We're dividing 50699511 by 819 
The aim is to understand the frequency of 819 in 50699511.

Step 1:
819 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 819

Step 2:
If we divide 50 by 819, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 819

Going ahead to step 3:
506 divided by 819 is 0 with a remainder of 506.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 506 after subtracting 0 from 506.
Append the next digit (9) from the dividend to 506 and continue with: 5069 / 819

Step 4:
The number 819 fits into 5069 6 times, leaving a remainder of 155.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 4914 away from 5069, we end up with 155.
Append the next digit (9) from the dividend to 155 and continue with: 1559 / 819

Let's proceed to step 5:
When dividing 1559 by 819, we get 1 with a remainder of 740.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we take 819 away from 1559, we end up with 740.
Bring next digit (5) of the dividend behind the 740 and repeat the process: 7405 / 819

On to step 6:
7405 divided by 819 is 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 619.0
The remainder is 34 after subtracting 7371 from 7405.
Include the next digit (1) from the dividend after 34, then repeat: 341 / 819

Step 7:
341 divided by 819 is 0 with a remainder of 341.
Write down 0 as next digit of the result. 
Result so far: 6190.0
Deduct 0 from 341 and we're left with 341.
Grab the next digit (1) from the dividend, add it to 341, then carry on: 3411 / 819

Let's proceed to step 8:
The number 819 fits into 3411 4 times, leaving a remainder of 135.
Record the quotient 4 as the next digit in the result. 
Result so far: 61904.0
The remainder is 135 after subtracting 3276 from 3411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
If we divide 1350 by 819, we get 1 and a remainder of 531.
Put 1 as the next digit of the answer. 
Result so far: 61904.1
Deduct 819 from 1350 and we're left with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 10:
The number 819 fits into 5310 6 times, leaving a remainder of 396.
Record the quotient 6 as the next digit in the result. 
Result so far: 61904.16
If we take 4914 away from 5310, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 11:
If we divide 3960 by 819, we get 4 and a remainder of 684.
Use 4 as the next digit of our solution. 
Result so far: 61904.164
If we take 3276 away from 3960, we end up with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 12:
The number 819 fits into 6840 8 times, leaving a remainder of 288.
The next digit of our result is 8. 
Result so far: 61904.1648
The remainder is 288 after subtracting 6552 from 6840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 13:
The number 819 fits into 2880 3 times, leaving a remainder of 423.
The number 3 becomes the next digit in our result. 
Result so far: 61904.16483
If we subtract 2457 from 2880, we get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Moving on to step 14:
819 goes into 4230 5 times with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 61904.164835
Deduct 4095 from 4230 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 15:
819 goes into 1350 1 times with a remainder of 531.
Use 1 as the next digit of our solution. 
Result so far: 61904.1648351
Subtract 819 from 1350 to get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 16:
When dividing 5310 by 819, we get 6 with a remainder of 396.
Write down 6 as next digit of the result. 
Result so far: 61904.16483516
Subtract 4914 from 5310 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Our division results in 61904.16483516 with a remaining 3.96e-07.
