We look at the division of 48345378 by 751 
The aim is to understand the frequency of 751 in 48345378.

Step 1:
When dividing 4 by 751, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 751

Step 2:
The number 751 fits into 48 0 times, leaving a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Take the next digit (3) from the dividend and append it to 48, then repeat: 483 / 751

Advancing to step 3:
483 divided by 751 is 0 with a remainder of 483.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 483, we end up with 483.
Take the next digit (4) from the dividend and append it to 483, then repeat: 4834 / 751

Going ahead to step 4:
The number 751 fits into 4834 6 times, leaving a remainder of 328.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 4506 away from 4834, we end up with 328.
Fetch the next digit (5) from the dividend, attach it to 328 and continue: 3285 / 751

On to step 5:
When dividing 3285 by 751, we get 4 with a remainder of 281.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 3004 from 3285 leaves us with 281.
Bring next digit (3) of the dividend behind the 281 and repeat the process: 2813 / 751

On to step 6:
2813 divided by 751 is 3 with a remainder of 560.
Put 3 as the next digit of the answer. 
Result so far: 643.0
If we subtract 2253 from 2813, we get 560.
Append the next digit (7) from the dividend to 560 and continue with: 5607 / 751

Advancing to step 7:
When dividing 5607 by 751, we get 7 with a remainder of 350.
The number 7 becomes the next digit in our result. 
Result so far: 6437.0
Subtract 5257 from 5607 to get 350.
Append the next digit (8) from the dividend to 350 and continue with: 3508 / 751

Step 8:
751 goes into 3508 4 times with a remainder of 504.
The number 4 becomes the next digit in our result. 
Result so far: 64374.0
If we take 3004 away from 3508, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 9:
The number 751 fits into 5040 6 times, leaving a remainder of 534.
The next digit of our result is 6. 
Result so far: 64374.6
Deduct 4506 from 5040 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 10:
751 goes into 5340 7 times with a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 64374.67
Subtract 5257 from 5340 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 11:
830 divided by 751 is 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 64374.671
Subtract 751 from 830 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 12:
The number 751 fits into 790 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 64374.6711
Subtract 751 from 790 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 64374.6711, and the remainder is 0.00039.
