We look at the division of 541321 by 83 
The aim is to understand the frequency of 83 in 541321.

Let's proceed to step 1:
When dividing 5 by 83, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 83

Moving on to step 2:
83 can be fit into 54 0 times, resulting in a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 83

On to step 3:
83 can be fit into 541 6 times, resulting in a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 498 from 541, we get 43.
Append the next digit (3) from the dividend to 43 and continue with: 433 / 83

Moving on to step 4:
83 goes into 433 5 times with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 65.0
If we subtract 415 from 433, we get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 83

Step 5:
If we divide 182 by 83, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 652.0
Deduct 166 from 182 and we're left with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 83

On to step 6:
83 goes into 161 1 times with a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 6521.0
If we take 83 away from 161, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 7:
The number 83 fits into 780 9 times, leaving a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 6521.9
If we subtract 747 from 780, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 8:
330 divided by 83 is 3 with a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 6521.93
Deduct 249 from 330 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
When dividing 810 by 83, we get 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 6521.939
If we take 747 away from 810, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 10:
When dividing 630 by 83, we get 7 with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 6521.9397
The remainder is 49 after subtracting 581 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
83 can be fit into 490 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 6521.93975
If we take 415 away from 490, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
The number 83 fits into 750 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 6521.939759
Subtracting 747 from 750 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
83 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6521.939759
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
When dividing 300 by 83, we get 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 6521.93975903
Subtract 249 from 300 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 6521.93975903, with a leftover of 5.1e-08.
