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 84

Going ahead to step 3:
284 divided by 84 is 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 252 from 284 and we're left with 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 84

Advancing to step 4:
84 goes into 321 3 times with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Deduct 252 from 321 and we're left with 69.
Fetch the next digit (3) from the dividend, attach it to 69 and continue: 693 / 84

Advancing to step 5:
693 divided by 84 is 8 with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 338.0
Deduct 672 from 693 and we're left with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 84

Let's proceed to step 6:
84 can be fit into 217 2 times, resulting in a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 3382.0
If we subtract 168 from 217, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
84 goes into 490 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 3382.5
Deduct 420 from 490 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
If we divide 700 by 84, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 3382.58
The remainder is 28 after subtracting 672 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
When dividing 280 by 84, we get 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 3382.583
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
280 divided by 84 is 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 3382.5833
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 3382.5833, and the remainder is 0.00028.
