Let's divide 87592643 by 753
The aim is to understand the frequency of 753 in 87592643.

On to step 1:
When dividing 8 by 753, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 753

Going ahead to step 2:
When dividing 87 by 753, we get 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (5) from the dividend and append it to 87, then repeat: 875 / 753

On to step 3:
If we divide 875 by 753, we get 1 and a remainder of 122.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 753 from 875, we get 122.
Append the next digit (9) from the dividend to 122 and continue with: 1229 / 753

On to step 4:
The number 753 fits into 1229 1 times, leaving a remainder of 476.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 753 from 1229 to get 476.
Include the next digit (2) from the dividend after 476, then repeat: 4762 / 753

Step 5:
753 can be fit into 4762 6 times, resulting in a remainder of 244.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtracting 4518 from 4762 leaves us with 244.
Fetch the next digit (6) from the dividend, attach it to 244 and continue: 2446 / 753

Moving on to step 6:
When dividing 2446 by 753, we get 3 with a remainder of 187.
Write down 3 as next digit of the result. 
Result so far: 1163.0
If we take 2259 away from 2446, we end up with 187.
Grab the next digit (4) from the dividend, add it to 187, then carry on: 1874 / 753

On to step 7:
The number 753 fits into 1874 2 times, leaving a remainder of 368.
Write down 2 as next digit of the result. 
Result so far: 11632.0
The remainder is 368 after subtracting 1506 from 1874.
Bring next digit (3) of the dividend behind the 368 and repeat the process: 3683 / 753

On to step 8:
If we divide 3683 by 753, we get 4 and a remainder of 671.
The number 4 becomes the next digit in our result. 
Result so far: 116324.0
If we take 3012 away from 3683, we end up with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Step 9:
When dividing 6710 by 753, we get 8 with a remainder of 686.
Use 8 as the next digit of our solution. 
Result so far: 116324.8
If we subtract 6024 from 6710, we get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Let's proceed to step 10:
753 goes into 6860 9 times with a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 116324.89
If we subtract 6777 from 6860, we 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.

Advancing to step 11:
830 divided by 753 is 1 with a remainder of 77.
The next digit of our result is 1. 
Result so far: 116324.891
Subtracting 753 from 830 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 12:
770 divided by 753 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 116324.8911
The remainder is 17 after subtracting 753 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 116324.8911, with a leftover of 0.00017.
