76238254 ÷ 84 
The aim is to understand the frequency of 84 in 76238254.

Going ahead to step 1:
84 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 84

Moving on to step 2:
The number 84 fits into 76 0 times, leaving a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Include the next digit (2) from the dividend after 76, then repeat: 762 / 84

On to step 3:
If we divide 762 by 84, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 6 after subtracting 756 from 762.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 84

Step 4:
When dividing 63 by 84, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
The remainder is 63 after subtracting 0 from 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 84

Moving on to step 5:
84 can be fit into 638 7 times, resulting in a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 907.0
If we take 588 away from 638, we end up with 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 84

On to step 6:
The number 84 fits into 502 5 times, leaving a remainder of 82.
The number 5 becomes the next digit in our result. 
Result so far: 9075.0
Subtract 420 from 502 to get 82.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 84

Step 7:
The number 84 fits into 825 9 times, leaving a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 90759.0
If we subtract 756 from 825, we get 69.
Take the next digit (4) from the dividend and append it to 69, then repeat: 694 / 84

Going ahead to step 8:
If we divide 694 by 84, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 907598.0
If we subtract 672 from 694, 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.

Moving on to step 9:
84 goes into 220 2 times with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 907598.2
Subtract 168 from 220 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.

Advancing to step 10:
84 can be fit into 520 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 907598.26
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.

Going ahead to step 11:
The number 84 fits into 160 1 times, leaving a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 907598.261
Deduct 84 from 160 and we're left 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.

Step 12:
The number 84 fits into 760 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 907598.2619
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.
Put 0 as the next digit of the answer. 
Result so far: 907598.2619
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 14:
84 goes into 400 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 907598.261904
If we take 336 away from 400, 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.

Going ahead to step 15:
640 divided by 84 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 907598.2619047
Deduct 588 from 640 and we're left 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.

On to step 16:
When dividing 520 by 84, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 907598.26190476
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.

The final outcome is 907598.26190476, with a leftover of 1.6e-08.
