Let's divide 843213 by 153
The aim is to understand the frequency of 153 in 843213.

Advancing to step 1:
8 divided by 153 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 153

Moving on to step 2:
When dividing 84 by 153, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 153

On to step 3:
When dividing 843 by 153, we get 5 with a remainder of 78.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 78 after subtracting 765 from 843.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 153

Moving on to step 4:
When dividing 782 by 153, we get 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we take 765 away from 782, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 153

Let's proceed to step 5:
When dividing 171 by 153, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 551.0
If we subtract 153 from 171, we get 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 153

Advancing to step 6:
183 divided by 153 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 5511.0
Subtract 153 from 183 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
If we divide 300 by 153, we get 1 and a remainder of 147.
The next digit of our result is 1. 
Result so far: 5511.1
The remainder is 147 after subtracting 153 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 8:
If we divide 1470 by 153, we get 9 and a remainder of 93.
Put 9 as the next digit of the answer. 
Result so far: 5511.19
The remainder is 93 after subtracting 1377 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 9:
If we divide 930 by 153, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 5511.196
If we subtract 918 from 930, 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.

Advancing to step 10:
The number 153 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 5511.196
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
153 can be fit into 1200 7 times, resulting in a remainder of 129.
Put 7 as the next digit of the answer. 
Result so far: 5511.19607
Subtracting 1071 from 1200 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 12:
1290 divided by 153 is 8 with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 5511.196078
If we subtract 1224 from 1290, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
660 divided by 153 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 5511.1960784
If we subtract 612 from 660, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
The number 153 fits into 480 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 5511.19607843
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 5511.19607843 with a remaining 2.1e-08.
