We divide 813977 by 84
The aim is to understand the frequency of 84 in 813977.

Moving on to step 1:
If we divide 8 by 84, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 84

Step 2:
If we divide 81 by 84, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (3) from the dividend, add it to 81, then carry on: 813 / 84

Let's proceed to step 3:
84 can be fit into 813 9 times, resulting in a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 756 away from 813, we end up with 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 84

Advancing to step 4:
84 goes into 579 6 times with a remainder of 75.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtract 504 from 579 to get 75.
Grab the next digit (7) from the dividend, add it to 75, then carry on: 757 / 84

Advancing to step 5:
If we divide 757 by 84, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 969.0
Deduct 756 from 757 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 84

Going ahead to step 6:
If we divide 17 by 84, we get 0 and a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 9690.0
Subtracting 0 from 17 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 84, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 9690.2
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 84 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9690.2
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 9690.202
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
When dividing 320 by 84, we get 3 with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 9690.2023
Subtracting 252 from 320 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
84 goes into 680 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 9690.20238
Deduct 672 from 680 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
When dividing 80 by 84, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 9690.20238
If we take 0 away from 80, we end up 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.

Advancing to step 13:
84 goes into 800 9 times with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 9690.2023809
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
84 goes into 440 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 9690.20238095
If we take 420 away from 440, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 9690.20238095 with a remainder of 2e-08.
