345144 ÷ 83 
The aim is to understand the frequency of 83 in 345144.

Step 1:
The number 83 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 83

Step 2:
If we divide 34 by 83, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 83

On to step 3:
The number 83 fits into 345 4 times, leaving a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 13 after subtracting 332 from 345.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 83

On to step 4:
If we divide 131 by 83, we get 1 and a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 48 after subtracting 83 from 131.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 83

Moving on to step 5:
83 goes into 484 5 times with a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 415.0
The remainder is 69 after subtracting 415 from 484.
Fetch the next digit (4) from the dividend, attach it to 69 and continue: 694 / 83

Advancing to step 6:
If we divide 694 by 83, we get 8 and a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 4158.0
Subtract 664 from 694 to get 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 7:
83 can be fit into 300 3 times, resulting in a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 4158.3
The remainder is 51 after subtracting 249 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
83 goes into 510 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 4158.36
Deduct 498 from 510 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
83 can be fit into 120 1 times, resulting in a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 4158.361
If we subtract 83 from 120, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 10:
The number 83 fits into 370 4 times, leaving a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 4158.3614
Deduct 332 from 370 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
380 divided by 83 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 4158.36144
Deduct 332 from 380 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 4158.36144 and a remainder of 4.8e-05.
