We look at the division of 53231763 by 751 
The aim is to understand the frequency of 751 in 53231763.

Going ahead to step 1:
When dividing 5 by 751, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 751

Step 2:
When dividing 53 by 751, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 751

Let's proceed to step 3:
751 goes into 532 0 times with a remainder of 532.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 532 and we're left with 532.
Take the next digit (3) from the dividend and append it to 532, then repeat: 5323 / 751

Moving on to step 4:
5323 divided by 751 is 7 with a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 66 after subtracting 5257 from 5323.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 751

Step 5:
661 divided by 751 is 0 with a remainder of 661.
The next digit of our result is 0. 
Result so far: 70.0
Deduct 0 from 661 and we're left with 661.
Bring next digit (7) of the dividend behind the 661 and repeat the process: 6617 / 751

Advancing to step 6:
6617 divided by 751 is 8 with a remainder of 609.
Put 8 as the next digit of the answer. 
Result so far: 708.0
If we take 6008 away from 6617, we end up with 609.
Include the next digit (6) from the dividend after 609, then repeat: 6096 / 751

Advancing to step 7:
751 can be fit into 6096 8 times, resulting in a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 7088.0
Deduct 6008 from 6096 and we're left with 88.
Grab the next digit (3) from the dividend, add it to 88, then carry on: 883 / 751

Advancing to step 8:
When dividing 883 by 751, we get 1 with a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 70881.0
Subtracting 751 from 883 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 9:
If we divide 1320 by 751, we get 1 and a remainder of 569.
Put 1 as the next digit of the answer. 
Result so far: 70881.1
Deduct 751 from 1320 and we're left with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

On to step 10:
The number 751 fits into 5690 7 times, leaving a remainder of 433.
The next digit of our result is 7. 
Result so far: 70881.17
Subtracting 5257 from 5690 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 11:
751 can be fit into 4330 5 times, resulting in a remainder of 575.
Record the quotient 5 as the next digit in the result. 
Result so far: 70881.175
The remainder is 575 after subtracting 3755 from 4330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 12:
The number 751 fits into 5750 7 times, leaving a remainder of 493.
Write down 7 as next digit of the result. 
Result so far: 70881.1757
If we subtract 5257 from 5750, we get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Moving on to step 13:
The number 751 fits into 4930 6 times, leaving a remainder of 424.
Write down 6 as next digit of the result. 
Result so far: 70881.17576
If we take 4506 away from 4930, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 14:
751 goes into 4240 5 times with a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 70881.175765
Subtract 3755 from 4240 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Advancing to step 15:
751 goes into 4850 6 times with a remainder of 344.
Record the quotient 6 as the next digit in the result. 
Result so far: 70881.1757656
If we take 4506 away from 4850, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 16:
751 can be fit into 3440 4 times, resulting in a remainder of 436.
Put 4 as the next digit of the answer. 
Result so far: 70881.17576564
The remainder is 436 after subtracting 3004 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The final outcome is 70881.17576564, with a leftover of 4.36e-07.
