54690607 divided by 756 
The aim is to understand the frequency of 756 in 54690607.

On to step 1:
If we divide 5 by 756, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 756

Step 2:
If we divide 54 by 756, we get 0 and 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 (6) from the dividend, attach it to 54 and continue: 546 / 756

On to step 3:
If we divide 546 by 756, we get 0 and a remainder of 546.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 546 after subtracting 0 from 546.
Grab the next digit (9) from the dividend, add it to 546, then carry on: 5469 / 756

Advancing to step 4:
756 can be fit into 5469 7 times, resulting in a remainder of 177.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 5292 from 5469, we get 177.
Grab the next digit (0) from the dividend, add it to 177, then carry on: 1770 / 756

Moving on to step 5:
When dividing 1770 by 756, we get 2 with a remainder of 258.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Deduct 1512 from 1770 and we're left with 258.
Fetch the next digit (6) from the dividend, attach it to 258 and continue: 2586 / 756

On to step 6:
756 can be fit into 2586 3 times, resulting in a remainder of 318.
The next digit of our result is 3. 
Result so far: 723.0
The remainder is 318 after subtracting 2268 from 2586.
Take the next digit (0) from the dividend and append it to 318, then repeat: 3180 / 756

Moving on to step 7:
3180 divided by 756 is 4 with a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 7234.0
Deduct 3024 from 3180 and we're left with 156.
Fetch the next digit (7) from the dividend, attach it to 156 and continue: 1567 / 756

On to step 8:
756 goes into 1567 2 times with a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 72342.0
Subtract 1512 from 1567 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
756 goes into 550 0 times with a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 72342.0
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 10:
5500 divided by 756 is 7 with a remainder of 208.
Record the quotient 7 as the next digit in the result. 
Result so far: 72342.07
Deduct 5292 from 5500 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 11:
2080 divided by 756 is 2 with a remainder of 568.
Record the quotient 2 as the next digit in the result. 
Result so far: 72342.072
Deduct 1512 from 2080 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 12:
The number 756 fits into 5680 7 times, leaving a remainder of 388.
Use 7 as the next digit of our solution. 
Result so far: 72342.0727
Subtract 5292 from 5680 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 13:
756 can be fit into 3880 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 72342.07275
If we subtract 3780 from 3880, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 14:
The number 756 fits into 1000 1 times, leaving a remainder of 244.
Put 1 as the next digit of the answer. 
Result so far: 72342.072751
If we take 756 away from 1000, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 15:
The number 756 fits into 2440 3 times, leaving a remainder of 172.
Write down 3 as next digit of the result. 
Result so far: 72342.0727513
The remainder is 172 after subtracting 2268 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 16:
The number 756 fits into 1720 2 times, leaving a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 72342.07275132
If we subtract 1512 from 1720, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final outcome is 72342.07275132, with a leftover of 2.08e-07.
