We're dividing 591442 by 84 
The aim is to understand the frequency of 84 in 591442.

Moving on to step 1:
84 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 84

Moving on to step 2:
84 can be fit into 59 0 times, resulting in a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 84

Step 3:
84 goes into 591 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 588 from 591 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 84

Advancing to step 4:
If we divide 34 by 84, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we take 0 away from 34, we end up with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 84

Going ahead to step 5:
84 can be fit into 344 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 704.0
The remainder is 8 after subtracting 336 from 344.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 84

Moving on to step 6:
The number 84 fits into 82 0 times, leaving a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 7040.0
If we take 0 away from 82, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 7:
When dividing 820 by 84, we get 9 with a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 7040.9
The remainder is 64 after subtracting 756 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
When dividing 640 by 84, we get 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 7040.97
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
The number 84 fits into 520 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 7040.976
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
84 can be fit into 160 1 times, resulting in a remainder of 76.
The next digit of our result is 1. 
Result so far: 7040.9761
Subtract 84 from 160 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
When dividing 760 by 84, we get 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 7040.97619
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
If we divide 40 by 84, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 7040.97619
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
84 can be fit into 400 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 7040.9761904
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
84 goes into 640 7 times with a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 7040.97619047
If we subtract 588 from 640, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 7040.97619047 with a remainder of 5.2e-08.
