We look at the division of 53872945 by 759 
The aim is to understand the frequency of 759 in 53872945.

Advancing to step 1:
The number 759 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 759

Let's proceed to step 2:
759 goes into 53 0 times with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 759

Advancing to step 3:
538 divided by 759 is 0 with a remainder of 538.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 538 and we're left with 538.
Take the next digit (7) from the dividend and append it to 538, then repeat: 5387 / 759

Advancing to step 4:
5387 divided by 759 is 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 5313 from 5387, we get 74.
Take the next digit (2) from the dividend and append it to 74, then repeat: 742 / 759

Moving on to step 5:
When dividing 742 by 759, we get 0 with a remainder of 742.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Deduct 0 from 742 and we're left with 742.
Append the next digit (9) from the dividend to 742 and continue with: 7429 / 759

Going ahead to step 6:
759 goes into 7429 9 times with a remainder of 598.
Write down 9 as next digit of the result. 
Result so far: 709.0
The remainder is 598 after subtracting 6831 from 7429.
Append the next digit (4) from the dividend to 598 and continue with: 5984 / 759

Let's proceed to step 7:
If we divide 5984 by 759, we get 7 and a remainder of 671.
The number 7 becomes the next digit in our result. 
Result so far: 7097.0
If we take 5313 away from 5984, we end up with 671.
Grab the next digit (5) from the dividend, add it to 671, then carry on: 6715 / 759

On to step 8:
759 can be fit into 6715 8 times, resulting in a remainder of 643.
Use 8 as the next digit of our solution. 
Result so far: 70978.0
If we subtract 6072 from 6715, we get 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

On to step 9:
6430 divided by 759 is 8 with a remainder of 358.
Put 8 as the next digit of the answer. 
Result so far: 70978.8
Deduct 6072 from 6430 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 10:
759 can be fit into 3580 4 times, resulting in a remainder of 544.
The number 4 becomes the next digit in our result. 
Result so far: 70978.84
The remainder is 544 after subtracting 3036 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 11:
The number 759 fits into 5440 7 times, leaving a remainder of 127.
The number 7 becomes the next digit in our result. 
Result so far: 70978.847
If we subtract 5313 from 5440, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 12:
759 can be fit into 1270 1 times, resulting in a remainder of 511.
Put 1 as the next digit of the answer. 
Result so far: 70978.8471
If we subtract 759 from 1270, we get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Going ahead to step 13:
The number 759 fits into 5110 6 times, leaving a remainder of 556.
The number 6 becomes the next digit in our result. 
Result so far: 70978.84716
Subtracting 4554 from 5110 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 14:
759 can be fit into 5560 7 times, resulting in a remainder of 247.
Write down 7 as next digit of the result. 
Result so far: 70978.847167
Deduct 5313 from 5560 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 15:
2470 divided by 759 is 3 with a remainder of 193.
Write down 3 as next digit of the result. 
Result so far: 70978.8471673
Subtracting 2277 from 2470 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 16:
1930 divided by 759 is 2 with a remainder of 412.
Record the quotient 2 as the next digit in the result. 
Result so far: 70978.84716732
The remainder is 412 after subtracting 1518 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

After the division, we end up with 70978.84716732 and a remainder of 4.12e-07.
