Let's divide 625409 by 84
The aim is to understand the frequency of 84 in 625409.

Advancing to step 1:
6 divided by 84 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 84

Moving on to step 2:
84 can be fit into 62 0 times, resulting in a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 84

On to step 3:
When dividing 625 by 84, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 37 after subtracting 588 from 625.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 84

Let's proceed to step 4:
374 divided by 84 is 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtract 336 from 374 to get 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 84

Step 5:
If we divide 380 by 84, we get 4 and a remainder of 44.
The next digit of our result is 4. 
Result so far: 744.0
Subtracting 336 from 380 leaves us with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 84

Let's proceed to step 6:
If we divide 449 by 84, we get 5 and a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 7445.0
Subtract 420 from 449 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
290 divided by 84 is 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 7445.3
Deduct 252 from 290 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
380 divided by 84 is 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 7445.34
If we take 336 away from 380, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
The number 84 fits into 440 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 7445.345
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
200 divided by 84 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 7445.3452
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
If we divide 320 by 84, we get 3 and a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 7445.34523
Subtract 252 from 320 to get 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 12:
84 goes into 680 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 7445.345238
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.

Advancing to step 13:
The number 84 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 7445.345238
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
84 goes into 800 9 times with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 7445.34523809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 7445.34523809 with a remaining 4.4e-08.
