We're dividing 61893949 by 84 
The aim is to understand the frequency of 84 in 61893949.

Going ahead to step 1:
The number 84 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 84

Going ahead to step 2:
84 can be fit into 61 0 times, resulting in a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Include the next digit (8) from the dividend after 61, then repeat: 618 / 84

Advancing to step 3:
84 goes into 618 7 times with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 588 from 618, we get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 84

Let's proceed to step 4:
The number 84 fits into 309 3 times, leaving a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we subtract 252 from 309, we get 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 84

Let's proceed to step 5:
When dividing 573 by 84, we get 6 with a remainder of 69.
Record the quotient 6 as the next digit in the result. 
Result so far: 736.0
Subtract 504 from 573 to get 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 84

Step 6:
699 divided by 84 is 8 with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 7368.0
Subtract 672 from 699 to get 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 84

Let's proceed to step 7:
When dividing 274 by 84, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 73683.0
If we take 252 away from 274, we end up with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 84

Let's proceed to step 8:
When dividing 229 by 84, we get 2 with a remainder of 61.
Use 2 as the next digit of our solution. 
Result so far: 736832.0
If we take 168 away from 229, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
84 goes into 610 7 times with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 736832.7
If we subtract 588 from 610, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
220 divided by 84 is 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 736832.72
If we take 168 away from 220, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
520 divided by 84 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 736832.726
Deduct 504 from 520 and we're left 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.

Advancing to step 12:
If we divide 160 by 84, we get 1 and a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 736832.7261
If we subtract 84 from 160, we 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.

Going ahead to step 13:
760 divided by 84 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 736832.72619
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 14:
If we divide 40 by 84, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 736832.72619
Deduct 0 from 40 and we're left 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.

Moving on to step 15:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 736832.7261904
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 16:
If we divide 640 by 84, we get 7 and a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 736832.72619047
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.

The final outcome is 736832.72619047, with a leftover of 5.2e-08.
