We look at the division of 700685 by 84 
The aim is to understand the frequency of 84 in 700685.

Moving on to step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 84

Moving on to step 2:
84 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 84

Advancing to step 3:
84 goes into 700 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 672 from 700 leaves us with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 84

Advancing to step 4:
286 divided by 84 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we subtract 252 from 286, we get 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 84

Moving on to step 5:
When dividing 348 by 84, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 834.0
Deduct 336 from 348 and we're left with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 84

Moving on to step 6:
84 can be fit into 125 1 times, resulting in a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 8341.0
Deduct 84 from 125 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
84 can be fit into 410 4 times, resulting in a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 8341.4
Subtracting 336 from 410 leaves us 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.

Moving on to step 8:
The number 84 fits into 740 8 times, leaving a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 8341.48
Subtracting 672 from 740 leaves us 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 9:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8341.488
Subtracting 672 from 680 leaves us 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.

The final result is 8341.488 with a remainder of 0.0008.
