636270 divided by 84 
The aim is to understand the frequency of 84 in 636270.

Going ahead to step 1:
When dividing 6 by 84, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 84

Going ahead to step 2:
The number 84 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Bring next digit (6) of the dividend behind the 63 and repeat the process: 636 / 84

Moving on to step 3:
If we divide 636 by 84, we get 7 and a remainder of 48.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 588 from 636, we get 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 84

Advancing to step 4:
84 goes into 482 5 times with a remainder of 62.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we take 420 away from 482, we end up with 62.
Append the next digit (7) from the dividend to 62 and continue with: 627 / 84

Going ahead to step 5:
If we divide 627 by 84, we get 7 and a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 757.0
If we take 588 away from 627, we end up with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 84

Advancing to step 6:
84 goes into 390 4 times with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 7574.0
Subtracting 336 from 390 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
84 goes into 540 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 7574.6
Subtracting 504 from 540 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
If we divide 360 by 84, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 7574.64
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
When dividing 240 by 84, we get 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 7574.642
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
720 divided by 84 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 7574.6428
Deduct 672 from 720 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
If we divide 480 by 84, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 7574.64285
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
84 can be fit into 600 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 7574.642857
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The next digit of our result is 1. 
Result so far: 7574.6428571
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 7574.64285714
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 7574.64285714, and the remainder is 2.4e-08.
