We're dividing 136435 by 840 
The aim is to understand the frequency of 840 in 136435.

Moving on to step 1:
840 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 840

On to step 2:
840 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 840

Moving on to step 3:
840 can be fit into 136 0 times, resulting in a remainder of 136.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 136, we get 136.
Bring next digit (4) of the dividend behind the 136 and repeat the process: 1364 / 840

Going ahead to step 4:
840 can be fit into 1364 1 times, resulting in a remainder of 524.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 840 from 1364 to get 524.
Grab the next digit (3) from the dividend, add it to 524, then carry on: 5243 / 840

Let's proceed to step 5:
840 can be fit into 5243 6 times, resulting in a remainder of 203.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 5040 from 5243 leaves us with 203.
Append the next digit (5) from the dividend to 203 and continue with: 2035 / 840

Moving on to step 6:
840 can be fit into 2035 2 times, resulting in a remainder of 355.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
If we subtract 1680 from 2035, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 7:
840 goes into 3550 4 times with a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 162.4
If we take 3360 away from 3550, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 8:
If we divide 1900 by 840, we get 2 and a remainder of 220.
The next digit of our result is 2. 
Result so far: 162.42
Deduct 1680 from 1900 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 9:
If we divide 2200 by 840, we get 2 and a remainder of 520.
The next digit of our result is 2. 
Result so far: 162.422
Subtract 1680 from 2200 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final outcome is 162.422, with a leftover of 0.052.
