78519682 ÷ 456 
The aim is to understand the frequency of 456 in 78519682.

Advancing to step 1:
456 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 456

Step 2:
78 divided by 456 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 456

Step 3:
456 can be fit into 785 1 times, resulting in a remainder of 329.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 456 from 785 leaves us with 329.
Append the next digit (1) from the dividend to 329 and continue with: 3291 / 456

Let's proceed to step 4:
When dividing 3291 by 456, we get 7 with a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 3192 from 3291, we get 99.
Take the next digit (9) from the dividend and append it to 99, then repeat: 999 / 456

Advancing to step 5:
If we divide 999 by 456, we get 2 and a remainder of 87.
Write down 2 as next digit of the result. 
Result so far: 172.0
The remainder is 87 after subtracting 912 from 999.
Grab the next digit (6) from the dividend, add it to 87, then carry on: 876 / 456

Moving on to step 6:
456 goes into 876 1 times with a remainder of 420.
The next digit of our result is 1. 
Result so far: 1721.0
Subtract 456 from 876 to get 420.
Grab the next digit (8) from the dividend, add it to 420, then carry on: 4208 / 456

Moving on to step 7:
If we divide 4208 by 456, we get 9 and a remainder of 104.
The number 9 becomes the next digit in our result. 
Result so far: 17219.0
Subtract 4104 from 4208 to get 104.
Take the next digit (2) from the dividend and append it to 104, then repeat: 1042 / 456

Let's proceed to step 8:
The number 456 fits into 1042 2 times, leaving a remainder of 130.
Record the quotient 2 as the next digit in the result. 
Result so far: 172192.0
If we subtract 912 from 1042, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 9:
When dividing 1300 by 456, we get 2 with a remainder of 388.
The next digit of our result is 2. 
Result so far: 172192.2
If we take 912 away from 1300, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 10:
When dividing 3880 by 456, we get 8 with a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 172192.28
If we subtract 3648 from 3880, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 11:
When dividing 2320 by 456, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 172192.285
Deduct 2280 from 2320 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
The number 456 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 172192.285
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
4000 divided by 456 is 8 with a remainder of 352.
The next digit of our result is 8. 
Result so far: 172192.28508
Deduct 3648 from 4000 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 14:
456 goes into 3520 7 times with a remainder of 328.
Write down 7 as next digit of the result. 
Result so far: 172192.285087
Subtracting 3192 from 3520 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 15:
3280 divided by 456 is 7 with a remainder of 88.
Put 7 as the next digit of the answer. 
Result so far: 172192.2850877
Deduct 3192 from 3280 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 172192.2850877 and a remainder of 8.8e-07.
