We look at the division of 67437981 by 768 
The aim is to understand the frequency of 768 in 67437981.

Going ahead to step 1:
768 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 768

Going ahead to step 2:
If we divide 67 by 768, we get 0 and a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 768

On to step 3:
If we divide 674 by 768, we get 0 and a remainder of 674.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 674 after subtracting 0 from 674.
Take the next digit (3) from the dividend and append it to 674, then repeat: 6743 / 768

Let's proceed to step 4:
When dividing 6743 by 768, we get 8 with a remainder of 599.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6144 away from 6743, we end up with 599.
Take the next digit (7) from the dividend and append it to 599, then repeat: 5997 / 768

On to step 5:
5997 divided by 768 is 7 with a remainder of 621.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtracting 5376 from 5997 leaves us with 621.
Append the next digit (9) from the dividend to 621 and continue with: 6219 / 768

Advancing to step 6:
768 can be fit into 6219 8 times, resulting in a remainder of 75.
Put 8 as the next digit of the answer. 
Result so far: 878.0
Subtracting 6144 from 6219 leaves us with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 768

Let's proceed to step 7:
768 can be fit into 758 0 times, resulting in a remainder of 758.
Put 0 as the next digit of the answer. 
Result so far: 8780.0
Subtract 0 from 758 to get 758.
Append the next digit (1) from the dividend to 758 and continue with: 7581 / 768

Going ahead to step 8:
The number 768 fits into 7581 9 times, leaving a remainder of 669.
Use 9 as the next digit of our solution. 
Result so far: 87809.0
Deduct 6912 from 7581 and we're left with 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

On to step 9:
When dividing 6690 by 768, we get 8 with a remainder of 546.
Record the quotient 8 as the next digit in the result. 
Result so far: 87809.8
Subtract 6144 from 6690 to get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Going ahead to step 10:
5460 divided by 768 is 7 with a remainder of 84.
The next digit of our result is 7. 
Result so far: 87809.87
If we subtract 5376 from 5460, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 11:
768 can be fit into 840 1 times, resulting in a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 87809.871
If we subtract 768 from 840, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
The number 768 fits into 720 0 times, leaving a remainder of 720.
Use 0 as the next digit of our solution. 
Result so far: 87809.871
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 13:
The number 768 fits into 7200 9 times, leaving a remainder of 288.
Use 9 as the next digit of our solution. 
Result so far: 87809.87109
The remainder is 288 after subtracting 6912 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 14:
768 goes into 2880 3 times with a remainder of 576.
Record the quotient 3 as the next digit in the result. 
Result so far: 87809.871093
Deduct 2304 from 2880 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 15:
When dividing 5760 by 768, we get 7 with a remainder of 384.
Put 7 as the next digit of the answer. 
Result so far: 87809.8710937
Subtracting 5376 from 5760 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 16:
3840 divided by 768 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 87809.87109375
If we take 3840 away from 3840, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 87809.87109375 and a remainder of 0.0.
