83872 divided by 83 
The aim is to understand the frequency of 83 in 83872.

Moving on to step 1:
83 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 83

Advancing to step 2:
83 goes into 83 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 83 from 83 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 83

On to step 3:
When dividing 8 by 83, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 83

Step 4:
87 divided by 83 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Deduct 83 from 87 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 83

Advancing to step 5:
83 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 1010.0
The remainder is 42 after subtracting 0 from 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 6:
If we divide 420 by 83, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1010.5
Subtracting 415 from 420 leaves us 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.

Advancing to step 7:
83 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 1010.5
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
When dividing 500 by 83, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 1010.506
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.

Going ahead to step 9:
83 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1010.506
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
83 goes into 200 2 times with a remainder of 34.
The next digit of our result is 2. 
Result so far: 1010.50602
Deduct 166 from 200 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
83 can be fit into 340 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1010.506024
Deduct 332 from 340 and we're left 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.

Going ahead to step 12:
When dividing 80 by 83, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 1010.506024
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
83 goes into 800 9 times with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 1010.50602409
Subtracting 747 from 800 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The quotient of the division is 1010.50602409, and the remainder is 5.3e-08.
