We look at the division of 60771919 by 748 
The aim is to understand the frequency of 748 in 60771919.

Going ahead to step 1:
6 divided by 748 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 748

Advancing to step 2:
60 divided by 748 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 748

Advancing to step 3:
748 can be fit into 607 0 times, resulting in a remainder of 607.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 607 leaves us with 607.
Fetch the next digit (7) from the dividend, attach it to 607 and continue: 6077 / 748

Let's proceed to step 4:
6077 divided by 748 is 8 with a remainder of 93.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 5984 from 6077 and we're left with 93.
Fetch the next digit (1) from the dividend, attach it to 93 and continue: 931 / 748

On to step 5:
When dividing 931 by 748, we get 1 with a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we subtract 748 from 931, we get 183.
Append the next digit (9) from the dividend to 183 and continue with: 1839 / 748

Advancing to step 6:
If we divide 1839 by 748, we get 2 and a remainder of 343.
The number 2 becomes the next digit in our result. 
Result so far: 812.0
Deduct 1496 from 1839 and we're left with 343.
Include the next digit (1) from the dividend after 343, then repeat: 3431 / 748

Moving on to step 7:
The number 748 fits into 3431 4 times, leaving a remainder of 439.
Write down 4 as next digit of the result. 
Result so far: 8124.0
Subtract 2992 from 3431 to get 439.
Grab the next digit (9) from the dividend, add it to 439, then carry on: 4399 / 748

Advancing to step 8:
The number 748 fits into 4399 5 times, leaving a remainder of 659.
Use 5 as the next digit of our solution. 
Result so far: 81245.0
If we take 3740 away from 4399, we end up with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Moving on to step 9:
When dividing 6590 by 748, we get 8 with a remainder of 606.
Put 8 as the next digit of the answer. 
Result so far: 81245.8
If we take 5984 away from 6590, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Step 10:
748 can be fit into 6060 8 times, resulting in a remainder of 76.
The next digit of our result is 8. 
Result so far: 81245.88
Subtract 5984 from 6060 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 81245.88 with a remainder of 0.076.
