We divide 400223 by 84
The aim is to understand the frequency of 84 in 400223.

Let's proceed to step 1:
84 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 84

Going ahead to step 2:
40 divided by 84 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 84

Advancing to step 3:
84 goes into 400 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 336 from 400 leaves us with 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 84

Moving on to step 4:
The number 84 fits into 642 7 times, leaving a remainder of 54.
The next digit of our result is 7. 
Result so far: 47.0
Subtracting 588 from 642 leaves us with 54.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 84

Advancing to step 5:
The number 84 fits into 542 6 times, leaving a remainder of 38.
The next digit of our result is 6. 
Result so far: 476.0
The remainder is 38 after subtracting 504 from 542.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 84

Step 6:
84 goes into 383 4 times with a remainder of 47.
The next digit of our result is 4. 
Result so far: 4764.0
If we subtract 336 from 383, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
470 divided by 84 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 4764.5
Subtracting 420 from 470 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
If we divide 500 by 84, we get 5 and a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 4764.55
Deduct 420 from 500 and we're left 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.

The final outcome is 4764.55, with a leftover of 0.08.
