872883 ÷ 83 
The aim is to understand the frequency of 83 in 872883.

On to step 1:
The number 83 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 83

Going ahead to step 2:
83 can be fit into 87 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 83 from 87 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 83

On to step 3:
83 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 83

Step 4:
The number 83 fits into 428 5 times, leaving a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtract 415 from 428 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 83

Step 5:
83 goes into 138 1 times with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 1051.0
Deduct 83 from 138 and we're left with 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 83

Step 6:
553 divided by 83 is 6 with a remainder of 55.
Use 6 as the next digit of our solution. 
Result so far: 10516.0
The remainder is 55 after subtracting 498 from 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
550 divided by 83 is 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 10516.6
Subtracting 498 from 550 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
520 divided by 83 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 10516.66
The remainder is 22 after subtracting 498 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 10516.66 and a remainder of 0.022.
