We're dividing 7521902 by 959 
The aim is to understand the frequency of 959 in 7521902.

On to step 1:
7 divided by 959 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 959

Moving on to step 2:
The number 959 fits into 75 0 times, leaving a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 959

Step 3:
959 goes into 752 0 times with a remainder of 752.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 752 leaves us with 752.
Grab the next digit (1) from the dividend, add it to 752, then carry on: 7521 / 959

Moving on to step 4:
959 goes into 7521 7 times with a remainder of 808.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 6713 away from 7521, we end up with 808.
Append the next digit (9) from the dividend to 808 and continue with: 8089 / 959

Let's proceed to step 5:
8089 divided by 959 is 8 with a remainder of 417.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Deduct 7672 from 8089 and we're left with 417.
Append the next digit (0) from the dividend to 417 and continue with: 4170 / 959

Moving on to step 6:
If we divide 4170 by 959, we get 4 and a remainder of 334.
The next digit of our result is 4. 
Result so far: 784.0
If we take 3836 away from 4170, we end up with 334.
Include the next digit (2) from the dividend after 334, then repeat: 3342 / 959

Moving on to step 7:
3342 divided by 959 is 3 with a remainder of 465.
Use 3 as the next digit of our solution. 
Result so far: 7843.0
Subtract 2877 from 3342 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

On to step 8:
The number 959 fits into 4650 4 times, leaving a remainder of 814.
Write down 4 as next digit of the result. 
Result so far: 7843.4
The remainder is 814 after subtracting 3836 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Advancing to step 9:
959 goes into 8140 8 times with a remainder of 468.
Write down 8 as next digit of the result. 
Result so far: 7843.48
The remainder is 468 after subtracting 7672 from 8140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 10:
The number 959 fits into 4680 4 times, leaving a remainder of 844.
Put 4 as the next digit of the answer. 
Result so far: 7843.484
The remainder is 844 after subtracting 3836 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Advancing to step 11:
8440 divided by 959 is 8 with a remainder of 768.
Record the quotient 8 as the next digit in the result. 
Result so far: 7843.4848
Subtract 7672 from 8440 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Let's proceed to step 12:
If we divide 7680 by 959, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 7843.48488
The remainder is 8 after subtracting 7672 from 7680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 7843.48488 with a remainder of 8e-06.
