450670 ÷ 83 
The aim is to understand the frequency of 83 in 450670.

On to step 1:
The number 83 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 83

Moving on to step 2:
83 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 83

Moving on to step 3:
450 divided by 83 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 415 from 450 leaves us with 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 83

Step 4:
The number 83 fits into 356 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 332 from 356 to get 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 83

Moving on to step 5:
83 goes into 247 2 times with a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 542.0
Subtracting 166 from 247 leaves us with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 83

Moving on to step 6:
When dividing 810 by 83, we get 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 5429.0
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 7:
When dividing 630 by 83, we get 7 with a remainder of 49.
The next digit of our result is 7. 
Result so far: 5429.7
Subtracting 581 from 630 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
490 divided by 83 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 5429.75
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 9:
If we divide 750 by 83, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 5429.759
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.

Step 10:
When dividing 30 by 83, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5429.759
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
When dividing 300 by 83, we get 3 with a remainder of 51.
The next digit of our result is 3. 
Result so far: 5429.75903
Deduct 249 from 300 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 12:
The number 83 fits into 510 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 5429.759036
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.

Going ahead to step 13:
The number 83 fits into 120 1 times, leaving a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 5429.7590361
The remainder is 37 after subtracting 83 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 14:
83 can be fit into 370 4 times, resulting in a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 5429.75903614
If we subtract 332 from 370, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 5429.75903614, with a leftover of 3.8e-08.
