124870 divided by 817 
The aim is to understand the frequency of 817 in 124870.

Going ahead to step 1:
If we divide 1 by 817, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 817

Advancing to step 2:
817 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 817

Step 3:
If we divide 124 by 817, we get 0 and a remainder of 124.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Grab the next digit (8) from the dividend, add it to 124, then carry on: 1248 / 817

Moving on to step 4:
817 goes into 1248 1 times with a remainder of 431.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 817 from 1248 and we're left with 431.
Grab the next digit (7) from the dividend, add it to 431, then carry on: 4317 / 817

On to step 5:
The number 817 fits into 4317 5 times, leaving a remainder of 232.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 232 after subtracting 4085 from 4317.
Grab the next digit (0) from the dividend, add it to 232, then carry on: 2320 / 817

On to step 6:
If we divide 2320 by 817, we get 2 and a remainder of 686.
The next digit of our result is 2. 
Result so far: 152.0
Deduct 1634 from 2320 and we're left with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Step 7:
817 can be fit into 6860 8 times, resulting in a remainder of 324.
Use 8 as the next digit of our solution. 
Result so far: 152.8
Subtracting 6536 from 6860 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 8:
If we divide 3240 by 817, we get 3 and a remainder of 789.
Record the quotient 3 as the next digit in the result. 
Result so far: 152.83
Subtracting 2451 from 3240 leaves us with 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Let's proceed to step 9:
7890 divided by 817 is 9 with a remainder of 537.
Record the quotient 9 as the next digit in the result. 
Result so far: 152.839
If we take 7353 away from 7890, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Step 10:
When dividing 5370 by 817, we get 6 with a remainder of 468.
Put 6 as the next digit of the answer. 
Result so far: 152.8396
Subtract 4902 from 5370 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 11:
If we divide 4680 by 817, we get 5 and a remainder of 595.
Use 5 as the next digit of our solution. 
Result so far: 152.83965
Subtract 4085 from 4680 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 12:
When dividing 5950 by 817, we get 7 with a remainder of 231.
Write down 7 as next digit of the result. 
Result so far: 152.839657
Subtract 5719 from 5950 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 13:
2310 divided by 817 is 2 with a remainder of 676.
Put 2 as the next digit of the answer. 
Result so far: 152.8396572
The remainder is 676 after subtracting 1634 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Moving on to step 14:
817 can be fit into 6760 8 times, resulting in a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 152.83965728
The remainder is 224 after subtracting 6536 from 6760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

In conclusion, the division gives 152.83965728 with a balance of 2.24e-07.
