We're dividing 315898 by 84 
The aim is to understand the frequency of 84 in 315898.

On to step 1:
The number 84 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 84

On to step 2:
The number 84 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 84

Advancing to step 3:
If we divide 315 by 84, we get 3 and a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 252 from 315 to get 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 84

Going ahead to step 4:
638 divided by 84 is 7 with a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 588 from 638 to get 50.
Bring next digit (9) of the dividend behind the 50 and repeat the process: 509 / 84

Moving on to step 5:
When dividing 509 by 84, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 376.0
Subtracting 504 from 509 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 84

Advancing to step 6:
84 can be fit into 58 0 times, resulting in a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 3760.0
Subtracting 0 from 58 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
84 goes into 580 6 times with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 3760.6
If we take 504 away from 580, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
760 divided by 84 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 3760.69
If we subtract 756 from 760, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 84 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3760.69
Subtracting 0 from 40 leaves us 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.

Step 10:
84 can be fit into 400 4 times, resulting in a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 3760.6904
The remainder is 64 after subtracting 336 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
640 divided by 84 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 3760.69047
Subtract 588 from 640 to 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.

Moving on to step 12:
84 can be fit into 520 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 3760.690476
Subtracting 504 from 520 leaves us 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 13:
The number 84 fits into 160 1 times, leaving a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 3760.6904761
Subtract 84 from 160 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
84 can be fit into 760 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 3760.69047619
Subtracting 756 from 760 leaves us 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.

The quotient of the division is 3760.69047619, and the remainder is 4e-09.
