623241 divided by 84 
The aim is to understand the frequency of 84 in 623241.

Moving on to step 1:
6 divided by 84 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in 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

Advancing to step 2:
The number 84 fits into 62 0 times, leaving a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 84

Advancing to step 3:
84 can be fit into 623 7 times, resulting in a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 35 after subtracting 588 from 623.
Grab the next digit (2) from the dividend, add it to 35, then carry on: 352 / 84

Advancing to step 4:
84 goes into 352 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Deduct 336 from 352 and we're left with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 84

Moving on to step 5:
84 can be fit into 164 1 times, resulting in a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 741.0
If we subtract 84 from 164, we get 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 84

Advancing to step 6:
801 divided by 84 is 9 with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 7419.0
If we subtract 756 from 801, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
If we divide 450 by 84, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 7419.5
Deduct 420 from 450 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 84 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 7419.53
If we take 252 away from 300, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
The number 84 fits into 480 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 7419.535
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
If we divide 600 by 84, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 7419.5357
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 84 is 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 7419.53571
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.

On to step 12:
If we divide 360 by 84, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 7419.535714
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
If we divide 240 by 84, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 7419.5357142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
720 divided by 84 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 7419.53571428
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 7419.53571428 and a remainder of 4.8e-08.
