We're dividing 740220 by 84 
The aim is to understand the frequency of 84 in 740220.

Moving on to step 1:
7 divided by 84 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 84

Step 2:
74 divided by 84 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 84

Going ahead to step 3:
84 goes into 740 8 times with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 672 from 740 to get 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 84

Moving on to step 4:
84 goes into 682 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtracting 672 from 682 leaves us with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 84

Let's proceed to step 5:
102 divided by 84 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 881.0
Subtracting 84 from 102 leaves us with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 84

Step 6:
When dividing 180 by 84, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 8812.0
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
When dividing 120 by 84, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 8812.1
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
If we divide 360 by 84, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 8812.14
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 8812.142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
84 can be fit into 720 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 8812.1428
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
If we divide 480 by 84, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 8812.14285
If we take 420 away from 480, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
When dividing 600 by 84, we get 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 8812.142857
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
If we divide 120 by 84, we get 1 and a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 8812.1428571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 8812.14285714
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 8812.14285714 with a remainder of 2.4e-08.
