We divide 71021 by 84
The aim is to understand the frequency of 84 in 71021.

Moving on to step 1:
84 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 84

Moving on to step 2:
71 divided by 84 is 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Fetch the next digit (0) from the dividend, attach it to 71 and continue: 710 / 84

Moving on to step 3:
When dividing 710 by 84, we get 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 672 from 710 leaves us with 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 84

Moving on to step 4:
84 can be fit into 382 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 84.0
If we subtract 336 from 382, we get 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 84

Let's proceed to step 5:
461 divided by 84 is 5 with a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 845.0
Subtract 420 from 461 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 6:
84 can be fit into 410 4 times, resulting in a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 845.4
If we take 336 away from 410, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 7:
When dividing 740 by 84, we get 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 845.48
Deduct 672 from 740 and we're left 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.

Advancing to step 8:
84 goes into 680 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 845.488
If we take 672 away from 680, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 845.488 and a remainder of 0.0008.
