Let's divide 141020 by 816
The aim is to understand the frequency of 816 in 141020.

Moving on to step 1:
816 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 816

Going ahead to step 2:
14 divided by 816 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 816

Going ahead to step 3:
The number 816 fits into 141 0 times, leaving a remainder of 141.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 141, we get 141.
Fetch the next digit (0) from the dividend, attach it to 141 and continue: 1410 / 816

On to step 4:
1410 divided by 816 is 1 with a remainder of 594.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 594 after subtracting 816 from 1410.
Fetch the next digit (2) from the dividend, attach it to 594 and continue: 5942 / 816

Let's proceed to step 5:
The number 816 fits into 5942 7 times, leaving a remainder of 230.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 5712 from 5942 to get 230.
Take the next digit (0) from the dividend and append it to 230, then repeat: 2300 / 816

Going ahead to step 6:
816 can be fit into 2300 2 times, resulting in a remainder of 668.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
Subtracting 1632 from 2300 leaves us with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Advancing to step 7:
If we divide 6680 by 816, we get 8 and a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 172.8
The remainder is 152 after subtracting 6528 from 6680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 8:
When dividing 1520 by 816, we get 1 with a remainder of 704.
Record the quotient 1 as the next digit in the result. 
Result so far: 172.81
Deduct 816 from 1520 and we're left with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Step 9:
When dividing 7040 by 816, we get 8 with a remainder of 512.
Use 8 as the next digit of our solution. 
Result so far: 172.818
If we subtract 6528 from 7040, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 10:
The number 816 fits into 5120 6 times, leaving a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 172.8186
If we take 4896 away from 5120, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 11:
If we divide 2240 by 816, we get 2 and a remainder of 608.
Write down 2 as next digit of the result. 
Result so far: 172.81862
Subtract 1632 from 2240 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 12:
The number 816 fits into 6080 7 times, leaving a remainder of 368.
The number 7 becomes the next digit in our result. 
Result so far: 172.818627
If we take 5712 away from 6080, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 13:
If we divide 3680 by 816, we get 4 and a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 172.8186274
Subtracting 3264 from 3680 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 14:
The number 816 fits into 4160 5 times, leaving a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 172.81862745
Deduct 4080 from 4160 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 172.81862745 with a remaining 8e-08.
