50646792 ÷ 819 
The aim is to understand the frequency of 819 in 50646792.

Let's proceed to step 1:
5 divided by 819 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 819

On to step 2:
819 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 819

Step 3:
The number 819 fits into 506 0 times, leaving a remainder of 506.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 506, we get 506.
Fetch the next digit (4) from the dividend, attach it to 506 and continue: 5064 / 819

Step 4:
The number 819 fits into 5064 6 times, leaving a remainder of 150.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 4914 from 5064 and we're left with 150.
Include the next digit (6) from the dividend after 150, then repeat: 1506 / 819

Advancing to step 5:
When dividing 1506 by 819, we get 1 with a remainder of 687.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we subtract 819 from 1506, we get 687.
Include the next digit (7) from the dividend after 687, then repeat: 6877 / 819

Going ahead to step 6:
When dividing 6877 by 819, we get 8 with a remainder of 325.
Put 8 as the next digit of the answer. 
Result so far: 618.0
If we subtract 6552 from 6877, we get 325.
Grab the next digit (9) from the dividend, add it to 325, then carry on: 3259 / 819

Advancing to step 7:
819 goes into 3259 3 times with a remainder of 802.
Write down 3 as next digit of the result. 
Result so far: 6183.0
Deduct 2457 from 3259 and we're left with 802.
Take the next digit (2) from the dividend and append it to 802, then repeat: 8022 / 819

Step 8:
8022 divided by 819 is 9 with a remainder of 651.
The number 9 becomes the next digit in our result. 
Result so far: 61839.0
If we subtract 7371 from 8022, we get 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Advancing to step 9:
819 goes into 6510 7 times with a remainder of 777.
The number 7 becomes the next digit in our result. 
Result so far: 61839.7
If we subtract 5733 from 6510, we get 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Going ahead to step 10:
The number 819 fits into 7770 9 times, leaving a remainder of 399.
Write down 9 as next digit of the result. 
Result so far: 61839.79
Subtract 7371 from 7770 to get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 11:
3990 divided by 819 is 4 with a remainder of 714.
Record the quotient 4 as the next digit in the result. 
Result so far: 61839.794
The remainder is 714 after subtracting 3276 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Moving on to step 12:
819 goes into 7140 8 times with a remainder of 588.
The next digit of our result is 8. 
Result so far: 61839.7948
If we subtract 6552 from 7140, we get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 13:
819 can be fit into 5880 7 times, resulting in a remainder of 147.
Use 7 as the next digit of our solution. 
Result so far: 61839.79487
Deduct 5733 from 5880 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 14:
819 can be fit into 1470 1 times, resulting in a remainder of 651.
Record the quotient 1 as the next digit in the result. 
Result so far: 61839.794871
Subtracting 819 from 1470 leaves us with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Let's proceed to step 15:
819 can be fit into 6510 7 times, resulting in a remainder of 777.
Record the quotient 7 as the next digit in the result. 
Result so far: 61839.7948717
If we take 5733 away from 6510, we end up with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Going ahead to step 16:
If we divide 7770 by 819, we get 9 and a remainder of 399.
Write down 9 as next digit of the result. 
Result so far: 61839.79487179
Subtracting 7371 from 7770 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

After the division, we end up with 61839.79487179 and a remainder of 3.99e-07.
