64992005 ÷ 863 
The aim is to understand the frequency of 863 in 64992005.

Step 1:
863 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 863

Step 2:
If we divide 64 by 863, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 863

Let's proceed to step 3:
If we divide 649 by 863, we get 0 and a remainder of 649.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 649 leaves us with 649.
Include the next digit (9) from the dividend after 649, then repeat: 6499 / 863

Going ahead to step 4:
If we divide 6499 by 863, we get 7 and a remainder of 458.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 458 after subtracting 6041 from 6499.
Append the next digit (2) from the dividend to 458 and continue with: 4582 / 863

On to step 5:
If we divide 4582 by 863, we get 5 and a remainder of 267.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 4315 from 4582, we get 267.
Fetch the next digit (0) from the dividend, attach it to 267 and continue: 2670 / 863

Going ahead to step 6:
863 goes into 2670 3 times with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 753.0
Subtract 2589 from 2670 to get 81.
Include the next digit (0) from the dividend after 81, then repeat: 810 / 863

Let's proceed to step 7:
When dividing 810 by 863, we get 0 with a remainder of 810.
The number 0 becomes the next digit in our result. 
Result so far: 7530.0
Subtract 0 from 810 to get 810.
Grab the next digit (5) from the dividend, add it to 810, then carry on: 8105 / 863

Going ahead to step 8:
863 can be fit into 8105 9 times, resulting in a remainder of 338.
Record the quotient 9 as the next digit in the result. 
Result so far: 75309.0
If we subtract 7767 from 8105, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 9:
3380 divided by 863 is 3 with a remainder of 791.
Put 3 as the next digit of the answer. 
Result so far: 75309.3
Deduct 2589 from 3380 and we're left with 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Let's proceed to step 10:
If we divide 7910 by 863, we get 9 and a remainder of 143.
The next digit of our result is 9. 
Result so far: 75309.39
Deduct 7767 from 7910 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 11:
The number 863 fits into 1430 1 times, leaving a remainder of 567.
Put 1 as the next digit of the answer. 
Result so far: 75309.391
Deduct 863 from 1430 and we're left with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 12:
If we divide 5670 by 863, we get 6 and a remainder of 492.
Use 6 as the next digit of our solution. 
Result so far: 75309.3916
Deduct 5178 from 5670 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Advancing to step 13:
The number 863 fits into 4920 5 times, leaving a remainder of 605.
Use 5 as the next digit of our solution. 
Result so far: 75309.39165
If we subtract 4315 from 4920, we get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Going ahead to step 14:
If we divide 6050 by 863, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 75309.391657
Deduct 6041 from 6050 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 15:
If we divide 90 by 863, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 75309.391657
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 16:
The number 863 fits into 900 1 times, leaving a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 75309.39165701
Subtract 863 from 900 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 75309.39165701, with a leftover of 3.7e-08.
