We look at the division of 344953 by 83 
The aim is to understand the frequency of 83 in 344953.

Going ahead to step 1:
The number 83 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 83

Advancing to step 2:
34 divided by 83 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 83

Advancing to step 3:
If we divide 344 by 83, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 12 after subtracting 332 from 344.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 83

Step 4:
83 can be fit into 129 1 times, resulting in a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 83 from 129 to get 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 83

Advancing to step 5:
83 can be fit into 465 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 415.0
If we take 415 away from 465, we end up with 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 83

Advancing to step 6:
If we divide 503 by 83, we get 6 and a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 4156.0
If we take 498 away from 503, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
83 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4156.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
When dividing 500 by 83, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 4156.06
Subtracting 498 from 500 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
83 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: 4156.06
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
When dividing 200 by 83, we get 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 4156.0602
If we subtract 166 from 200, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
340 divided by 83 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4156.06024
If we take 332 away from 340, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
83 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 4156.06024
Subtracting 0 from 80 leaves us 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.

Advancing to step 13:
The number 83 fits into 800 9 times, leaving a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 4156.0602409
The remainder is 53 after subtracting 747 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 14:
When dividing 530 by 83, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 4156.06024096
Subtracting 498 from 530 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 4156.06024096 with a remainder of 3.2e-08.
