64874834 divided by 817 
The aim is to understand the frequency of 817 in 64874834.

On to step 1:
When dividing 6 by 817, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 817

Let's proceed to step 2:
The number 817 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 817

Moving on to step 3:
When dividing 648 by 817, we get 0 with a remainder of 648.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 648 leaves us with 648.
Grab the next digit (7) from the dividend, add it to 648, then carry on: 6487 / 817

Moving on to step 4:
When dividing 6487 by 817, we get 7 with a remainder of 768.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 5719 from 6487 and we're left with 768.
Bring next digit (4) of the dividend behind the 768 and repeat the process: 7684 / 817

Going ahead to step 5:
7684 divided by 817 is 9 with a remainder of 331.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we take 7353 away from 7684, we end up with 331.
Append the next digit (8) from the dividend to 331 and continue with: 3318 / 817

Let's proceed to step 6:
3318 divided by 817 is 4 with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 794.0
If we subtract 3268 from 3318, we get 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 817

Advancing to step 7:
If we divide 503 by 817, we get 0 and a remainder of 503.
Write down 0 as next digit of the result. 
Result so far: 7940.0
Subtracting 0 from 503 leaves us with 503.
Take the next digit (4) from the dividend and append it to 503, then repeat: 5034 / 817

Moving on to step 8:
817 goes into 5034 6 times with a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 79406.0
The remainder is 132 after subtracting 4902 from 5034.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 9:
When dividing 1320 by 817, we get 1 with a remainder of 503.
The next digit of our result is 1. 
Result so far: 79406.1
Subtract 817 from 1320 to get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Advancing to step 10:
817 goes into 5030 6 times with a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 79406.16
The remainder is 128 after subtracting 4902 from 5030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 11:
817 can be fit into 1280 1 times, resulting in a remainder of 463.
Record the quotient 1 as the next digit in the result. 
Result so far: 79406.161
If we take 817 away from 1280, we end up with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Let's proceed to step 12:
If we divide 4630 by 817, we get 5 and a remainder of 545.
Record the quotient 5 as the next digit in the result. 
Result so far: 79406.1615
The remainder is 545 after subtracting 4085 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

On to step 13:
817 can be fit into 5450 6 times, resulting in a remainder of 548.
Put 6 as the next digit of the answer. 
Result so far: 79406.16156
Subtracting 4902 from 5450 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 14:
The number 817 fits into 5480 6 times, leaving a remainder of 578.
Use 6 as the next digit of our solution. 
Result so far: 79406.161566
Subtracting 4902 from 5480 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

The final outcome is 79406.161566, with a leftover of 5.78e-05.
