57769222 divided by 768 
The aim is to understand the frequency of 768 in 57769222.

Advancing to step 1:
5 divided by 768 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 768

On to step 2:
768 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 768

Moving on to step 3:
When dividing 577 by 768, we get 0 with a remainder of 577.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 577 and we're left with 577.
Take the next digit (6) from the dividend and append it to 577, then repeat: 5776 / 768

Advancing to step 4:
When dividing 5776 by 768, we get 7 with a remainder of 400.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 5376 from 5776 and we're left with 400.
Bring next digit (9) of the dividend behind the 400 and repeat the process: 4009 / 768

On to step 5:
When dividing 4009 by 768, we get 5 with a remainder of 169.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtract 3840 from 4009 to get 169.
Fetch the next digit (2) from the dividend, attach it to 169 and continue: 1692 / 768

Step 6:
If we divide 1692 by 768, we get 2 and a remainder of 156.
Record the quotient 2 as the next digit in the result. 
Result so far: 752.0
If we take 1536 away from 1692, we end up with 156.
Take the next digit (2) from the dividend and append it to 156, then repeat: 1562 / 768

On to step 7:
The number 768 fits into 1562 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 7522.0
The remainder is 26 after subtracting 1536 from 1562.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 768

Going ahead to step 8:
The number 768 fits into 262 0 times, leaving a remainder of 262.
Use 0 as the next digit of our solution. 
Result so far: 75220.0
Deduct 0 from 262 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 9:
768 can be fit into 2620 3 times, resulting in a remainder of 316.
The number 3 becomes the next digit in our result. 
Result so far: 75220.3
Subtract 2304 from 2620 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 10:
768 can be fit into 3160 4 times, resulting in a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 75220.34
If we subtract 3072 from 3160, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
If we divide 880 by 768, we get 1 and a remainder of 112.
The next digit of our result is 1. 
Result so far: 75220.341
If we subtract 768 from 880, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 12:
If we divide 1120 by 768, we get 1 and a remainder of 352.
Write down 1 as next digit of the result. 
Result so far: 75220.3411
If we take 768 away from 1120, we end up 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.

After the division, we end up with 75220.3411 and a remainder of 0.00352.
