258794 ÷ 84 
The aim is to understand the frequency of 84 in 258794.

Moving on to step 1:
84 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 84

Advancing to step 2:
84 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 84

Advancing to step 3:
When dividing 258 by 84, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 252 from 258, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 84

On to step 4:
When dividing 67 by 84, we get 0 with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtracting 0 from 67 leaves us with 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 84

Advancing to step 5:
84 goes into 679 8 times with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 308.0
Subtract 672 from 679 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 84

Moving on to step 6:
When dividing 74 by 84, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 3080.0
Subtract 0 from 74 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
84 can be fit into 740 8 times, resulting in a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 3080.8
If we take 672 away from 740, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
The number 84 fits into 680 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3080.88
If we subtract 672 from 680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 3080.88, with a leftover of 0.008.
