89789372 ÷ 519 
The aim is to understand the frequency of 519 in 89789372.

Let's proceed to step 1:
519 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 519

Going ahead to step 2:
89 divided by 519 is 0 with a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Include the next digit (7) from the dividend after 89, then repeat: 897 / 519

Advancing to step 3:
897 divided by 519 is 1 with a remainder of 378.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 378 after subtracting 519 from 897.
Include the next digit (8) from the dividend after 378, then repeat: 3788 / 519

On to step 4:
519 goes into 3788 7 times with a remainder of 155.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 3633 from 3788 to get 155.
Take the next digit (9) from the dividend and append it to 155, then repeat: 1559 / 519

Going ahead to step 5:
519 can be fit into 1559 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 173.0
If we take 1557 away from 1559, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 519

Step 6:
519 can be fit into 23 0 times, resulting in a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 1730.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 519

Moving on to step 7:
If we divide 237 by 519, we get 0 and a remainder of 237.
Put 0 as the next digit of the answer. 
Result so far: 17300.0
Subtract 0 from 237 to get 237.
Append the next digit (2) from the dividend to 237 and continue with: 2372 / 519

Moving on to step 8:
When dividing 2372 by 519, we get 4 with a remainder of 296.
Put 4 as the next digit of the answer. 
Result so far: 173004.0
Subtracting 2076 from 2372 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 9:
When dividing 2960 by 519, we get 5 with a remainder of 365.
Write down 5 as next digit of the result. 
Result so far: 173004.5
If we subtract 2595 from 2960, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 10:
519 can be fit into 3650 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 173004.57
If we subtract 3633 from 3650, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
519 can be fit into 170 0 times, resulting in a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 173004.57
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 12:
519 goes into 1700 3 times with a remainder of 143.
Write down 3 as next digit of the result. 
Result so far: 173004.5703
Subtract 1557 from 1700 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 13:
If we divide 1430 by 519, we get 2 and a remainder of 392.
Write down 2 as next digit of the result. 
Result so far: 173004.57032
Subtracting 1038 from 1430 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 14:
When dividing 3920 by 519, we get 7 with a remainder of 287.
Record the quotient 7 as the next digit in the result. 
Result so far: 173004.570327
Deduct 3633 from 3920 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Moving on to step 15:
2870 divided by 519 is 5 with a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 173004.5703275
Deduct 2595 from 2870 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 16:
2750 divided by 519 is 5 with a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 173004.57032755
Subtracting 2595 from 2750 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The quotient of the division is 173004.57032755, and the remainder is 1.55e-07.
