440557 divided by 84 
The aim is to understand the frequency of 84 in 440557.

On to step 1:
When dividing 4 by 84, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 84

On to step 2:
84 can be fit into 44 0 times, resulting in a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 84

Moving on to step 3:
440 divided by 84 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 20 after subtracting 420 from 440.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 84

Going ahead to step 4:
When dividing 205 by 84, we get 2 with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 168 from 205 leaves us with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 84

Let's proceed to step 5:
84 can be fit into 375 4 times, resulting in a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 524.0
Deduct 336 from 375 and we're left with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 84

Let's proceed to step 6:
397 divided by 84 is 4 with a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 5244.0
Deduct 336 from 397 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
The number 84 fits into 610 7 times, leaving a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 5244.7
If we take 588 away from 610, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
When dividing 220 by 84, we get 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 5244.72
Deduct 168 from 220 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.

Going ahead to step 9:
520 divided by 84 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 5244.726
If we subtract 504 from 520, we get 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:
If we divide 160 by 84, we get 1 and a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 5244.7261
Subtracting 84 from 160 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
84 goes into 760 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 5244.72619
Subtracting 756 from 760 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
84 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5244.72619
Deduct 0 from 40 and we're left 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.

Step 13:
84 goes into 400 4 times with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 5244.7261904
Deduct 336 from 400 and we're left 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.

On to step 14:
When dividing 640 by 84, we get 7 with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 5244.72619047
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 5244.72619047 with a remainder of 5.2e-08.
