Let's divide 91278422 by 519
The aim is to understand the frequency of 519 in 91278422.

Advancing to step 1:
The number 519 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 519

Step 2:
When dividing 91 by 519, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (2) from the dividend and append it to 91, then repeat: 912 / 519

Going ahead to step 3:
519 can be fit into 912 1 times, resulting in a remainder of 393.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 519 from 912, we get 393.
Bring next digit (7) of the dividend behind the 393 and repeat the process: 3937 / 519

Let's proceed to step 4:
519 goes into 3937 7 times with a remainder of 304.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 3633 from 3937 to get 304.
Append the next digit (8) from the dividend to 304 and continue with: 3048 / 519

Let's proceed to step 5:
If we divide 3048 by 519, we get 5 and a remainder of 453.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
Deduct 2595 from 3048 and we're left with 453.
Fetch the next digit (4) from the dividend, attach it to 453 and continue: 4534 / 519

Going ahead to step 6:
The number 519 fits into 4534 8 times, leaving a remainder of 382.
Write down 8 as next digit of the result. 
Result so far: 1758.0
If we subtract 4152 from 4534, we get 382.
Include the next digit (2) from the dividend after 382, then repeat: 3822 / 519

Step 7:
When dividing 3822 by 519, we get 7 with a remainder of 189.
Record the quotient 7 as the next digit in the result. 
Result so far: 17587.0
Deduct 3633 from 3822 and we're left with 189.
Append the next digit (2) from the dividend to 189 and continue with: 1892 / 519

Step 8:
If we divide 1892 by 519, we get 3 and a remainder of 335.
Write down 3 as next digit of the result. 
Result so far: 175873.0
Subtracting 1557 from 1892 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 9:
3350 divided by 519 is 6 with a remainder of 236.
Record the quotient 6 as the next digit in the result. 
Result so far: 175873.6
The remainder is 236 after subtracting 3114 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 10:
When dividing 2360 by 519, we get 4 with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 175873.64
Subtracting 2076 from 2360 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 11:
2840 divided by 519 is 5 with a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 175873.645
Deduct 2595 from 2840 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 12:
If we divide 2450 by 519, we get 4 and a remainder of 374.
The number 4 becomes the next digit in our result. 
Result so far: 175873.6454
If we take 2076 away from 2450, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 13:
The number 519 fits into 3740 7 times, leaving a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 175873.64547
If we subtract 3633 from 3740, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 14:
When dividing 1070 by 519, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 175873.645472
If we subtract 1038 from 1070, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 15:
519 goes into 320 0 times with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 175873.645472
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 16:
519 can be fit into 3200 6 times, resulting in a remainder of 86.
The next digit of our result is 6. 
Result so far: 175873.64547206
If we take 3114 away from 3200, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 175873.64547206, with a leftover of 8.6e-08.
