77423236 divided by 519 
The aim is to understand the frequency of 519 in 77423236.

Let's proceed to step 1:
If we divide 7 by 519, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 519

Moving on to step 2:
77 divided by 519 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (4) from the dividend and append it to 77, then repeat: 774 / 519

Moving on to step 3:
774 divided by 519 is 1 with a remainder of 255.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 519 from 774 leaves us with 255.
Bring next digit (2) of the dividend behind the 255 and repeat the process: 2552 / 519

Going ahead to step 4:
If we divide 2552 by 519, we get 4 and a remainder of 476.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 2076 from 2552 and we're left with 476.
Grab the next digit (3) from the dividend, add it to 476, then carry on: 4763 / 519

Moving on to step 5:
4763 divided by 519 is 9 with a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 149.0
The remainder is 92 after subtracting 4671 from 4763.
Fetch the next digit (2) from the dividend, attach it to 92 and continue: 922 / 519

Going ahead to step 6:
The number 519 fits into 922 1 times, leaving a remainder of 403.
Record the quotient 1 as the next digit in the result. 
Result so far: 1491.0
Deduct 519 from 922 and we're left with 403.
Fetch the next digit (3) from the dividend, attach it to 403 and continue: 4033 / 519

Going ahead to step 7:
519 goes into 4033 7 times with a remainder of 400.
Write down 7 as next digit of the result. 
Result so far: 14917.0
Subtract 3633 from 4033 to get 400.
Include the next digit (6) from the dividend after 400, then repeat: 4006 / 519

Moving on to step 8:
519 can be fit into 4006 7 times, resulting in a remainder of 373.
The number 7 becomes the next digit in our result. 
Result so far: 149177.0
If we subtract 3633 from 4006, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Step 9:
3730 divided by 519 is 7 with a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 149177.7
The remainder is 97 after subtracting 3633 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 10:
If we divide 970 by 519, we get 1 and a remainder of 451.
Write down 1 as next digit of the result. 
Result so far: 149177.71
If we subtract 519 from 970, we get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

On to step 11:
If we divide 4510 by 519, we get 8 and a remainder of 358.
Put 8 as the next digit of the answer. 
Result so far: 149177.718
The remainder is 358 after subtracting 4152 from 4510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 12:
519 goes into 3580 6 times with a remainder of 466.
The next digit of our result is 6. 
Result so far: 149177.7186
Subtract 3114 from 3580 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 13:
4660 divided by 519 is 8 with a remainder of 508.
Record the quotient 8 as the next digit in the result. 
Result so far: 149177.71868
If we take 4152 away from 4660, we end up with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 14:
5080 divided by 519 is 9 with a remainder of 409.
The number 9 becomes the next digit in our result. 
Result so far: 149177.718689
Deduct 4671 from 5080 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 15:
When dividing 4090 by 519, we get 7 with a remainder of 457.
Record the quotient 7 as the next digit in the result. 
Result so far: 149177.7186897
The remainder is 457 after subtracting 3633 from 4090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Advancing to step 16:
4570 divided by 519 is 8 with a remainder of 418.
Use 8 as the next digit of our solution. 
Result so far: 149177.71868978
If we take 4152 away from 4570, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

After the division, we end up with 149177.71868978 and a remainder of 4.18e-07.
