120105 ÷ 83 
The aim is to understand the frequency of 83 in 120105.

On to step 1:
When dividing 1 by 83, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 83

Moving on to step 2:
83 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 83

Step 3:
When dividing 120 by 83, we get 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 83 from 120 and we're left with 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 83

Moving on to step 4:
83 can be fit into 371 4 times, resulting in a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 332 from 371 and we're left with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 83

Moving on to step 5:
The number 83 fits into 390 4 times, leaving a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
If we take 332 away from 390, we end up with 58.
Append the next digit (5) from the dividend to 58 and continue with: 585 / 83

Moving on to step 6:
If we divide 585 by 83, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 1447.0
Deduct 581 from 585 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
83 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1447.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 83 fits into 400 4 times, leaving a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 1447.04
Subtract 332 from 400 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
When dividing 680 by 83, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1447.048
If we subtract 664 from 680, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
83 goes into 160 1 times with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 1447.0481
If we subtract 83 from 160, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 11:
770 divided by 83 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 1447.04819
Subtracting 747 from 770 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
230 divided by 83 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 1447.048192
The remainder is 64 after subtracting 166 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
640 divided by 83 is 7 with a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 1447.0481927
Subtracting 581 from 640 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 14:
83 goes into 590 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 1447.04819277
Subtracting 581 from 590 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 1447.04819277 with a remaining 9e-09.
