15285677 ÷ 817 
The aim is to understand the frequency of 817 in 15285677.

Step 1:
The number 817 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 817

Advancing to step 2:
15 divided by 817 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 817

Going ahead to step 3:
The number 817 fits into 152 0 times, leaving a remainder of 152.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 152 after subtracting 0 from 152.
Append the next digit (8) from the dividend to 152 and continue with: 1528 / 817

On to step 4:
1528 divided by 817 is 1 with a remainder of 711.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 817 from 1528 to get 711.
Append the next digit (5) from the dividend to 711 and continue with: 7115 / 817

Going ahead to step 5:
817 can be fit into 7115 8 times, resulting in a remainder of 579.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 6536 from 7115 and we're left with 579.
Include the next digit (6) from the dividend after 579, then repeat: 5796 / 817

On to step 6:
When dividing 5796 by 817, we get 7 with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
The remainder is 77 after subtracting 5719 from 5796.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 817

Advancing to step 7:
817 goes into 777 0 times with a remainder of 777.
Record the quotient 0 as the next digit in the result. 
Result so far: 1870.0
If we subtract 0 from 777, we get 777.
Take the next digit (7) from the dividend and append it to 777, then repeat: 7777 / 817

Advancing to step 8:
817 can be fit into 7777 9 times, resulting in a remainder of 424.
Use 9 as the next digit of our solution. 
Result so far: 18709.0
Subtracting 7353 from 7777 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 9:
When dividing 4240 by 817, we get 5 with a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 18709.5
Subtracting 4085 from 4240 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 10:
The number 817 fits into 1550 1 times, leaving a remainder of 733.
Record the quotient 1 as the next digit in the result. 
Result so far: 18709.51
Deduct 817 from 1550 and we're left with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Going ahead to step 11:
The number 817 fits into 7330 8 times, leaving a remainder of 794.
The next digit of our result is 8. 
Result so far: 18709.518
The remainder is 794 after subtracting 6536 from 7330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

On to step 12:
817 goes into 7940 9 times with a remainder of 587.
Put 9 as the next digit of the answer. 
Result so far: 18709.5189
If we subtract 7353 from 7940, we get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Step 13:
When dividing 5870 by 817, we get 7 with a remainder of 151.
Write down 7 as next digit of the result. 
Result so far: 18709.51897
The remainder is 151 after subtracting 5719 from 5870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 14:
817 goes into 1510 1 times with a remainder of 693.
Record the quotient 1 as the next digit in the result. 
Result so far: 18709.518971
Subtract 817 from 1510 to get 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Moving on to step 15:
817 goes into 6930 8 times with a remainder of 394.
Put 8 as the next digit of the answer. 
Result so far: 18709.5189718
Subtract 6536 from 6930 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 16:
The number 817 fits into 3940 4 times, leaving a remainder of 672.
Put 4 as the next digit of the answer. 
Result so far: 18709.51897184
The remainder is 672 after subtracting 3268 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The final result is 18709.51897184 with a remainder of 6.72e-07.
