Let's divide 437751 by 84
The aim is to understand the frequency of 84 in 437751.

Moving on to step 1:
The number 84 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 84

Step 2:
43 divided by 84 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 84

Going ahead to step 3:
The number 84 fits into 437 5 times, leaving a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 17 after subtracting 420 from 437.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 84

Moving on to step 4:
If we divide 177 by 84, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtracting 168 from 177 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 84

Going ahead to step 5:
The number 84 fits into 95 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 521.0
If we take 84 away from 95, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 84

Let's proceed to step 6:
84 can be fit into 111 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 5211.0
Subtract 84 from 111 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
If we divide 270 by 84, we get 3 and a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 5211.3
If we take 252 away from 270, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
84 goes into 180 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 5211.32
Deduct 168 from 180 and we're left 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.

On to step 9:
If we divide 120 by 84, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 5211.321
Subtract 84 from 120 to 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.

On to step 10:
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: 5211.3214
If we take 336 away from 360, we end up with 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 11:
If we divide 240 by 84, we get 2 and a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 5211.32142
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
When dividing 720 by 84, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 5211.321428
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.

Moving on to step 13:
84 goes into 480 5 times with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 5211.3214285
If we take 420 away from 480, we end up 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.

Advancing to step 14:
When dividing 600 by 84, we get 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 5211.32142857
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 5211.32142857 with a remainder of 1.2e-08.
