We divide 353623 by 84
The aim is to understand the frequency of 84 in 353623.

Advancing to step 1:
If we divide 3 by 84, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 84

Going ahead to step 2:
The number 84 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 84

Advancing to step 3:
If we divide 353 by 84, we get 4 and a remainder of 17.
The next digit of our result is 4. 
Result so far: 4.0
If we take 336 away from 353, we end up with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 84

Let's proceed to step 4:
176 divided by 84 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtract 168 from 176 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 84

Going ahead to step 5:
84 can be fit into 82 0 times, resulting in a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (3) from the dividend after 82, then repeat: 823 / 84

Step 6:
If we divide 823 by 84, we get 9 and a remainder of 67.
The next digit of our result is 9. 
Result so far: 4209.0
If we subtract 756 from 823, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
84 can be fit into 670 7 times, resulting in a remainder of 82.
The next digit of our result is 7. 
Result so far: 4209.7
Deduct 588 from 670 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 8:
84 goes into 820 9 times with a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 4209.79
If we take 756 away from 820, we end up 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.

Let's proceed to step 9:
If we divide 640 by 84, we get 7 and a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 4209.797
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.

On to step 10:
84 goes into 520 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 4209.7976
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
84 goes into 160 1 times with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 4209.79761
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
760 divided by 84 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 4209.797619
Deduct 756 from 760 and we're left 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.

Going ahead to step 13:
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: 4209.797619
If we take 0 away from 40, we end up 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.

On to step 14:
400 divided by 84 is 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 4209.79761904
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.

The quotient of the division is 4209.79761904, and the remainder is 6.4e-08.
