20855431 divided by 150 
The aim is to understand the frequency of 150 in 20855431.

On to step 1:
The number 150 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 150

Let's proceed to step 2:
150 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 150

Step 3:
208 divided by 150 is 1 with a remainder of 58.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 150 from 208 to get 58.
Grab the next digit (5) from the dividend, add it to 58, then carry on: 585 / 150

Moving on to step 4:
585 divided by 150 is 3 with a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 450 away from 585, we end up with 135.
Fetch the next digit (5) from the dividend, attach it to 135 and continue: 1355 / 150

Advancing to step 5:
150 can be fit into 1355 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Deduct 1350 from 1355 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 150

On to step 6:
If we divide 54 by 150, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 1390.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 150

On to step 7:
150 goes into 543 3 times with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 13903.0
The remainder is 93 after subtracting 450 from 543.
Append the next digit (1) from the dividend to 93 and continue with: 931 / 150

Going ahead to step 8:
150 goes into 931 6 times with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 139036.0
Subtracting 900 from 931 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
310 divided by 150 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 139036.2
The remainder is 10 after subtracting 300 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
100 divided by 150 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 139036.2
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
If we divide 1000 by 150, we get 6 and a remainder of 100.
The next digit of our result is 6. 
Result so far: 139036.206
Subtracting 900 from 1000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
150 goes into 1000 6 times with a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 139036.2066
If we take 900 away from 1000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 139036.2066 with a remaining 0.001.
