381573 ÷ 84 
The aim is to understand the frequency of 84 in 381573.

Going ahead to step 1:
When dividing 3 by 84, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 84

On to step 2:
38 divided by 84 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 84

Let's proceed to step 3:
When dividing 381 by 84, we get 4 with a remainder of 45.
The next digit of our result is 4. 
Result so far: 4.0
If we take 336 away from 381, we end up with 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 84

On to step 4:
If we divide 455 by 84, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 420 from 455 and we're left with 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 84

Step 5:
If we divide 357 by 84, we get 4 and a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 454.0
Subtract 336 from 357 to get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 84

On to step 6:
84 goes into 213 2 times with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 4542.0
The remainder is 45 after subtracting 168 from 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
84 goes into 450 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 4542.5
Subtract 420 from 450 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
84 can be fit into 300 3 times, resulting in a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 4542.53
The remainder is 48 after subtracting 252 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
When dividing 480 by 84, we get 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 4542.535
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.

Moving on to step 10:
84 goes into 600 7 times with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 4542.5357
If we subtract 588 from 600, we get 12.
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:
84 goes into 120 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 4542.53571
Subtracting 84 from 120 leaves us 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.

Step 12:
84 goes into 360 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4542.535714
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 4542.5357142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
When dividing 720 by 84, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 4542.53571428
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.

Our division results in 4542.53571428 with a remaining 4.8e-08.
