We look at the division of 54874812 by 756 
The aim is to understand the frequency of 756 in 54874812.

On to step 1:
The number 756 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 756

Moving on to step 2:
When dividing 54 by 756, we get 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 756

Going ahead to step 3:
When dividing 548 by 756, we get 0 with a remainder of 548.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 548 after subtracting 0 from 548.
Append the next digit (7) from the dividend to 548 and continue with: 5487 / 756

Let's proceed to step 4:
The number 756 fits into 5487 7 times, leaving a remainder of 195.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 5292 from 5487 to get 195.
Bring next digit (4) of the dividend behind the 195 and repeat the process: 1954 / 756

Moving on to step 5:
756 goes into 1954 2 times with a remainder of 442.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we subtract 1512 from 1954, we get 442.
Append the next digit (8) from the dividend to 442 and continue with: 4428 / 756

Step 6:
The number 756 fits into 4428 5 times, leaving a remainder of 648.
Record the quotient 5 as the next digit in the result. 
Result so far: 725.0
Deduct 3780 from 4428 and we're left with 648.
Fetch the next digit (1) from the dividend, attach it to 648 and continue: 6481 / 756

On to step 7:
If we divide 6481 by 756, we get 8 and a remainder of 433.
Record the quotient 8 as the next digit in the result. 
Result so far: 7258.0
The remainder is 433 after subtracting 6048 from 6481.
Grab the next digit (2) from the dividend, add it to 433, then carry on: 4332 / 756

Step 8:
The number 756 fits into 4332 5 times, leaving a remainder of 552.
The number 5 becomes the next digit in our result. 
Result so far: 72585.0
If we subtract 3780 from 4332, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 9:
5520 divided by 756 is 7 with a remainder of 228.
Write down 7 as next digit of the result. 
Result so far: 72585.7
Subtracting 5292 from 5520 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 10:
When dividing 2280 by 756, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 72585.73
Deduct 2268 from 2280 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
756 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 72585.73
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
756 goes into 1200 1 times with a remainder of 444.
Put 1 as the next digit of the answer. 
Result so far: 72585.7301
If we take 756 away from 1200, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 13:
If we divide 4440 by 756, we get 5 and a remainder of 660.
Record the quotient 5 as the next digit in the result. 
Result so far: 72585.73015
Subtract 3780 from 4440 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 14:
756 goes into 6600 8 times with a remainder of 552.
The next digit of our result is 8. 
Result so far: 72585.730158
Subtracting 6048 from 6600 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 15:
If we divide 5520 by 756, we get 7 and a remainder of 228.
Record the quotient 7 as the next digit in the result. 
Result so far: 72585.7301587
Deduct 5292 from 5520 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 16:
2280 divided by 756 is 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 72585.73015873
If we take 2268 away from 2280, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 72585.73015873, and the remainder is 1.2e-08.
