51381358 ÷ 768 
The aim is to understand the frequency of 768 in 51381358.

Moving on to step 1:
768 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 768

Step 2:
When dividing 51 by 768, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 768

On to step 3:
The number 768 fits into 513 0 times, leaving a remainder of 513.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 513 and we're left with 513.
Take the next digit (8) from the dividend and append it to 513, then repeat: 5138 / 768

Going ahead to step 4:
768 can be fit into 5138 6 times, resulting in a remainder of 530.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 4608 from 5138 leaves us with 530.
Grab the next digit (1) from the dividend, add it to 530, then carry on: 5301 / 768

On to step 5:
5301 divided by 768 is 6 with a remainder of 693.
Write down 6 as next digit of the result. 
Result so far: 66.0
Deduct 4608 from 5301 and we're left with 693.
Fetch the next digit (3) from the dividend, attach it to 693 and continue: 6933 / 768

On to step 6:
The number 768 fits into 6933 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 669.0
If we take 6912 away from 6933, we end up with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 768

Going ahead to step 7:
215 divided by 768 is 0 with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 6690.0
If we subtract 0 from 215, we get 215.
Grab the next digit (8) from the dividend, add it to 215, then carry on: 2158 / 768

Moving on to step 8:
2158 divided by 768 is 2 with a remainder of 622.
The next digit of our result is 2. 
Result so far: 66902.0
Subtract 1536 from 2158 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Advancing to step 9:
When dividing 6220 by 768, we get 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 66902.8
The remainder is 76 after subtracting 6144 from 6220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
760 divided by 768 is 0 with a remainder of 760.
Put 0 as the next digit of the answer. 
Result so far: 66902.8
If we take 0 away from 760, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 11:
When dividing 7600 by 768, we get 9 with a remainder of 688.
Record the quotient 9 as the next digit in the result. 
Result so far: 66902.809
Subtracting 6912 from 7600 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 12:
768 can be fit into 6880 8 times, resulting in a remainder of 736.
Record the quotient 8 as the next digit in the result. 
Result so far: 66902.8098
Deduct 6144 from 6880 and we're left with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 13:
768 can be fit into 7360 9 times, resulting in a remainder of 448.
The number 9 becomes the next digit in our result. 
Result so far: 66902.80989
Deduct 6912 from 7360 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 14:
768 goes into 4480 5 times with a remainder of 640.
Record the quotient 5 as the next digit in the result. 
Result so far: 66902.809895
Subtract 3840 from 4480 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 15:
768 goes into 6400 8 times with a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 66902.8098958
If we take 6144 away from 6400, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 16:
When dividing 2560 by 768, we get 3 with a remainder of 256.
Put 3 as the next digit of the answer. 
Result so far: 66902.80989583
If we subtract 2304 from 2560, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

In conclusion, the division gives 66902.80989583 with a balance of 2.56e-07.
