Let's divide 872188 by 83
The aim is to understand the frequency of 83 in 872188.

On to step 1:
When dividing 8 by 83, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 83

Step 2:
83 goes into 87 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 4 after subtracting 83 from 87.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 83

Let's proceed to step 3:
When dividing 42 by 83, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 83

Step 4:
83 can be fit into 421 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 105.0
If we take 415 away from 421, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 83

Let's proceed to step 5:
When dividing 68 by 83, we get 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 1050.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (8) from the dividend to 68 and continue with: 688 / 83

Going ahead to step 6:
83 goes into 688 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 10508.0
If we take 664 away from 688, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
The number 83 fits into 240 2 times, leaving a remainder of 74.
The next digit of our result is 2. 
Result so far: 10508.2
If we subtract 166 from 240, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 8:
When dividing 740 by 83, we get 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 10508.28
Subtracting 664 from 740 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
83 can be fit into 760 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 10508.289
If we subtract 747 from 760, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
83 can be fit into 130 1 times, resulting in a remainder of 47.
The next digit of our result is 1. 
Result so far: 10508.2891
Deduct 83 from 130 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 11:
When dividing 470 by 83, we get 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 10508.28915
Subtract 415 from 470 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
When dividing 550 by 83, we get 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 10508.289156
If we take 498 away from 550, we end up 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.

Advancing to step 13:
The number 83 fits into 520 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 10508.2891566
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.

Our division results in 10508.2891566 with a remaining 2.2e-07.
