We look at the division of 53914039 by 758 
The aim is to understand the frequency of 758 in 53914039.

Step 1:
758 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 758

On to step 2:
758 can be fit into 53 0 times, resulting in a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 758

On to step 3:
When dividing 539 by 758, we get 0 with a remainder of 539.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 539 to get 539.
Grab the next digit (1) from the dividend, add it to 539, then carry on: 5391 / 758

Advancing to step 4:
758 can be fit into 5391 7 times, resulting in a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 5306 away from 5391, we end up with 85.
Bring next digit (4) of the dividend behind the 85 and repeat the process: 854 / 758

On to step 5:
The number 758 fits into 854 1 times, leaving a remainder of 96.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Deduct 758 from 854 and we're left with 96.
Include the next digit (0) from the dividend after 96, then repeat: 960 / 758

On to step 6:
When dividing 960 by 758, we get 1 with a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 711.0
Subtracting 758 from 960 leaves us with 202.
Append the next digit (3) from the dividend to 202 and continue with: 2023 / 758

Going ahead to step 7:
2023 divided by 758 is 2 with a remainder of 507.
Write down 2 as next digit of the result. 
Result so far: 7112.0
Subtract 1516 from 2023 to get 507.
Include the next digit (9) from the dividend after 507, then repeat: 5079 / 758

Going ahead to step 8:
The number 758 fits into 5079 6 times, leaving a remainder of 531.
Record the quotient 6 as the next digit in the result. 
Result so far: 71126.0
The remainder is 531 after subtracting 4548 from 5079.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 9:
If we divide 5310 by 758, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 71126.7
Deduct 5306 from 5310 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
When dividing 40 by 758, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 71126.7
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
758 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 71126.7
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 71126.7 with a remainder of 0.04.
